Finding the key to open the blood brain barrier (The Dana Foundation Website - 5 December 2011)

Neuroscientists are finding novel ways to open the blood brain barrier--to potentially deliver much-needed drugs to individuals with Alzheimer's or other neurodegenerative disorders.

Excerpt:

Potential drugs for neurodegenerative disorders such as multiple sclerosis (MS) and Alzheimer’s disease have been stymied by their inability to cross the blood brain barrier (BBB), a system of unique blood vessels that acts as a natural barricade between the brain and the rest of the body. This barrier, designed to block potentially harmful substances from reaching neural tissue, also holds back the very agents designed to target disease. But two new techniques, one using endogenous adenosine receptors and another using ultrasound, may offer doctors the ability to not only open the BBB but also control the length of time it remains open...

What neuroscience can teach us about love (Happen - November 2011)

Theo Pauline Nestor interviewed me for this Q&A about love and the brain. 

Excerpt:

When writer Kayt Sukel was perched to reenter the dating world, she was suddenly confronted with the fact that she could not answer what she thought of as the "relatively easy question" — namely, "what is love?"

"It was probably naïve of me to think of it as something 'easy,'" Sukel says, "but I had gotten some notion — probably from novels and sappy movies — that I should have a better handle on that dratted L-word by the time I got married and started a family. And then when my marriage fell apart, I felt like it was time to frame love-related questions in a different way — to see if maybe neuroscience might offer me some better insight than what I could find on the self-help shelves." With that in mind, Sukel set out on a quest to learn what answers neuroscientists could yield up in regards to the hard questions about love, lust, and monogamy. The results of her search can be found in her newly released book, Dirty Minds: How Our Brains Influence Love, Sex, and Relationships (Free Press, 2012), a thorough and lively investigation into the latest research on love and the brain...

For first time, researchers describe molecular mechanism for a 'gateway drug'—nicotine (The Dana Foundation Website - 22 November 2011)

Nicotine has long been thought to be a "gateway drug."  For the first time, the biological underpinnings of that gateway mechanism have been explained.

Excerpt:

A few years ago, I attended an open Alcoholics Anonymous meeting to support a friend in recovery. During a brief break, it was impossible not to notice how many attendees rushed outside for a cigarette. Epidemiological studies have long linked smoking to other forms of addiction—but, to date, they have been unable to establish any direct biological connections. A study published in the Nov. 2 issue of Science Translational Medicine, however, has now demonstrated how nicotine may accelerate both the cellular and epigenetic processes underlying addiction, providing the first biological explanation of a “gateway” drug...

Reactive temperament in infancy linked to amygdala activity later in life (The Dana Foundation Website - 18 November 2011)

Jerome Kagan's lab at Harvard University is finding that early temperament is linked to later activation differences in the amygdala.

Excerpt:

My great-grandmother once told me that babies keep only one trait throughout the course of their lifetime—their temperament. It would seem her folk wisdom was not far off the mark. A study  published in the Sept. 6 issue of Molecular Psychiatry, demonstrates that a male infant’s reaction to unexpected stimuli, a biological measure of temperament, can predict amygdala activity later in adulthood...

Brain Receptors - A Primer (The Dana Foundation Website - 4 November 2011)

Neural receptors play an important role in several neuropsychiatric disorders.  Here is a basic primer on how they work.

Excerpt:

Synaptic transmission begins when one brain cell releases a neurochemical into the synapse. The transmission, however, is not complete until that neurochemical binds with a receptor on the postsynaptic, or receiving, neuron. Researchers have learned that receptors are equally as important as the neurochemicals they receive in maintaining healthy neurobiology. In fact, studies have demonstrated that receptors play a critical role in mood, learning, and the formation of social bonds. Many receptors are current targets for drug development for treatment of psychiatric disorders...

At-risk alcoholism phenotype shows measureable brain changes (The Dana Foundation Website - 28 October 2011)

A new study may offer help in identifying those who are most at-risk for alcoholism.

Excerpt:

The National Institutes of Health estimate that nearly 18 million adults in the United States have an alcohol abuse disorder. Alcoholism is a disease that has great costs—to individuals, their families, and the public at large. While doctors are not currently able to predict who will become addicted to alcohol, research suggests that one’s level of sensitivity to it plays an important role. And a new study by scientists at the University of California, San Diego shows that this sensitivity changes how the brain processes information during a cognitive task—and may provide new information for prevention and education efforts...

Childhood trauma leaves lasting marks on the brain (The Dana Foundation Website - 24 October 2011)

New evidence suggests that physical and emotional trauma can make lasting changes to the brain. 

Excerpt:

"Common wisdom" has long linked childhood traumas such as physical and sexual abuse to psychopathology later in life. Now, an ongoing longitudinal study called the Adverse Childhood Experiences (ACE) study is providing strong evidence to back up that notion. Based on its results, researchers have added childhood abuse as a factor of interest in other studies, such as the Army’s ambitious suicide research program, the Study To Assess Risk and Resilience in Servicemembers (STARRS) project. ACE research results have also provided a foundation for researchers to examine how childhood abuse can cause physical changes to the brain and its development, putting the abused at greater risk for depression, addiction, and suicide in adulthood...

Your brain and online dating (Happen Magazine - October 2011)

What did I learn as I researched DIRTY MINDS that may help in the dating world?  I spilled some of the details to Happen, Match.com's magazine.

Excerpt:

Kayt Sukel is the author of Dirty Minds: How Our Brains Influence Love, Sex, and Relationships (Free Press, 2012). Here are a few things she learned about the neurobiology of attraction as she researched and wrote her book — and how they might apply to your online dating life.

Read through a dozen online dating profiles and I guarantee that you'll come across words like "chemistry," "spark," and "connection." There's good reason for this: as I researched the neurobiology of attraction for Dirty Minds, I quickly learned that chemistry is far more than just a dating profile cliché. Chemistry is real — and it's important. It just may not be exactly what you think it is...

Viral treatment may offer hope to brain tumor treatments (The Dana Foundation Website - 18 October 2011)

Scientists and clinicians at the Methodist Neurological Institute in Houston, Texas are re-engineering the herpes virus in order to treat a deadly form of brain tumor.

Excerpt:

People diagnosed with a particularly insidious form of brain cancer, glioblastoma multiforme, typically undergo invasive surgery to remove the malignant tumor, followed by intense courses of radiation and chemotherapy. Some find the treatment regimen is as debilitating as the cancer itself. Today, however, researchers at the Methodist Neurological Institute in Houston, Texas, and Massachusetts General Hospital are testing alternative treatments involving the herpes virus, immunosuppression and nanotechnology in hopes of providing both better outcomes—and quality of life—for people with this deadly form of brain cancer...

New Army risk and resilience project searches for signs of potential suicide (The Dana Foundation Website - 8 September 2011)

An ambitious new research project led by the U.S. Army and the National Institute of Mental Health hopes to find predictors of suicide for members of the military--and beyond.

Excerpt:

In the late 1940s, the National Heart Institute (now called the National Heart, Lung, and Blood Institute) launched the Framingham Heart Study, a longitudinal research project to investigate the biological precursors of cardiovascular disease. This study, still going strong, has informed much of what we know about the underlying risks of heart disease and stroke, as well as what we can do to best prevent and treat it. Now the U.S. Army, partnered with the National Institute of Mental Health (NIMH), is embarking on the Army Study To Assess Risk and Resilience in Servicemembers (STARRS), an ambitious series of research studies they hope will one day be considered the Framingham Heart Study of suicide and mental health. Its goal: To find reliable biomarkers for compromised mental health...

Is the neuroscientific study of pain lagging? (The Dana Foundation Website - 30 August 2011)

A remark at the One Mind for Research summit inspires the question, "Is the neuroscientific study of pain lagging?"

Excerpt:

Earlier this year, scientists, politicians and other healthcare advocates came together to share their hopes for the next decade of neuroscience research at the One Mind for Research (OMR) Summit in Boston. At a session highlighting the neurobiological consequences of war, Clifford J. Woolf, a pain researcher at Harvard Medical School and Children’s Hospital Boston, stated, “We have made enormous progress in promoting survival…but, in fact, an area that has really lagged behind relates to the pain associated with combat injury.”

Neural network mimics schizophrenia-like dopamine release in the brain (The Dana Foundation Website - 3 August 2011)

A neural network suggests that "hyper-learning," or a heightened release of dopamine in the brain that muddles the way schizophrenics remember language and events, may give us a better understanding of the factors leading to psychosis.

Excerpt:

Schizophrenia is a psychiatric disorder best known by its intense behavioral symptoms. Novels and television shows have well characterized the more obvious issues like auditory hallucinations, paranoid delusions, and disjointed patterns of thinking. To date, however, neuroscientists have been unable to fit this diverse group of symptoms—as well as others like lack of affect, disorganized speech, and cognitive decline—into a single, cohesive theory that can explain both the cause and the development of the disorder. Researchers from the University of Texas at Austin and Yale University hope that the use of a neural network nicknamed DISCERN may offer better insight into how problems in learning and excess dopamine release can confuse the way schizophrenics remember language and events, eventually building up to psychosis...

Neuroanatomy--A primer (The Dana Foundation Website - 15 July 2011)

The brain boasts a complex architecture.  Here are the basics of its build and make-up.

Excerpt:

The human brain is a unique structure that boasts a complex three-dimensional architecture. Neuroscientists are only beginning to understand how the different parts of this intricate configuration work together to produce behavior. In the numerous neuroimaging studies that are published weekly, researchers use common neuroanatomical terms to denote location, organization, and, at times, implied function. Though a complete discussion of neuroanatomy is worthy of a thick textbook full of elaborate illustrations, common terminology used in neuroscientific research is highlighted below...

Depression: Not just for adults (The Dana Foundation Website - 2 June 2011)

New research suggests not only that depression may occur in children as young as 3 years of age but that it is predictive of later episodes.

Excerpt:

From a distance, Callie¹ appears to be a normal if quiet 5-year-old girl. But when faced with a toy that blows large soap bubbles—an activity that makes the vast majority of kindergarteners squeal and leap with delight—she is uninterested in popping the bubbles or taking a turn with the gun herself. When offered dolls or other toys, she is equally unmoved. When groups of children congregate to play, Callie does not join them. Even at home, she is quiet and withdrawn. While Callie’s mother explains this lack of interest in play as simple “shyness,” researchers are now discovering that children as young as 3 years of age can meet the clinical criteria for major depressive disorder (MDD). What’s more, they demonstrate patterns of brain activation very similar to those seen in adults diagnosed with the disorder...

Will neuroscience challenge the legal concept of criminal responsibility? (The Dana Foundation Website - 24 May 2011)

Advances in neuroscience may challenge many notions held dear in the American legal system.  Hear what the experts have to say about whether it will challenge the concept of criminal responsibility.

Excerpt:

Just before 10:00 a.m. on June 20, 2001, a uniformed police officer was dispatched to do what he thought was a routine welfare check at a home in Houston, Texas. When the officer met Andrea Yates at the door, she immediately told him, “I just killed my kids.” When Yates was later asked why she drowned her five children, she claimed she had to in order to save them from hell. The police would learn that Yates had been suffering from long-term post-partum depression and psychosis...

Spinal cord injury: Study offers new way to predict who will walk again (The Dana Foundation Website - 14 April 2011)

A new testing protocol may help neurologists predict which individuals with severe spinal injuries will walk again. 

Excerpt:

Each year, thousands of Americans come to trauma centers across the country with devastating spinal cord injuries, often as the result of an automobile accident. Many die before they reach the hospital; for the survivors, recovery can vary significantly. Once a patient is stabilized after injury, the next question is invariably whether he or she will walk again. A study published in the March 19 issue of The Lancet suggests four simple measures may help physicians predict ambulation outcomes in these individuals with greater than 95 percent accuracy...

Beyond cuddling: Oxytocin and the brain (The Dana Foundation Website - 14 February 2011)

Oxytocin is a neurochemical with significant reach.  So it's no surprise that it was well represented at the Society for Neuroscience's annual conference.

Excerpt:

Despite the variety of research topics one can find at the annual Society for Neuroscience meeting, one word, oxytocin, kept popping up at this year’s conference. This small neuropeptide, produced in two specialized areas of the hypothalamus, was mentioned in nearly 100 abstracts published in the meeting program. Though oxytocin has long been linked to maternal and romantic bonds, giving it the nickname of the “cuddle chemical,” new research presented at Neuroscience 2010 suggests its reach goes far beyond cuddling. Oxytocin may have something to say about a variety of conditions and emotional states including autism, anxiety, happiness, and susceptibility to advertising messages. This research is still preliminary—researchers caution that they don't know what potential side-effects or long-term effects of taking the hormone may be...

Model predicts neural inhibition's effects on anxiety (The Dana Foundation Website - 20 December 2010)

A better understanding of neural inhibition may provide new clues into the study of anxiety.

Excerpt:

Imagine the smallest decision –what part of the newspaper to read first, what time to leave work to avoid rush hour, what kind of cereal to buy at the market – had the power to stop you in your tracks. People with anxiety often have trouble with these types of seemingly inconsequential decisions. Research reported Sept. 21 in the Proceedings of the National Academy of Sciences suggests this difficulty is due to a glitch in a process called neural inhibition...

Vitamin D found to influence more than 200 genes (The Dana Foundation Website - 1 December 2010)

A new study inks Vitamin D directly acts on over 200 genes and suggests the mechanism in which a lack of this hormone is linked to so many disease states.

Excerpt:

In the past few years, a deficiency in Vitamin D levels has been linked to a host of diseases from cardiovascular disease to cancer, but some scientists wondered if these associations were simply epidemiological artifact—a result of the analysis, not the substance. But researchers at the University of Oxford and the Wellcome Trust Centre for Human Genetics have now demonstrated that Vitamin D has direct influence on over 200 genes, including many implicated in disease. They published their results in the Aug. 24 issue of Genome Research...

Doing away with malaria (The Dana Foundation Website - 24 November 2010)

Scientists are taking different approaches in the fight against cerebral malaria, a devastating disease that affects millions in Africa and Asia.

Excerpt:

In July, pop singer and “X-Factor” judge Cheryl Cole made headlines not for her new record or impending divorce but for hospitalization due to malarial infection. This infectious disease, caused by the release of the Plasmodium falciparum parasite into the bloodstream from a mosquito bite, is both preventable and treatable. Yet it remains devastating to millions, particularly young children in sub-Saharan Africa and parts of Asia, who develop a form of the disease called cerebral malaria. This type of infection is characterized by severe damage to the blood vessels around the brain. And this damage results in coma, neurological damage and, too often, death (See also the Cerebrum story, Cerebral Malaria, a Wily Foe).

Brain size linked to longevity (The Dana Foundation Website - 8 November 2010)

Does the size of your brain say something about how long you'll live?  New research suggests that's the case.

Excerpt:

Many mammals have proportionally large brains in comparison with their respective body sizes. Scientists have long hypothesized that those big brains, found in such animals as primates, cetaceans, and humans, must signify big intelligence. Now, researchers from the Centre for Ecological Research and Forestry Applications (CREAF), part of the Universitat Autònoma de Barcelona, have found a strong correlation between brain size and long life—and that longevity may be related to enhanced cognitive abilities...

Should genes be patented? (Proto Magazine - Fall 2010)

Hundreds of genes have already been patented by various healthcare companies--but the question remains, should they be?

Excerpt:

If women with a family history of breast or ovarian cancer want to check for mutations of their BRCA1 and BRCA2 genes, which can help predict the likelihood of the diseases, they have exactly one option: undergo a blood test created by Myriad Genetics. That’s because Myriad holds a series of patents relating to both genes, protecting its intellectual property and restricting other laboratories from performing the test. But in March, a federal judge ruled in favor of plaintiffs who argued that genes shouldn’t be patented—a decision that could affect the holders of thousands of gene patents issued since 1982...

Effects of genomic imprinting are dynamic throughout life (The Dana Foundation Website - 8 October 2010)

Scientists at Harvard University show that genomic imprinting is a dynamic process, with some genes being affected at different points in the lifespan.

Excerpt:

Every cell in the human body, be it liver cell or blood cell or neuron, develops and runs on the same DNA. Mammals, for the most part, have two copies of every gene, a copy inherited from both the mother and the father, providing a handy backup in case one of the two is damaged. But nearly two decades ago, scientists discovered that for a limited number of genes, only one copy is active—the second is turned off by a regulatory process known as genomic imprinting...

Should psychiatrists prescribe exercise for depression? (The Dana Foundation Website - 30 June 2010)

Study after study is showing that exercise can lift mood.  But is there enough evidence so psychiatrists will start writing "exercise" on their prescription pads?

Excerpt:

After Joshua Berman, 39, was diagnosed with depression, he tried several different antidepressant medications to alleviate his symptoms. He finally found some success with one medication—but that success came with a price.

“I didn’t have a lot of energy. It hindered me from getting up in the morning,” says Berman. “[The medication] stabilized my mood better than anything else had but I still had affect issues and trouble sleeping most nights.”
