Brain

DURHAM, N.C. -- Engineers and neuroscientists at Duke University have developed a method to measure the response of an individual neuron to transcranial magnetic stimulation (TMS) of the brain. The advance will help researchers understand the underlying physiological effects of TMS -- a procedure used to treat psychiatric disorders -- and optimize its use as a therapeutic treatment.

CAMBRIDGE, MA -- Optogenetics, a technology that allows scientists to control brain activity by shining light on neurons, relies on light-sensitive proteins that can suppress or stimulate electrical signals within cells. This technique requires a light source to be implanted in the brain, where it can reach the cells to be controlled.

Without a steady supply of blood, neurons can't work. That's why one of the culprits behind Alzheimer's disease is believed to be the persistent blood clots that often form in the brains of Alzheimer's patients, contributing to the condition's hallmark memory loss, confusion and cognitive decline.

BUFFALO, N.Y. — New evidence suggests heinous behavior played out in a virtual environment can lead to players' increased sensitivity toward the moral codes they violated.

That is the surprising finding of a study led by Matthew Grizzard, PhD, assistant professor in the University at Buffalo Department of Communication, and co-authored by researchers at Michigan State University and the University of Texas, Austin.

PORTLAND, Ore. — Researchers with Oregon Health & Science University's Vollum Institute have given science a new and unprecedented 3-D view of one of the most important receptors in the brain — a receptor that allows us to learn and remember, and whose dysfunction is involved in a wide range of neurological diseases and conditions, including Alzheimer's, Parkinson's, schizophrenia and depression.

HAMILTON, ON, June 27, 2014—Developmental psychologist Daphne Maurer has spent more than four decades studying the complexities of the human mind.

As the director of the Visual Development Lab at McMaster University and president of the International Society on Infant Studies, Maurer will present her life's work at the Biennial International Conference on Infant Studies in Berlin July 4th.

Humans have a well-documented tendency to see winning and losing streaks in situations that, in fact, are random. But scientists disagree about whether the "hot-hand bias" is a cultural artifact picked up in childhood or a predisposition deeply ingrained in the structure of our cognitive architecture.

Alexandria, Va. — "Hello World." Upon hearing that brief message, scientists at the European Space Agency (ESA) and followers around the world sent up a collective cheer. Rosetta — the ESA spacecraft currently on a 10-year mission to orbit and land on a comet — awoke in January after a three-year hibernation, and was ready to get to work.

MADISON, Wis. — For children, stress can go a long way. A little bit provides a platform for learning, adapting and coping. But a lot of it — chronic, toxic stress like poverty, neglect and physical abuse — can have lasting negative impacts.

Over the last few years, we've seen increasing dissent among liberals and conservatives on important issues such as gun control, health care and same-sex marriage. Both sides often have a difficult time reconciling their own views with their opposition, and many times it appears that liberals are unable to band together under a unifying platform. Why do conservatives appear to have an affinity for obeying leadership? And why do conservatives perceive greater consensus among politically like-minded others?

University of Iowa researchers have discovered a new form of neurotransmission that influences the long-lasting memory created by addictive drugs, like cocaine and opioids, and the subsequent craving for these drugs of abuse. Loss of this type of neurotransmission creates changes in brains cells that resemble the changes caused by drug addiction.

The findings, published June 22 in the journal Nature Neuroscience, suggest that targeting this type of neurotransmission might lead to new therapies for treating drug addiction.

Researchers from the University of Granada have shown that individual chronotype—that is, whether you are a "morning-type" or an "evening-type", depending on the time of day when your physiological functions are more active—markedly influences driving performance.

Boulder, Colorado, USA – In the July 2014 issue of GSA Today, Heather Petcovic of Western Michigan University and colleagues Alison Stokes and Joshua Caulkins examine the question of geoscientists' perceptions of the value of undergraduate field education. Despite being perceived as integral to both geoscience learning and professional preparation, little research exists on the types of field experiences that carry the most value.

Research published today in PLOS ONE by researchers at the University of Warwick indicates that sleep problems are associated with worse memory and executive function in older people.

Analysis of sleep and cognitive (brain function) data from 3,968 men and 4,821 women who took part in the English Longitudinal Study of Ageing (ELSA), was conducted in a study funded by the Economic and Social Research Council (ESRC). Respondents reported on the quality and quantity of sleep over the period of a month.

PHILADELPHIA (June 26, 2014)— In the first pilot study asking adults on the autism spectrum about their experiences with driving, researchers at Drexel University found significant differences in self-reported driving behaviors and perceptions of driving ability in comparison to non-autistic adults. As the population of adults with autism continues growing rapidly, the survey provides a first step toward identifying whether this population has unmet needs for educational supports to empower safe driving – a key element of independent functioning in many people's lives.
