Discovery of post-stimulus activated release implies new mechanisms for dopamine release
The neurotransmitter dopamine continues to be released for nearly an hour after neurons are stimulated, suggesting the existence of secondary mechanisms that allow for sustained availability of dopamine in different regions of the brain including areas critical for memory consolidation, drug... view more (2006-10-16)

MIT IDs mechanism behind fear
Researchers from MIT's Picower Institute for Learning and Memory have uncovered a molecular mechanism that governs the formation of fears stemming from traumatic events.   view more (2007-07-16)

Neural stem cell gene plays crucial role in eye development
Scientists at the University of North Carolina at Chapel Hill have demonstrated that normal development of the eye requires the right amount of a neural stem cell gene be expressed at the right time and place.   view more (2006-05-16)

Weill Cornell Team Discovers How Brain's Own tPA Helps Regulate Blood Flow to Neurons
The human brain contains its own store of a powerful enzyme (and stroke drug) called tissue plasminogen activator (tPA), which appears to be a key regulator of blood flow to brain cells, a team at the Weill Cornell Medical College in New York City reports.   view more (2008-01-18)

Women on hormone therapy regain emotion response
Older women on hormone therapy are more sensitive to negative events, confirming speculation that age-related estrogen loss affects the brain's ability to process emotion, an Oregon Health & Science University study shows.   view more (2006-10-17)

Chromium picolinate linked with reduced carbohydrate cravings in people with atypical depression
Carbohydrate cravings, weight gain and unexplained fatigue are characteristic symptoms of atypical depression, a common but frequently undiagnosed depressive disorder affecting up to 42 percent of the 19 million Americans diagnosed with depression.   view more (2005-09-29)

UCLA Researchers Discover Link Between Parkinson's and Narcolepsy
Parkinson's disease is well-known for its progression of motor disorders: stiffness, slowness, tremors, difficulties walking and talking. Less well known is that Parkinson's shares other symptoms with narcolepsy, a sleep disorder characterized by sudden and uncontrollable episodes of deep sleep,... view more (2007-05-14)

Brain-computer link allows paralyzed patient to manipulate devices by thought
A patient with a spinal cord injury was able to produce brain signals associated with intending to move his paralyzed limbs, signals picked up by an implanted sensor and translated into electronic impulses that allowed him to control a computer cursor and manipulate mechanical devices.   view more (2006-07-13)

Adult brain can change, study confirms
It is well established that a child's brain has a remarkable capacity for change, but controversy continues about the extent to which such plasticity exists in the adult human primary sensory cortex.   view more (2007-09-06)

Brain needs perfection in synapse number
The proper number of synapses or communication between nerve cells, determined early in life, is crucial to having a healthy brain that can learn and retain information.   view more (2007-10-04)

Tunes and Talk: Researchers Find Music and Language are Processed by the Same Brain Systems
Researchers have long debated whether or not language and music depend on common processes in the mind. Now, researchers at Georgetown University Medical Center have found evidence that the processing of music and language do indeed depend on some of the same brain systems.    view more (2007-09-28)

Role of noise in neurons
Addressing a current issue in neuroscience, Aldo Faisal and Simon Laughlin from Cambridge University investigate the reliability of thin axons for transmitting information. They show that noise effects in ion channels in the brain are much larger than previously assumed - meaning the fidelity of... view more (2007-05-04)

Finding out which parts of the brain do what
Ever since the Greeks proposed that different parts of the brain housed different parts of the ‘soul’, mankind has tried to discover where our mental functions are located. This evening, Thursday 22 February, in a public lecture at the Royal Society, 6 Carlton House Terrace, London SW1Y... view more (2001-02-15)

Multiple genetic 'flavors' may explain autism
While debate still rages over the 'cause' of autism, mounting evidence suggests that genetic factors play a major role in the disease. Two recent studies led by James Sutcliffe, Ph.D., and Randy Blakely, Ph.D., investigators with the Vanderbilt Center for Molecular Neuroscience and the Vanderbilt... view more (2005-07-26)

Barrow scientists make headlines for their research on fixational eye movements
Susana Martinez-Conde, Ph.D., director of the Laboratory of Visual Neuroscience, and Stephen Macknik, Ph.D., director of the Laboratory of Behavioral Neurophysiology at Barrow Neurological Institute at St. Joseph's Hospital and Medical Center, are featured on the cover of the August issue of... view more (2007-07-25)

Are Anxiety Disorders All in the Mind?
Using single-photon emission computed tomography (SPECT), researchers in The Netherlands were able to detect biochemical differences in the brains of individuals with generalized social anxiety disorder (also known as social phobia), providing evidence of a long-suspected biological cause for the... view more (2008-05-13)

If you want more babies, find a man with a deep voice
Men who have lower-pitched voices have more children than do men with high-pitched voices, researchers have found. And their study suggests that for reproductive-minded women, mate selection favours men with low-pitched voices.   view more (2007-09-25)

Interactive 3-D atlas of mouse brain now available on web
Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have just launched a web-based 3-D digital atlas browser and database of the brain of a popular laboratory mouse.   view more (2005-12-01)

UCLA/VA research analysis in journal Nature explains wide variations in animal sleep habits
An extensive research analysis by a neuroscientist at UCLA's Semel Institute and the Veterans Affairs' Neurobiology Research Laboratory concludes that environment and diet largely determine sleep needs.   view more (2005-10-27)

UWE Scientists Help Bring Computers And Robots To Life
New sources of computing power - derived from such novel areas as neuron-like cells and powerful chemical reactions - could form the heart of the next generation of computers. The University of the West of England and four research partners have just won £1.8 million in government funding to... view more (2004-07-22)

Research Councils unveil a vision for research
The grand challenges for the future in UK research and the benefits that will come from them is the focus of the Research Councils UK report 'A Vision for Research', published this week. From discovering what the universe is made of to advances in the philosophy of language, the report sets out key... view more (2003-12-12)

New brain cells listen before they talk
Newly created neurons in adults rely on signals from distant brain regions to regulate their maturation and survival before they can communicate with existing neighboring cells-a finding that has important implications for the use of adult neural stem cells to replace brain cells lost by trauma or... view more (2007-10-31)

Heavy marijuana use linked to gum disease
Heavy marijuana use has been found to contribute to gum disease, apart from the known effects that tobacco smoke was already known to have.   view more (2008-02-06)

A molecular basis for selective therapeutic intervention in Alzheimer's disease

Distinguishing between 2 birds of a feather
The bird enthusiast who chronicled the adventures of a flock of red-headed conures in his book "The Wild Parrots of Telegraph Hill" knows most of the parrots by name, yet most of us would be hard pressed to tell one bird from another.   view more (2008-08-11)
