In a breakthrough for understanding brain evolution, neuroscientists have shown that differences between primate brains - from the tiny marmoset to human – can be largely explained as consequences of the same genetic program. In research published in the Journal of Neuroscience, Professor Marcello Rosa and his team at Monash University's School of Biomedical Sciences and colleagues at Universidade Federal do Rio de Janeiro, in Brazil, used computer modelling to demonstrate that the...

Brain Handles Stress Better When Bodies Are Exercised

April Flowers for redOrbit.com - Your Universe Online A new study led by Princeton University reveals physical activity reorganizes the brain so that its response to stress is decreased. This makes anxiety less likely to interfere with normal brain function. The findings, published in The Journal of Neuroscience, show when regularly exercised mice experienced a stressor -- for example, exposure to cold water -- their brains exhibited a spike in the activity of neurons that shut off...

The hippocampus is a brain structure that plays a major role in the process of memory formation. It is not entirely clear how the hippocampus manages to string together events that are part of the same experience but are separated by "empty" periods of time. Now, new research published by Cell Press in the August 25 issue of the journal Neuron finds that there are neurons in the hippocampus that encode every sequential moment in a series of events that compose a discrete experience. "The...

Researchers at UT Southwestern Medical Center hope they have begun paving a new pathway in the fight against drug dependence. Their hypothesis "“ that increasing the normally occurring process of making nerve cells might prevent addiction "“ is based on a rodent study demonstrating that blocking new growth of specific brain nerve cells increases vulnerability for cocaine addiction and relapse. The study's findings, available in the Journal of Neuroscience, are the first to...

U.S. scientists say they have discovered rats engage in a mental re-enactment of their recent experiences when choosing what actions to take. Massachusetts Institute of Technology researchers said they recorded the activity of single neurons called place cells in a brain structure -- the hippocampus -- that has been shown to be crucial for learning and memory. They found place cells are activated in a unique pattern and sequence for each specific location in a maze. When examining the brain...
