MIT– parts of brain can switch functions

Cambridge, MASS- When your brain encounters sensory stimuli, such as the scent of your morning coffee or the sound of a honking car, that input gets shuttled to the appropriate brain region for analysis. The coffee aroma goes to the olfactory cortex...

Researchers have found how brain cells control their movement to form...

A study led by Academy Research Fellow Eleanor Coffey identifies new players that put the brakes on. They show in mice that lack the star player "JNK1", that newborn neurons spend less time in the multipolar stage, which is when the cells prepare fo...

Chinks in the brain circuitry make some more vulnerable to anxiety

Why do some people fret over the most trivial matters while others remain calm in the face of calamity? Researchers at the University of California, Berkeley, have identified two different chinks in our brain circuitry that explain why some of us ar...

Revealing the wiring that allows us to adapt to the unexpected

Milan, Italy, 31 January 2010 -- Wouldn't life be easy if everything happened as we anticipated? In reality, our brains are able to adapt to the unexpected using an inbuilt network that makes predictions about the world and monitors how those predi...

The changing roles of 2 hemispheres in stroke recovery

Milan, Italy, 31 January 2010 -- Most people who survive a stroke recover some degree of their motor, sensory and cognitive functions over the following months and years. This recovery is commonly believed to reflect a reorganisation of the central...

Neuronal migration errors: Right cells, wrong place

Philadelphia, PA, 4 January 2011 - Normally, cortical nerve cells or neurons reside in the brain's gray matter with only a few scattered neurons in the white matter, but some people with schizophrenia have a higher number of neurons in the white mat...

York U study pinpoints part of brain that suppresses instinct

TORONTO, December 22, 2010 − Research from York University is revealing which regions in the brain "fire up" when we suppress an automatic behaviour such as the urge to look at other people as we enter an elevator. A York study, published ...

CSHL scientists show in unprecedented detail how cortical nerve cells form...

Cold Spring Harbor, NY-- Newly published research led by Professor Z. Josh Huang, Ph.D., of Cold Spring Harbor Laboratory (CSHL) sheds important new light on how neurons in the developing brain make connections with one another. This activity, calle...

When the zebra loses its stripes

Milan, Italy, 20 December 2010 -- The capacity to remember that a zebra has stripes, or that a giraffe is a four-legged mammal, is known as semantic memory. It allows us to assign meaning to words and to recall general knowledge and concepts that w...
