Researchers regenerate axons necessary for voluntary movement

For the first time, researchers have clearly shown regeneration of a critical type of nerve fiber that travels between the brain and the spinal cord and which is required for voluntary movement.

How the retina works: Like a multi-layered jigsaw puzzle of receptive fields

About 1.25 million neurons in the retina -- each of which views the world only through a small jagged window called a receptive field -- collectively form the seamless picture we rely on to navigate our environment.

Scientists show how a neuron gets its shape

Ask a simple question, get a simple answer: When Abraham Lincoln was asked how long a man's legs should be, he absurdly replied, "Long enough to reach the ground."

Researchers find direct link between bursting activity of midbrain dopamine neurons and behavior

Researchers are one step closer to understanding the neurobiology that allows people to successfully learn motivated behaviors by associating environmental cues with rewarding outcomes, according to a study published yesterday in the Proceedings of the National Academy of Sciences ' online Early Edition.

55 proteins found to interact with nicotine

Nicotine isn't just addictive. It may also interfere with dozens of cellular interactions in the body, new Brown University research suggests.

Alzheimer's disease linked to mitochondrial damage

Investigators at the Burnham Institute for Medical Research (Burnham) have demonstrated that attacks on the mitochondrial protein Drp1 by the free radical nitric oxide-which causes a chemical reaction called S-nitrosylation-mediates neurodegeneration associated with Alzheimer's disease.

What drives brain changes in macular degeneration?

In macular degeneration, the most common form of adult blindness, patients progressively lose vision in the center of their visual field, thereby depriving the corresponding part of the visual cortex of input.

A new theory on autism put forward

Scientists at Albert Einstein College of Medicine of Yeshiva University have proposed a sweeping new theory of autism that suggests that the brains of people with autism are structurally normal but dysregulated, meaning symptoms of the disorder might be reversible.

Model brain explains limitations of working memory

Researchers at the Swedish medical university Karolinska Institutet (KI) have constructed a mathematical activity model of the brain's anterior and superior parts, to increase the understanding of the capacity of the working memory and of how the billions of neurons in the brain interact.
