Complex motor tasks often consist of multiple simple actions performed in a specific sequence.

New step in DNA damage response in neurons discovered

Researchers have identified a biochemical switch required for nerve cells to respond to DNA damage.

Neurons show sex-dependent changes during starvation

When it comes to keeping brains alive, it seems nature has deemed that females are more valuable then males. As reported in this weeks' JBC, researchers found that nutrient deprivation of neurons produced sex-dependent effects.

Channel Subunits Are Heterogeneously Expressed in AIS

An action potential's threshold and shape are governed by the distribution and subunit composition of voltage-gated sodium and potassium channels in the axon.

Patient-derived induced stem cells retain disease traits

When neurons started dying in Clive Svendsen's lab dishes, he couldn't have been more pleased.

Mediator in communication between neurons and muscle cells found

harminka — Thu, 23 Oct 2008 10:04:03 -0500

A missing piece of the puzzle of how neurons and muscle cells establish lifelong communication has been found by researchers who suspect this piece may be mutated and/or attacked in muscular dystrophy.

Modeling Electrophysiological Diversity

Variations in morphology and ion-channel expression largely determine the electrophysiological properties of neurons.

Caltech scientists decipher neurological basis of timely movement

Contrary to what one might imagine, the way in which each of us interacts with the world is not a simple matter of seeing (or touching, or smelling) and then reacting. Even the best baseball hitter eyeing a fastball does not swing at what he sees. The neurons and neural connections that make up our sensory systems are far too slow for this to work.

Molecular scaffold that guides connections between brain cells

harminka — Wed, 21 May 2008 08:06:10 -0500

Brain cells known as neurons process information by joining into complex networks, transmitting signals to each other across junctions called synapses. But “neurons don’t just connect to other neurons,” emphasizes Z. Josh Huang, Ph.D., “in a lot of cases, they connect to very specific partners, at particular spots.”

Neurons duke it out for survival

The developing nervous system makes far more nerve cells than are needed to ensure target organs and tissues are properly connected to the nervous system. As nerves connect to target organs, they somehow compete with each other resulting in some living and some dying.

Looking at neurons from all sides

A new technique that marries a fast-moving laser beam with a special microscope that look at tissues in different optical planes will enable scientists to get a three-dimensional view of neurons or nerve cells as they interact, said Baylor College of Medicine scientists in a report that appears today in the journal Nature Neuroscience.

Neurons hard wired to tell left from right

harminka — Mon, 31 Mar 2008 03:18:31 -0500

It's well known that the left and right sides of the brain differ in many animal species and this is thought to influence cognitive performance and social behaviour. For instance, in humans, the left half of the brain is concerned with language processing whereas the right side is better at comprehending musical melody.
