- Experience affects new neuron survival in adult brain; study sheds light on learning, memory
03-22-2007 · EurekAlert!
Experience in the early development of new neurons in specific brain regions affects their survival and activity in the adult brain, new research shows. How these new neurons store information about these experiences may explain how they can affect learning and memory in adults.

- Neuron cell stickiness may hold key to evolution of the human brain
11-02-2006 · EurekAlert!
The stickiness of human neurons may have been a key factor in why the human brain evolved beyond the brains of our primate relatives. In a study comparing the genomes of humans, chimpanzees and other vertebrates, researchers at the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and Joint Genome Institute (JGI) found a strikingly high degree of genetic differences in DNA sequences that appear to regulate genes involved in nerve cell adhesion molecules.

- New method for reading DNA sheds light on basis of cell identity
07-01-2007 · EurekAlert!
By using a new kind of genomic technology, a new study unveils a special code -- not within DNA, but within the so-called "chromatin" proteins surrounding it -- that could unlock the mysterious developmental choices made by mammalian cells, allowing them to assume roles as diverse as liver cells and neurons.

- Growth factor stimulates rapid extension of key motor neurons in brain
11-03-2006 · EurekAlert!
A growth factor known to be important for the survival of many types of cells stimulates rapid extension of corticospinal motor neurons -- critical brain cells that connect the cerebral cortex with the spinal cord and that die in motor neuron diseases like amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease).

- Carnegie Mellon study reveals that odor discrimination is linked to the timing at which neurons fire
11-07-2006 · EurekAlert!
Timing is everything. For a mouse trying to discriminate between the scent of a tasty treat and the scent of the neighborhood cat, timing could mean life or death. In a striking discovery, Carnegie Mellon University scientists have linked the timing of inhibitory neuron activity to the generation of odor-specific patterns in the brain's olfactory bulb, the area of the brain responsible for distinguishing odors.

- Racing neurons control whether we stop or go
04-18-2007 · EurekAlert!
In the children's game "red light green light," winners are able to stop, and take off running again, more quickly than their comrades. New research reveals that a similar race goes on in our brains, with impulse control being the big winner.
