Zebrafish may hold key to understanding human nerve cell development
...n't just "glue" holding nerve cells together. Glia communicate with each other and even influence synapse formation between neurons. Piotrowski's research in zebrafish focuses on the development of sensory neurons known as hair cells. Like humans, zebrafish use hair cells to detect sound and motion.

...l Health (NIMH) have found newly born neurons that communicate via the chemical messenger GABA (gamma-aminobutyric acid) in adult rat cortex, seat of higher order "executive" functions, and in the striatum, site of habits, reward and motor skill learning. In the cortex, the new neurons appear to arise from previ...Cell research signals cancer hope

The breakthrough should help in the fight against cancer as understanding how these signals work in healthy cells means scientists can better investigate what happens when the signal ...Sequencing of marine bacterium will help study of cell communication

...ge one of the established views of how nerve cells communicate with one another. Every time we move, feel emotions, think or remember, the nerve cells, or neurons, in our body transmit messages to one another via chemical signals called neurotransmitters.
