Review announcement

This review describes a constructive role for noise in synchronizing 
populations of neurons and should be of interest to computaional

    Reliability, synchrony and noise.

The brain is noisy. Neurons receive tens of thousands of highly 
fluctuating inputs and generate spike trains that appear highly 
irregular. Much of this activity is spontaneous - uncoupled to overt 
stimuli or motor outputs - leading to questions about the functional 
impact of this noise. Although noise is most often thought of as 
disrupting patterned activity and interfering with the encoding of 
stimuli, recent theoretical and experimental work has shown that noise 
can play a constructive role - leading to increased reliability or 
regularity of neuronal firing in single neurons and across populations. 
These results raise fundamental questions about how noise can influence 
neural function and computation.
