Cracking the neuronal code

Article Abstract:

The prevailing theory of neuronal information exchange, in which the firing rate of a neuron determines the strength of a single stimulus, is being challenged by a temporal code model. Recent experiments and theory suggest that a single neuron can signal the existence of several different stimuli.

Ensemble activity and behavior: what's the code?

Article Abstract:

Sequential single-electrode recordings of neuron activity pieced together to reconstruct models of neural networks was cumbersome and inadequate. New technologies allow recording and data analysis of neural spike data in ensemble. Recent research is described.

Is neural noise just a nuisance?

Article Abstract:

Research indicates that the noise among neurons that have similar receptive field properties is highly correlated. This discovery invalidates the assumption that the brain can obtain low-noise signals by averaging the among populations of neurons.
