Neurobiology: Efficiency measures
Michael R. DeWeese1 & Anthony Zador1
Abstract
The nervous system translates sensory information into electrical impulses. The neural 'code' involved seems to represent natural sounds and images efficiently, using the smallest number of impulses.
Our perception of the outside world relies on the transformation of physical signals (such as light and sound) into a pattern of neural impulses, or spikes. These spikes are then transmitted to higher brain regions, where they are further transformed into other patterns of sensory spikes, and ultimately into the motor spikes that mediate behaviour.
- Michael R. DeWeese and Anthony Zador are in the Cold Spring Harbor Laboratory, 1 Bungtown Road, Cold Spring Harbor, New York 11724, USA.
