Energy as a constraint on the coding and processing of sensory information

Curr Opin Neurobiol. 2001 Aug;11(4):475-80. doi: 10.1016/s0959-4388(00)00237-3.


Neurons use significant amounts of energy to generate signals. Recent studies of retina and brain connect this energy usage to the ability to transmit information. The identification of energy-efficient neural circuits and codes suggests new ways of understanding the function, design and evolution of nervous systems.
