Anesthesia and brain sensory processing: impact on neuronal responses in a female songbird

Sci Rep. 2016 Dec 14:6:39143. doi: 10.1038/srep39143.

Abstract

Whether anesthesia impacts brain sensory processing is a highly debated and important issue. There is a general agreement that anesthesia tends to diminish neuronal activity, but its potential impact on neuronal "tuning" is still an open question. Here we show, based on electrophysiological recordings in the primary auditory area of a female songbird, that anesthesia induces neuronal responses towards biologically irrelevant sounds and prevents the seasonal neuronal tuning towards functionally relevant species-specific song elements.
