Disproportionate tonotopic representation for processing CF-FM sonar signals in the mustache bat auditory cortex
作者： N Suga , P. Jen

摘要: The extent of cortical representation the peripheral sensory field depends on its importance for species behavior. orientation sound mustache bat (Pteronotus parnellii rubiginosus) invariably consists long constant-frequency and short frequency-modulated components is indispensable survival. A disproportionately large part auditory cortex this occupied by neurons processing predominant in signal Doppler-shifted echoes. This disproportionate related to features biologically significant signals comparable that somatosensory visual systems many mammals, but it has not previously been observed system.
