Spectral and spatial tuning of onset and offset response functions in auditory cortical fields A1 and CL of rhesus macaques

In the current study, we examine the relationship between the tuning of neural responses evoked by the onset and offset of acoustic stimuli in the primary auditory cortex, as well as a higher-order auditory area—the caudolateral belt field—in awake rhesus macaques. In these areas, the relationship between onset and offset response profiles in frequency and space domains formed a continuum, ranging from highly overlapping to highly nonoverlapping.
