Spectrotemporal features of the auditory cortex: the activation in response to dynamic ripples

Dave R.M Langers, Walter H Backes, Pim van Dijk
2003 NeuroImage  
In contrast to animal studies, the activation of the human auditory cortex in response to dynamic ripples has not yet been studied systematically; in this paper we investigate the magnitude and spatial  ...  Activation pattern The large extent of activation shows that the processing of the spectrotemporal dynamics of sound is not confined to one specialized region in the auditory cortex.  ...

Dynamics of Precise Spike Timing in Primary Auditory Cortex

M. Elhilali
2004 Journal of Neuroscience  
Although single units in primary auditory cortex (A1) exhibit accurate timing in their phasic response to the onset of sound (precision of a few milliseconds), paradoxically, they are unable to sustain  ...  Such a dual response, however, is contingent on the cell being driven by both fast and slow modulations, in that the response to the slowly modulated envelope gates the expression of the fine structure  ...  of dynamics observed in the cortex.  ...

Emergent tuning for learned vocalizations in auditory cortex
