Tuning to Natural Stimulus Dynamics in Primary Auditory Cortex
The amplitude and pitch fluctuations of natural soundscapes often exhibit "1/f spectra", which means that large, abrupt changes in pitch or loudness occur proportionally less frequently in nature than gentle, gradual fluctuations. Furthermore, human listeners reportedly prefer 1/f distributed random melodies to melodies with faster (1/f0) or slower (1/f2) dynamics. One might therefore suspect t...
متن کاملInteractions across Multiple Stimulus Dimensions in Primary Auditory Cortex
Although sensory cortex is thought to be important for the perception of complex objects, its specific role in representing complex stimuli remains unknown. Complex objects are rich in information along multiple stimulus dimensions. The position of cortex in the sensory hierarchy suggests that cortical neurons may integrate across these dimensions to form a more gestalt representation of audito...
متن کاملDynamics of Spectro - Temporal Tuning in Primary Auditory Cortex of the Ferret
In this paper, we explore spectro-temporal tuning in primary auditory cortex following a sudden change in spectro-temporal content. We previously characterized the steady-state spectrotemporal tuning properties of cortical cells with respect to broadband sounds by presenting sounds with a spectro-temporal envelope of constant spectral density and angular frequency for several seconds. However, ...
متن کاملContrast tuning in auditory cortex.
The acoustic features useful for converting auditory information into perceived objects are poorly understood. Although auditory cortex neurons have been described as being narrowly tuned and preferentially responsive to narrowband signals, naturally occurring sounds are generally wideband with unique spectral energy profiles. Through the use of parametric wideband acoustic stimuli, we found th...
متن کاملEmergence of Tuning to Natural Stimulus Statistics along the Central Auditory Pathway
We have previously shown that neurons in primary auditory cortex (A1) of anaesthetized (ketamine/medetomidine) ferrets respond more strongly and reliably to dynamic stimuli whose statistics follow "natural" 1/f dynamics than to stimuli exhibiting pitch and amplitude modulations that are faster (1/f(0.5)) or slower (1/f(2)) than 1/f. To investigate where along the central auditory pathway this 1...
