fMRI data from macaques suggest that sounds with similar temporal characteristics activate neighbouring regions of auditory cortex, giving rise to a topographic map broadly analogous to that for sound frequencies.
The aged human auditory cortex shows preserved tonotopy, but temporal modulations are represented with a markedly broader tuning, highlighting decreased temporal selectivity as a hallmark of the aging auditory cortex.
Neurons can synchronize, supporting flexible communication among brain areas; closed-loop optogenetics allows the frequency and power of population oscillations to be dissociated, providing a tool to interrogate how networks couple.
Everyday soundscapes dynamically engage attention towards target sounds or salient ambient events, with both attentional forms engaging the same fronto-parietal network but in a push-pull competition for limited neural resources.
Physiological and behavioral analyses show that expression of cerebellar whisker learning can be mediated by increased simple spike activity, depending on LTP induction at parallel fiber to Purkinje cell synapses.
