Mechanisms of adaptation in human auditory cortex.
This study investigates the temporal properties of adaptation in the late auditory-evoked potentials in humans. The results are used to make inferences about the mechanisms of adaptation in human auditory cortex. The first experiment measured adaptation by single adapters as a combined function of the adapter duration and the stimulus onset asynchrony (SOA) and interstimulus interval (ISI) betw...
متن کاملNeuronal Adaptation in Cat Auditory Cortex
Neuronal adaptation – the decline over time of neuronal responses to sensory stimuli – is ubiquitous in all sensory brain areas, especially in the cortex. Adaptation has been implicated in several functional roles, mostly related to the ability of adaptation to improve the neural coding of new incoming stimuli, given a certain stimulus ensemble. Thus, adaptation has been shown to optimize infor...

متن کاملNeural coding strategies in auditory cortex.
In contrast to the visual system, the auditory system has longer subcortical pathways and more spiking synapses between the peripheral receptors and the cortex. This unique organization reflects the needs of the auditory system to extract behaviorally relevant information from a complex acoustic environment using strategies different from those used by other sensory systems. The neural represen...
متن کاملPrior expectation mediates neural adaptation to repeated sounds in the auditory cortex: an MEG study.
Repetition suppression, the phenomenon that the second presentation of a stimulus attenuates neural activity, is typically viewed as an automatic consequence of repeated stimulus presentation. However, a recent neuroimaging study has suggested that repetition suppression may be driven by top-down expectations. Here we examined whether and when repetition suppression can be modulated by top-down...
