Visual task enhances spatial selectivity in the human auditory cortex
The auditory cortex represents spatial locations differently from other sensory modalities. While visual and tactile cortices utilize topographical space maps, for audition no such cortical map has been found. Instead, auditory cortical neurons have wide spatial receptive fields and together they form a population rate code of sound source location. Recent studies have shown that this code is m...
متن کاملSpatial sensitivity in field PAF of cat auditory cortex.
We compared the spatial tuning properties of neurons in two fields [primary auditory cortex (A1) and posterior auditory field (PAF)] of cat auditory cortex. Broadband noise bursts of 80-ms duration were presented from loudspeakers throughout 360 degrees in the horizontal plane (azimuth) or 260 degrees in the vertical median plane (elevation). Sound levels varied from 20 to 40 dB above units' th...
متن کاملCorrelates of Auditory Attention and Task Performance in Primary Auditory and Prefrontal Cortex
Abstract Auditory experience can reshape cortical maps and transform receptive field properties of neurons in the auditory cortex of the adult animal in a manner that depends on the behavioral context and the acoustic features of the stimuli. This has been shown in physiological and behavioral experiments, in which auditory cortical cells underwent rapid, context-dependent changes of their rece...
متن کاملMotivation sharpens exogenous spatial attention.
Although both attention and motivation affect behavior, how these 2 systems interact is currently unknown. To address this question, 2 experiments were conducted in which participants performed a spatially cued forced-choice localization task under varying levels of motivation. Participants were asked to indicate the location of a peripherally cued target while ignoring a distracter. Motivation...
