Spatial organization of multisensory responses in temporal association cortex.
Neurons in sensory cortices are often topographically organized according to their response preferences. We here show that such an organization of response preferences also exists in multisensory association cortex. Using electrophysiological mappings, we probed the modality preference to auditory and visual stimuli of neurons in the superior temporal association cortex of nonhuman primates. We...
متن کاملTwo distinct regions of secondary somatosensory cortex in the rat: topographical organization and multisensory responses.
In rodents, as in other species, regions of secondary somatosensory cortex (SII) may be distinguished from primary cortex (SI) both anatomically and electrophysiologically. However, the number of rodent SII subregions, their somatotopic organization, and their function are poorly understood. The presence of multisensory responsive neurons in some areas of SII suggests that one of its roles may ...
متن کاملSpatial receptive field organization of multisensory neurons and its impact on multisensory interactions.
Previous work has established that the spatial receptive fields (SRFs) of multisensory neurons in the cerebral cortex are strikingly heterogeneous, and that SRF architecture plays an important deterministic role in sensory responsiveness and multisensory integrative capacities. The initial part of this contribution serves to review these findings detailing the key features of SRF organization i...
متن کاملRapidly acquired multisensory association in the olfactory cortex
BACKGROUND The formation of an odor percept in humans is strongly associated with visual information. However, much less is known about the roles of learning and memory in shaping the multisensory nature of odor representations in the brain. METHOD The dynamics of odor and visual association in olfaction was investigated using three functional magnetic resonance imaging (fMRI) paradigms. In t...
متن کاملSpatial organization of neuronal population responses in layer 2/3 of rat barrel cortex.
Individual pyramidal neurons of neocortex show sparse and variable responses to sensory stimuli in vivo. It has remained unclear how this variability extends to population responses on a trial-to-trial basis. Here, we characterized single-neuron and population responses to whisker stimulation in layer 2/3 (L2/3) of identified columns in rat barrel cortex using in vivo two-photon calcium imaging...
