Visual-auditory spatial processing in auditory cortical neurons.
Neurons responsive to visual stimulation have now been described in the auditory cortex of various species, but their functions are largely unknown. Here we investigate the auditory and visual spatial sensitivity of neurons recorded in 5 different primary and non-primary auditory cortical areas of the ferret. We quantified the spatial tuning of neurons by measuring the responses to stimuli pres...
متن کاملCompromise of auditory cortical tuning and topography after cross-modal invasion by visual inputs.
Brain damage resulting in loss of sensory stimulation can induce reorganization of sensory maps in cerebral cortex. Previous research on recovery from brain damage has focused primarily on adaptive plasticity within the affected modality. Less attention has been paid to maladaptive plasticity that may arise as a result of ectopic innervation from other modalities. Using ferrets in which neonata...
متن کاملCompetition and convergence between auditory and cross - modal visual inputs to 12 primary auditory cortical areas
42 Sensory neocortex is capable of considerable plasticity after sensory deprivation or damage to 43 input pathways, especially early in development. Although plasticity can often be restorative, 44 sometimes novel, ectopic inputs invade the affected cortical area. Invading inputs from other 45 sensory modalities may compromise the original function or even take over, imposing a new 46 function...

متن کاملMultisensory processing in "unimodal" neurons: cross-modal subthreshold auditory effects in cat extrastriate visual cortex.
Historically, the study of multisensory processing has examined the function of the definitive neuron type, the bimodal neuron. These neurons are excited by inputs from more than one sensory modality, and when multisensory stimuli are present, they can integrate their responses in a predictable manner. However, recent studies have revealed that multisensory processing in the cortex is not restr...
