title

Rehabilitation of Hemianopia Rescues Multisensory Integration and Feature Discrimination

author

Bean, Naomi Lynn

abstract

Hemianopia is a blindness in one hemifield of space caused by damage to visual cortex on the opposite side of the brain. This blindness persists despite other visual areas being physically spared from the cortical insult. One such area is the midbrain superior colliculus (SC). Neurons in the deep layers of the SC receive inputs for multiple sensory modalities: visual, auditory, and somatosensory. When stimuli from two of these modalities (cross-modal stimuli) are presented in spatiotemporal concordance, they are integrated and their combined signal enhanced (multisensory enhancement). However, these neurons in the deep layers of the SC are unable to respond to visual stimuli under hemianopia.
