What does a neuron learn from multisensory experience?

abstract：:We presented optic flow and real movement heading stimuli while recording MSTd neuronal activity. Monkeys were alternately engaged in three tasks: visual detection of optic flow heading perturbations, vestibular detection of real movement heading perturbations, and auditory detection of brief tones. Push-button RTs we...
