Spatial factors determine the activity of multisensory neurons in cat superior colliculus.
The responses of a neuron to stimuli from one sensory modality can be profoundly influenced by inputs from other sensory modalities. The present experiments demonstrate that the nature and the magnitude of these multisensory interactions depend on the positions of the stimuli in relation to their respective receptive fields. The spatial rules governing these interactions underscore the significance of the alignment of sensory maps in the brain.
