Fig. 5. SC RFs and responses after the development.
Responses in a simulated mature SC neuron to different spatial configurations of modality-specific (only visual, panel a, only auditory, panel b) and cross-modal stimuli (panel c). Note the contraction of receptive fields compared to those shown in Fig.3. In this neuron the RFs are clearly in spatial register and overlapped each other. In panel c the neuron shows its integrative capabilities: the multisensory enhancement is produced by concordant cross-modal stimuli and it can be observed throughout the entire extent of the overlapping portions of the RFs.
