Dark-rearing prevents the normal development of multisensory integration and the normal contraction of SC RFs. Illustrative receptive field overlap is shown for one neuron (upper) as is its lack of multisensory integration (8% change, NS, t-test). Population analyses showed that although multisensory neurons were common in these animals (pie chart, lower left) evidence of multisensory integration was very rare (4% vs. 81% in normals). The effect of dark rearing on RF size (they contract very little during development) is shown in the lower right where visual, auditory and somatosensory RF sizes are compared to those in normal populations.
