Indirect bottom–up multisensory input from the SC to the cortex: Almost all sensory inputs (visual, auditory, somatosensory, proprioceptive and nociceptive) converge at the Deep SC. The visual input from the superficial SC is the most massive and leads to the correspondence of the rest (somatosensory, auditory, etc.) Several thalamic nuclei receive deep SC input to further reach the cortex.
