Cutaneous, proprioceptive, and multimodal responses in S1 (adapted from Kim et al. 2015). A: population distributions of unimodal and multimodal neurons across S1. B, left: linear multimodal neuron whose responses are modulated by hand posture before cutaneous stimulation. B, right: cutaneous stimulation caused uniform increases in response rates over all hand postures. C: multimodal nonlinear neuron whose responses are modulated by hand posture before cutaneous stimulation (left) and by cutaneous stimulation (right). The response patterns over postures differ between the baseline and cutaneous conditions.
