Summary of the VLPFC population responses to unimodal and multisensory stimulus conditions. a, A total of 387 neurons that responded to audiovisual vocalization stimuli and were categorized according to their responses based on a three-way ANOVA: 4% (16 of 387) of neurons responded to a unimodal auditory stimulus exclusively (black); 50% (194 of 387) responded to one or both of the unimodal visual conditions but not to auditory or multisensory conditions (white); a total of 177 of 387 (46%) neurons of the recorded population were responsive to multisensory stimuli with 7% of these (27 of 387; light gray) responding to both the auditory and visual unimodal conditions, which we termed a linear response, whereas the remaining nonlinear multisensory neurons (39% or 150 of 387; dark gray) had a significant interaction (AVs or AVm). b, The number of neurons that showed multisensory responses by stimulus conditions. Left to right, The number of neurons that responded to AVm, AVs, or both was 60, 51, and 39, respectively.
