Visuospatial Properties of Ventral Premotor Cortex

Abstract: In macaque ventral premotor cortex, we recorded the activity of neurons that responded to both visual and tactile stimuli. For these bimodal cells, the visual receptive field extended from the tactile receptive field into the adjacent space. Their tactile receptive fields were organized topographically, with the arms represented medially, the face represented in the middle, and the inside of the mouth represented laterally. For many neurons, both the visual and tactile responses were directionally selective, a… Show more

“…Critically, these reaction times within the approximated PPS are significantly faster than reaction times to unimodal tactile stimulation (i.e., when no visual stimulus is presented in conjunction with the tactile stimulus). Notably, when the stimulus instead recedes from the body, this sigmoidal relationship (usually) disappears (Canzoneri et al 2012;Teneggi et al 2013;Noel et al 2015;Serino et al 2015).This aligns with the aforementioned neurophysiological studies that have shown that neurons in the PPS network preferentially respond to stimuli approaching (in contrast to receding from) the body (Colby et al 1993;Graziano and Gross 1995;Fogassi et al 1996;Graziano et al 1997;Duhamel et al 1998).…”

“…For instance, one might swat an approaching (buzzing) fly away from his face, or retract the foot from an oncoming wave on the beach shore. Intriguingly, early neurophysiological studies in non-human primates have shown that there are special fronto-parietal neurons that respond not only to an object touching a body part but also the presence of an object near that same body part (Graziano et al 1994(Graziano et al , 1997Fogassi et al 1996;Graziano and Cooke 2006). These neurons are bi-and tri-modal in nature; their tactile receptive fields overlap with visual and/or auditory receptive fields that extend into space around the body.…”
