Reciprocal inhibitory visual-vestibular interaction. Visual motion stimulation deactivates the parieto-insular vestibular cortex.
The vestibular system--a sensor of head accelerations--cannot detect self-motion at constant velocity and thus requires supplementary visual information. The perception of self-motion during constant velocity movement is completely dependent on visually induced vection. This can be linear vection or circular vection (CV). CV is induced by large-field visual motion stimulation during which the s...
متن کاملSensory convergence in the parieto-insular vestibular cortex.
Vestibular signals are pervasive throughout the central nervous system, including the cortex, where they likely play different roles than they do in the better studied brainstem. Little is known about the parieto-insular vestibular cortex (PIVC), an area of the cortex with prominent vestibular inputs. Neural activity was recorded in the PIVC of rhesus macaques during combinations of head, body,...
متن کاملVestibular and Visual Responses in Human Posterior Insular 13 Cortex
36 The central hub of the cortical vestibular network in humans is likely localized in the region 37 of posterior lateral sulcus. An area characterized by responsiveness to visual motion has 38 previously been described at a similar location and named posterior insular cortex (PIC). 39 Currently it is not known whether PIC processes vestibular information as well. We localized 40 PIC using visu...

متن کاملMacaque parieto-insular vestibular cortex: responses to self-motion and optic flow.
The parieto-insular vestibular cortex (PIVC) is thought to contain an important representation of vestibular information. Here we describe responses of macaque PIVC neurons to three-dimensional (3D) vestibular and optic flow stimulation. We found robust vestibular responses to both translational and rotational stimuli in the retroinsular (Ri) and adjacent secondary somatosensory (S2) cortices. ...
