What is the Parieto insular cortex?
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, and visual target rotations.
What is the function of the vestibular cortex?
The two major cortical functions of the vestibular system are spatial orientation and self-motion perception. These functions, however, are not exclusively vestibular; they also rely on visual and somatosensory input.
What is the primary vestibular cortex?
Vestibular cortex is the portion of the cerebrum which responds to input from the vestibular system. The location is not well defined, but some research indicates a right hemisphere dominance. Lesions of the vestibular nucleus impair function.
Is vestibular information is processed in the parietal lobe?
Based on our findings and those of the recent literature, we suggest that the parietal cortex constitutes a unique cortical region involved in high-ordered multimodal transformation of inertial vestibular signals including the updating of the visual space during body displacements.
What is the main function of the insula?
It plays a role in a variety of homeostatic functions related to basic survival needs, such as taste, visceral sensation, and autonomic control. The insula controls autonomic functions through the regulation of the sympathetic and parasympathetic systems. It has a role in regulating the immune system.
Why is the insula important?
Depending on whom you ask, the insula is involved in pain, love, emotion, craving, addiction, the enjoyment of music, or even the tasting of wine. Damasio suggested that the insula plays an important role in the processing of these bodily sensations so they may be used to influence decision making.
Where is the vestibular cortex?
The Parietal Lobe Its core region, the parietoinsular vestibular cortex (PIVC), is located in the posterior insula and retroinsular region and includes the parietal operculum. The entire network is multisensory (in particular, vestibular, visual, and somatosensory).
How does vestibular information reach the cortex?
Four major pathways have been hypothesized to transmit vestibular information to the vestibular cortex: (1) the vestibulo-thalamo-cortical pathway, which probably transmits spatial information about the environment via the parietal, entorhinal and perirhinal cortices to the hippocampus and is associated with spatial …

What is the insula of the brain?
The insula is a small region of the cerebral cortex located deep within the lateral sulcus, which is a large fissure that separates the frontal and parietal lobes from the temporal lobe.
What is the insula function?
Where is the parieto insular vestibular cortex located?
Here, we review the structure and function of a core region in the vestibular cortex of humans that is located in the midposterior Sylvian fissure and referred to as the parieto-insular vestibular cortex (PIVC).
Which is the homologue of the vestibular cortex?
The vestibular cortex. Its locations, functions, and disorders Evidence is presented that the multisensory parieto-insular cortex is the human homologue of the parieto-insular vestibular cortex (PIVC) in the monkey and is involved in the perception of verticality and self-motion.
Where are vestibular cues projected in the brain?
Vestibular cues are projected from the semicircular canals and the otoliths via the vestibular portion of the VIII cranial nerve to the vestibular nuclei in the brain stem ( Barmack 2003; Büttner-Ennever 1992; Highstein and Holstein 2006; Korte 1979 ). Further projections are sent to the cerebellum ( Hitier et al. 2014; Korte and Mugnaini 1979 ).
