“…We note that activations in the lower part of the inferior frontal gyrus (pars opercularis), overlapping with Broca's area (sometimes extending to the anterior insula; Dieterich et al, 2003), have not been described as vestibular cortex in animals. On the contrary, other authors found frontal activations more dorsally in the "dorsolateral prefrontal cortex" (Fasold et al, 2002), or in the middle and superior frontal gyri (Bense et al, 2001;Dieterich et al, 2003;Miyamoto et al, 2007;Stephan et al, 2005), that have been proposed to represent vestibular processing in the human FEF in relation to the control of saccades, smooth-pursuit eye movements and nystagmus (Blanke et al, 2000b;Blanke and Seeck, 2003;Paus, 1996;Petit et al, 1997). These potential homologies between oculomotor and vestibular function in human and non-human primates should be regarded with caution as there may be subtle interspecies differences in anatomico-functional organization between area 6 and 8 (Tehovnik et al, 2000).…”

“…An activation of the posterior intraparietal sulcus has been revealed by Miyamoto et al (2007) during otolithic stimulation, and by Suzuki et al (2001) during semicircular canals, suggesting a vestibular region in humans that is distinct from the more anterior human homologue of area 2v. Finally, vestibular stimulation also activated the lateral superior parietal lobule (human area 7) (Vitte et al, 1996), and medially the precuneus (Suzuki et al, 2001).…”

“…In humans, galvanic and caloric vestibular stimulation were also found to activate several frontal regions including the primary motor cortex (precentral gyrus), the premotor cortex, as well as the superior (BA 10/8), middle (BA 9/8/6) and inferior (areas 44 and 47) frontal gyri (Bense et al, 2001;Emri et al, 2003;Fasold et al, 2002;Lobel et al, 1998;Miyamoto et al, 2007). During galvanic vestibular stimulation, Lobel et al (1998) reported activation in the pars opercularis of the inferior frontal gyrus, and more dorsally in the inferior and medial frontal gyri (Fig.…”

The vestibular system provides the brain with sensory signals about three-dimensional head rotations and translations. These signals are important for postural and oculomotor control, as well as for spatial and bodily perception and cognition, and they are subtended by pathways running from the vestibular nuclei to the thalamus, cerebellum and the "vestibular cortex."The present review summarizes current knowledge on the anatomy of the thalamocortical vestibular system and discusses data from electrophysiology and neuroanatomy in animals by comparing them with data from neuroimagery and neurology in humans. Multiple thalamic nuclei are involved in vestibular processing, including the ventroposterior complex, the ventroanterior-ventrolateral complex, the intralaminar nuclei and the posterior nuclear group 2 0 1 1 ) 1 1 9 -1 4 6 Abbreviations: 3aHv, 3a-hand-vestibular area; 3aNv, 3a-neck-vestibular area; ASS, anterior suprasylvian cortex; DVN, descending vestibular nucleus; FEF, frontal eye fields; Ig, insula granularis; IL, intralaminar nuclei; LD, lateral dorsal nucleus; LGN, lateral geniculate nucleus; LP, lateral posterior nucleus; LVN, lateral vestibular nucleus; MGmc, medial geniculate nucleus, pars magnocellularis; MGN, medial geniculate nucleus; MIP, medial intraparietal area; MST, medial superior temporal area; MT, middle temporal area; MVN, medial vestibular nucleus; PIVC, parieto-insular vestibular cortex; PO, posterior group of the thalamus; Reipt, area retroinsularis pars parietalis; Ri, area retroinsularis; SGN, suprageniculate nucleus; SVN, superior vestibular nucleus; TPJ, temporo-parietal junction; VA, ventroanterior thalamic nucleus; Vim, nucleus ventralis intermedius; VIP R A I N R E S E A R C H R E V I E W S 6 7 (

Otolith inputs to pursuit neurons in the frontal eye fields of alert monkeys

The smooth-pursuit system must interact with the vestibular system to maintain the accuracy of eye movements in space during head movement. Maintenance of a target image on the foveae is required not only during head rotation which activates primarily semi-circular canals but also during head translation which activates otolith organs. The caudal part of the frontal eye Welds (FEF) contains pursuit neurons. The majority of them receive vestibular inputs induced by whole body rotation. However, it has not been tested whether FEF pursuit neurons receive otolith inputs. In the present study, we Wrst classiWed FEF pursuit neurons as belonging to one of three groups (vergence + fronto-parallel pursuit, vergence only, fronto-parallel pursuit only) based on their responses during fronto-parallel pursuit and mid-sagittal vergence-pursuit. We, then, tested discharge modulation of these neurons during fore/aft and/or right/left translation by passively moving the whole body sinusoidally at 0.33 Hz ( §10 cm, peak velocity 19 cm/s; 0.04g). The majority of FEF pursuit neurons in all three groups were activated by fore/aft and right/left translation without a target in complete darkness. There was no correlation between the magnitude of discharge modulation and translational vestibulo-ocular reXex (VOR). Preferred directions of translational responses were distributed nearly evenly in front of the monkeys. Discharge modulation was also observed when a target moved together with whole body, requiring the monkeys to cancel the translational VOR. These results indicate that the discharge modulation of FEF pursuit neurons during whole body translation reXected otolith inputs.

Susceptibility to motion sickness varies greatly across individuals. However, the neural mechanisms underlying this susceptibility remain largely unclear. To address this gap, the current study aimed to identify the neural correlates of motion sickness susceptibility using multimodal MRI. First, we compared resting-state functional connectivity between healthy individuals who were highly susceptible to motion sickness (N = 36) and age/sex-matched controls who showed low susceptibility (N = 36).Seed-based analysis revealed between-group differences in functional connectivity of core vestibular regions in the left posterior Sylvian fissure. A data-driven approach using intrinsic connectivity contrast found greater network centrality of the left intraparietal sulcus in high-rather than in low-susceptible individuals. Moreover, exploratory structural connectivity analysis uncovered an association between motion sickness susceptibility and white matter integrity in the left inferior frontooccipital fasciculus. Taken together, our data indicate left parietal involvement in motion sickness susceptibility.
