Visuo-vestibular integration is crucial for locomotion, yet the cortical mechanisms involved remain poorly understood. We combined binaural monopolar galvanic vestibular stimulation (GVS) and functional magnetic resonance imaging (fMRI) to characterize the cortical networks activated during antero-posterior and lateral stimulations in humans. We focused on functional areas that selectively respond to egomotion-consistent optic flow patterns: the human middle temporal complex (hMT+), V6, the ventral intraparietal (VIP) area, the cingulate sulcus visual (CSv) area and the posterior insular cortex (PIC). Areas hMT+, CSv, and PIC were equivalently responsive during lateral and anteroposterior GVS while areas VIP and V6 were highly activated during antero-posterior GVS, but remained silent during lateral GVS. Using psychophysiological interaction (PPI) analyses, we confirmed that a cortical network including areas V6 and VIP is engaged during antero-posterior GVS. Our results suggest that V6 and VIP play a specific role in processing multisensory signals specific to locomotion during navigation.

“…The achievement of gross motor milestones can be attributed to the active participation of the child in learning the skills through facilitation by physiotherapist based on principles of NDT. SI approach must have contributed to improving his balance [ 9 ]. Vestibular stimulation helps in visual system facilitation through vestibular-visual interaction [ 10 ].…”

Encephalitis refers to inflammation of the brain parenchyma. It is potentially life-threatening with the highest incidence and severity in younger children. Febrile infection-related epilepsy syndrome (FIRES) is a condition, in which a child develops a nonspecific febrile illness that may not persist when the initial seizure activity begins. However, an electroencephalogram (EEG) shows that the child is in status epilepticus. We report the case of a five-year-old male who presented with difficulty to maintain sitting posture, and inability to stand and walk without support, following viral encephalitis at the age of one year. He had motor, visual, speech and cognitive impairment along with a seizure disorder. The physiotherapy interventions including neurodevelopmental treatment (NDT) and sensory integration (SI) helped in regaining locomotion ability in the child. The study aims to assess the impact of physiotherapy interventions on regaining locomotor ability in a child with FIRES following infective encephalitis.

“…Albeit this is compatible with a vestibular stimulation, the direction of this illusion is unusual for a bilateral montage. Displacements along the anterior-posterior axis may be expected for antero-posterior montages (Aedo-Jury, Cottereau, Celebrini, & Severac Cauquil, 2019), rather than for lateral ones. This illusion may have been genuinely prompted by the (mixed) vestibular signals that participants experienced, or could simply reflect difficulties in accurately discriminating or recall (after the stimulation) the sensations experienced.…”

Somatic inputs originating from bioregulatory processes can guide cognition and behavior.One such bodily signal, mostly overlooked so far, is represented by visuo-vestibular coupling and its alteration, which in extreme cases may result in motion sickness. We argued that the inherently perturbed interoceptive state that follows can be a powerful determinant of human motivated behavior, resulting in a blunted response to appetitive stimuli and an exaggerated response to noxious ones. We sought to assess such differential impact of visuo-vestibular mismatches on value through a task involving conflict monitoring. We therefore administered to 42 healthy participants a modified version of the Flankers task, in which distractors (arrows, pointing in either a congruent or incongruent direction) signaled the availability of monetary incentives (gains, losses, or neutral trials). While performing the task, participants received either galvanic vestibular stimulation (GVS), or sham stimulation. We have found impaired behavioral performances when value, which was attached to task-irrelevant information, was at stake. Gains and losses, interestingly, dissociated, and only the latter caused enhanced interference costs in the task, suggesting that negative incentives may be more effective in capturing human attention than positive ones. Finally, we have found some weak evidence for GVS to further increase the processing of losses, as suggested by even larger interference costs in this condition. Results were, however, overall ambiguous, and suggest that much more research is needed to better understand the link between the vestibular system and motivation. Highlights Visuo-Vestibular mismatches may be important somatic markers affecting the evaluation of reinforcers; When attached to distractors, value information impairs behavioral performance for the task at hand;  Trials in which potential losses were at stake were associated with larger interference costs arising from conflicting information between the target and the flankers;
