TLDR
The results show that vestibular information can influence higher-order cognitive processes, such as the body schema and mental imagery, as well as top-down imagined whole-body rotations, including the precuneus and tempero-parietal junction.Abstract:
The body schema is a key component in accomplishing egocentric mental transformations, which rely on bodily reference frames. These reference frames are based on a plurality of different cognitive and sensory cues among which the vestibular system plays a prominent role. We investigated whether a bottom-up influence of vestibular stimulation modulates the ability to perform egocentric mental transformations. Participants were significantly faster to make correct spatial judgments during vestibular stimulation as compared to sham stimulation. Interestingly, no such effects were found for mental transformation of hand stimuli or during mental transformations of letters, thus showing a selective influence of vestibular stimulation on the rotation of whole-body reference frames. Furthermore, we found an interaction with the angle of rotation and vestibular stimulation demonstrating an increase in facilitation during mental body rotations in a direction congruent with rightward vestibular afferents. We propose that facilitation reflects a convergence in shared brain areas that process bottom-up vestibular signals and top-down imagined whole-body rotations, including the precuneus and tempero-parietal junction. Ultimately, our results show that vestibular information can influence higher-order cognitive processes, such as the body schema and mental imagery.read more

TL;DR: Although the findings from the subjective reports confirmed the previous findings of virtual OBEs, no significant difference between the two postures was found for body ownership and the findings of the current study make further contributions to the understanding of both the vestibular system and time perception during O BEs.

TL;DR: Current research on the pathophysiology of cognitive-vestibular interactions and its emerging clinical relevance is reviewed and Physicians should be aware of emerging data supporting the presence of cognitive deficits in patients with vestibular disorders.

TL;DR: The results suggest that hypoperfusion in the frontal and temporal cortices might be reflecting the negative impact of dizziness in MCI patients.

The Effect of Cognitive Tasks on the Ocular Vestibular Evoked Myogenic Potentials in Healthy People.
TL;DR: The results suggest that an augmented cognitive load causes an alteration in the oVEMPs; therefore, it is suggested that the structures associated with the cognitive processing are connected with the vestibular system in the brain.
The impact of retinal size on mental transformations in imagery: Rotation, synthesis, combination
TL;DR: The obtained results support the analogousness of the mental world to the world in which the authors live, as this impact significantly influenced the effectiveness of all three mental operations.

Temporal and kinematic properties of motor behavior reflected in mentally simulated action.
TL;DR: Related perceptual, motor, and cognitive performances were examined to reveal the accuracy of the properties of action spontaneously represented when mentally simulating moving one's hand, and suggest that sensorimotor structures support mental simulations of actions.

TL;DR: Converging evidence from animal and human studies suggests that the primate brain constructs various body-part-centred representations of space, based on the integration of visual, tactile and proprioceptive information.

TL;DR: It is suggested that the temporoparietal junction is a crucial structure for the conscious experience of the normal self, mediating spatial unity of self and body, and also suggest that impaired processing at the TPJ may lead to pathological selves such as OBEs.

TL;DR: This PET study showed for the first time that cortical and subcortical activation by vestibular caloric stimulation depends on the handedness of the subjects and on the side of the stimulated ear.

TL;DR: The widespread Vestibular projections to the multimodal human PIVC, somatosensory cortex, area MST, intraparietal sulcus and hippocampus explain the large influence of vestibular signals on self-motion perception, spatial navigation, internal models of gravity, one's body perception and bodily self-consciousness.
