As a general rule, the supine position leads to decreased performance in visual vertical judgments and tactile perception probably because vestibular otolith receptors and muscular proprioceptive receptors are less sensitive to gravity in this specific orientation. By contrast, in patients with unilateral brain damage (neglect and extinction patients), the supine position reduces spatial symptoms during visual vertical judgments, exploration of the extrapersonal space (line bisection) and personal space (tactile perception). We also highlight evidence suggesting that body position influences bodily self-consciousness, such as embodiment and the first-person perspective, concluding by showing that artificial vestibular stimulation allows to manipulate bodily self-consciousness.
