Among the components of the ANS (Autonomic Nervous System), electrodermal activity variations (EDA) are less involved in self-motion. However, from neuroanatomical point of view, EDA variations are essentially modulated by sympathetic endings that are interconnected with the vestibular system. The aim of the present study was to analyse the latencies for reporting vertical self-motion (upward and downward) and the variations of electrodermal activity in healthy adults (17 men and 18 women aged 22 years old on average; sd 1 year and 2 month) when they were visually exposed to an experimental 3D environment via a head mounted display (HMD). The results revealed that the otolithic saccular maculae contribute differently to latencies and electrodermal activations. When self-motion was towards earth gravity, latencies and electrodermal activity were shorter in downward self-motion than in upward self-motion. We suggest that a top-down organisation connected with the visuo-otolithic information along the vertical axis, which essentially contributes to self-position, equilibrium and body-consciousness, could provide a neuromorphic model to improve space location and representation of humanoid robots.
