Cybersickness is a major barrier to the adoption of virtual reality (VR), yet its underlying neurophysiological mechanisms remain poorly understood. This study investigated whether vestibulomotor responses, quantified using coherence and gain between electrical vestibular stimulation (EVS) and mediolateral centre-of-pressure (ML-CoP) responses, are associated with susceptibility to cybersickness. Thirty-eight healthy young adults (21 females, 17 males) completed a standing VR rollercoaster task while receiving continuous stochastic EVS (0–25 Hz; ±4.5 mA), with ML-CoP responses measured using a force plate. Cybersickness was assessed using the Fast Motion Sickness Scale (FMS), and participants were classified as non-sick (FMS
