Description

This experiment expores the link between neuroplasticity and induced hallucinations. With the stroboscopic stimulation model, we induced frequency-dependent hallucination. Using EEG, we compared visually-evoked potentials (VEPs) from occipital electrode recordings. We used these VEP recordings as an indicator of attentional allocation and responsiveness to the stimulus. We are contributing to the body of work involving halllucination-inducing models by exploring the relationship to plasticity.
