Psychedelic substances may enhance creativity by inducing cognitive flexibility, allowing a wider range of associations and possibilities to be explored. Virtual Reality can simulate psychedelic perceptual and cognitive effects without associated risks. The Bayesian brain approach, rooted in predictive coding, offers a framework for understanding how psychedelic hallucinations affect cognition. Cognitive flexibility is linked to creative thinking and depends on prefrontal cortex and networks supporting executive functions, memory, attention, and spontaneous thought. Aging and Mild Cognitive Impairment involve declines in creative processing and divergent thinking. The paper suggests that VR-induced psychedelic hallucinations may help optimize the balance between top-down expectations and bottom-up sensory information, potentially maintaining cognitive functions and preventing pathological conditions in aging.
