What does it really mean to see with the mind’s eye?In this conversation, neurologist and consciousness researcher Professor Adam Zeman (Cognitive & Behavioural Neurologist, University of Exeter) joins Dr Tevin Naidu on Mind-Body Solution to explore the mysterious link between imagination, memory, and perception - and what happens when the mind’s eye goes dark.Zeman coined the term aphantasia, the inability to form mental images, and has spent decades studying how imagination shapes our sense of self and consciousness. Together, we discuss:- The neuroscience of mental imagery and its vividness- What aphantasia and hyperphantasia reveal about the brain-mind interface- Imagination’s evolutionary and social roles- How disorders of imagery illuminate the nature of consciousness- Why defining "inner experience" remains one of science's deepest puzzlesTIMESTAMPS:(00:00) - Introduction: Why imagination matters and the four big ideas(02:14) - What do we mean by “imagination”?
