Penfield's phenomena

Penfield’s phenomena refer to the vivid sensations or perceptions that can occur when specific areas of the brain's cortex are stimulated during surgery. Penfield, a neurosurgeon, discovered that stimulating certain brain regions could evoke experiences like tingling, visual images, or even recall of memories. These phenomena help map the brain's functions and explain how different parts of the brain are linked to sensory experiences, emotions, and memories. Essentially, they reveal how our brains create our perception of the world, and stimulating these areas can produce controlled, temporary sensory or perceptual experiences.
