Brain Activity in Imagination Overlaps with Perception in High-Level Areas

Researchers found that imagining sights and sounds activates high-level brain areas that process multiple senses, rather than sense-specific regions. The study used MRI scans on participants imagining various scenes and sounds. Results were published March 31 in the journal Neuro…

Study Identifies Similar Brain Processes for Visual Perception and Mental Imagery

A recent study shows that the brain activates the same neural processes when viewing an object and when imagining it. These processes resemble those used by artificial intelligence systems to generate images. The findings provide insights into human cognition and AI mechanisms.
