White Board Series (Audio Version): Corollary Discharge & Visual Processing

Video: https://www.youtube.com/watch?v=ipZ6eLgpArA

Ever wonder how the brain predicts what your eyes will see before you even move? In this episode, we uncover the secret of corollary discharge, the hidden “prediction machine” behind vision, eye movements, & sensory processing. Learn why Autistic individuals may appear inward-focused, how sensory overload hijacks attention, & the surprising ways the brain turns these challenges into high-speed learning superpowers.

00:00 Corollary discharge & the autistic phenotype Kickoff with corollary discharge, prediction machines, & sensory processing in autism

02:03 – Corollary Discharge & Vision, the brain predicts movement and sensory input; visual cortex & heightened perception.

03:07 – Pathway 1: Retina → Superior Colliculus → FEF → Parietal → LG → V2 Red pathway for eye movement prep; feedback loops, thalamic relay, & sensory integration explained.

10:54 – Pathway 2: Retina → Lateral Geniculate → V1 → Visual Cortex → V2 Green pathway handling 85–90% of projections; raw sensory info & sensation-to-perception mapping.

12:36 – Eye Movement & Cranial Nerves Cranial nerves 3, 4, 6 control eye alignment & attention orientation; precision timing explained.

17:57 – Sensory Overload & Misunderstood Attention in Autism; inward-focused, overwhelm, & social misinterpretations.

20:40 – Internal Benefits & Learning in Autism, high-speed info processing, “fire together, wire together.”

24:50 – Sensation - Perception Prediction
