White Board Series: Corollary Discharge and Visual Processing

Описание: 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, and sensory processing. Learn why Autistic individuals may appear inward-focused, how sensory overload hijacks attention, and the surprising ways the brain turns these challenges into high-speed learning superpowers.

Autism means "autos" which means "self."

00:00 — Corollary discharge & the autistic phenotype
Kickoff with corollary discharge, prediction machines, and sensory processing in autism; Four Core Autistic Phenotypes
Sensory processing, speech/language, GI issues, and circadian rhythm; mitochondria as upstream.
02:03 – Corollary Discharge & Vision Overview
How the brain predicts movement and sensory input; visual cortex and heightened perception in autism.
03:07 – Pathway 1: Retina → Superior Colliculus → FEF → Parietal → LG → V2
Red pathway for eye movement prep; feedback loops, thalamic relay, and sensory integration explained.
10:54 – Pathway 2: Retina → Lateral Geniculate → V1 → Visual Cortex → V2
Green pathway handling 85–90% of projections; raw sensory info and sensation-to-perception mapping.
12:36 – Eye Movement & Cranial Nerves
Cranial nerves 3, 4, 6 control eye alignment and attention orientation; precision timing explained.
17:57 – Sensory Overload & Misunderstood Attention in Autism
Why autistic individuals appear inward-focused; biases, overwhelm, and social misinterpretations.
20:40 – Internal Benefits & Learning in Autism
Accelerated learning, high-speed info processing, connection strengthening, “fire together, wire together.”
24:50 – Sensation to Perception
Prediction, sensation-to-perception, and neuroplasticity as keys to understanding autistic experience.
26:05 — Evidence, timing windows & bridge to reading
What supports the model and why reading is the next stop.
