PSYC 312 · Week 7 · Chapter 5

Vision

From light → retina → color coding → visual cortex → object and face recognition.

Week 7

Big picture

LIGHT → RETINAL RECEPTORS → GANGLION CELLS / OPTIC NERVE → LGN → V1 → LATER VISUAL AREAS → WHAT / ACTION STREAMS

🔗 Connections backward: Week 1 gave you receptors, graded potentials, neurons, axons and the CNS. Week 3 gave you membrane potential. Week 5–6 located the occipital lobe, LGN→V1 pathway, cortical maps and fMRI. Chapter 5 now follows one sensory system all the way from physical light to perception.

Study it in this order

1 · Eye + retina

Transduction → optic nerve → blind spot → fovea/periphery.

2 · Receptors + color

Rods/cones → photopigments → wavelength → S/M/L cones.

3 · Color theories

Trichromatic → deficiencies → opponent process → Retinex/context.

4 · Brain

LGN → V1/V2 → retinotopic maps → dorsal/ventral streams → recognition.

Memory line: RECEIVE LIGHT → CODE IT → COMPARE IT → MAP IT → RECOGNIZE / ACT.

Teach → Understand → Connect
