Throughout the year, I summarised my class notes on this flash sheet and actually used this to revise for my exam. I got a first so I'd say it worked! Hope it helps.
Specialisation Perception & Action
What is it?
V1 & V2 – basic visual processing Ventral Stream
Perception – experiences
V3 – form perception resulting from stimulation of senses

V4 – colour vs what’s background
