ungerleider and mishkin describe which functions of the vision system
Two-streams hypothesis In 1982 Ungerleider and Mishkin distinguished the dorsal and ventral streams, as processing spatial and visual features respectively, from their lesion studies of monkeys â€“ proposing the original where vs what distinction.[7] Though this framework was superseded by that of Milner & Goodale, it remains influential.[8]
Ciliary body The ciliary body has three functions: accommodation, aqueous humor production and resorption, and maintenance of the lens zonules for the purpose of anchoring the lens in place.
