d) How is visible info ordered throughout propagation in the visible pathway. How is it organized in the visible cortex? (/1.5)
e) A affected person can describe a espresso mug that’s in entrance of them, however they’re having hassle reaching and greedy the mug. What viusal stream (dorsal or ventral) do you suppose this affected person has injury in and why? Describe the space(s)/construction(s) in that stream that are probably additionally broken. (/zero.5)
f) Your buddy thinks they’ve a concussion, they’re interested by what mind buildings could be impacted by their concussion and what the scientific penalties could be. Describe the trigger of delicate traumatic mind damage and ensuing signs (/zero.75)
This fall.
