Quiz answers

Quiz 1: (1) retinotopic means topographically organized in a manner that follows the organization of the retina; by extension, it implies that neighboring stimuli in visual space will excite neighboring neurons in a retinotopic map. Experiment: show a pattern to a monkey, inject radioactive glucose, take out monkey V1, flatten it on a photographic plate, see how (a deformed version of) the pattern becomes impressed onto the photographic plate (Tootell et al., 1982). [Slide 47 of lecture 02] (2) Planning, emotion, judgement, motor control, speech, memory, cognitive tasks, attention, etc. (include at least two) [Slides 22, 26, 27, 32]

Quiz 2: (1) Source localization and source separation [slide 8 of lecture 03]. Also accepted for 1 point if you said that it was hard to implant or setup. (2) Increase in oxygenation due to overshoot of vascular response to increased demand in oxygen due to neuronal activity [slide 53].

Quiz 3: (1) Region of retina where photoreceptors are most densely packed [slides 28-30 of lecture 04]. (2) No because of limitation due to blurring in the optics. We saw that actual density of receptors matches those optical limitations (according to sampling theorem), so adding more receptors would not help much [slide 35].
