Version AM-KEY: Page 1 of 12 Name:……… KEY ………. ID:………………………………. For short-answer and fill-in-the-blank questions: correct/accepted answers are in red , with added answers in bold . Answers that will not be accepted and my explanations are in green . I did not quote queries about the answer key verbatim, but I did my best to provide responses that addressed every query that I received on the noteboard or by email. 1. What causes the blind spot of the eye? It is the point where the axons of the retinal ganglion cells leave the eye, so there are no photoreceptors Also accepted: Absence of photoreceptors at that location on the retina, optic nerve exiting the eye, axons of ganglion cells leaving the eye, optic disk 2. To view nearby objects, tension on the eye lens must _____ relax or decrease _ ________. Also accepted: be reduced 3. Injecting cGMP into a rod of the retina will cause the rod to _____ depolarize ______. 4. According to Hubel and Wiesel’s experiments, how will orientation preference vary if you record from neurons in striate cortex along an electrode penetration perpendicular to the surface of the brain? The orientation tuning (or preference) of all the recorded neurons will be the same, Also accepted: Preference will not vary, It will not, similar

Version AM-KEY: Page 2 of 12 Name:……… KEY ………. ID:………………………………. 5. Achromatopsia is likely to be the result of damage to the ___ ventral pathway _____. Also accepted: “what” pathway, temporal pathway, cones, parvocellular pathway Not accepted: fovea (this would not cause a selective loss of color vision) 6. Opening potassium channels on the stereocilia of inner hair cells causes the inner hair cells to _____ depolarize ____. Also accepted: have an influx of potassium ions 7. To localize sound, the MSO (medial superior olive) requires the ____ volley theory ___ of sound frequency encoding to be in use by the auditory system. Also accepted: phase-locking NOT ACCEPTED: I did not accept “coincidence detection” or “coincident input” (or variations on this), “interaural timing differences”, “timing”, and “delay” because they do not describe how sound frequency is encoded.

Version AM-KEY: Page 3 of 12 Name:……… KEY ………. ID:………………………………. 8. Lesioning the LSO (lateral superior olive) on the right side of the brain will disrupt sound localization from which side(s) of the body? Both (you need both LSO’s to accurately localize sound from either side of the body) right side (In lecture I discussed why you need both LSOs to decode sound location – I would still say that to decode sound location you need both LSOs. The book states that each LSO encodes sound location from one side, the difference is very subtle - I will accept the right side as a correct answer) 9. Name one part of the brain that receives direct input from the retina _____ lateral geniculate nucleus ________. Also accepted:
