9B. Monocular deprivation (keeping one eye closed). Axons from LGN layers responding to the closed eye lose almost all territory in the cortex, axons from the open eye layers take over more cortex than usual. 9C. Injection of tetrodotoxin to stop all neuronal activity in the pathways from both eyes. Axons from both eyes remain overlapping in the immature state. 10. Name two factors that determine whether the current flowing through an open channel will be an inward current or an outward current. Factor 1. Concentration gradient(s) of the ion(s) flowing through the channel. Factor 2. Membrane potential. 11. You pluck the dense feathers from above the left ear of an owl. You then do an experiment and ask the owl to orient to sounds from different locations in space. Note : plucking the dense feathers will effect the intensity at which a sound will arrive at the ear but

Unformatted text preview: NOT THE TIME at which the sound arrives at the ear. 11a. When the sound is presented at 60 degrees to the left and 30 degrees below, the owl will orient to the sound as if the sound were __________ than it really is at. Circle One: Higher Lower At same elevation 11b. When the sound is presented at 60 degrees to the left and 30 degrees below, the owl will orient to the sound as if the sound were __________ than it really is at. Circle One: More Left More Right At same azimuth 11c. When the sound is presented at 30 degrees to the left and 30 degrees above, the owl will orient to the sound as if the sound were __________ than it really is at. Circle One: Higher Lower At same elevation 11d.
