(3 points) On the axes below, draw a curve representing the responses of a cell that has equal numbers of synapses from the two ears. LABEL YOUR CURVE “Cell #1”. 1b. (3 points) On the same axes draw a curve showing the response of a cell that gets more synapses from the right ear than from the left ear. LABEL THIS CURVE “Cell #2”. 1c. (2 points) Which (if any) of these two cells will fire action potentials in response to a sound above the owl? Cell #1 and cell #2 1d. (2 points) Which (if any) of these two cells will fire action potentials in response to a sound below the owl? Cell #2 1e. (2 points) Which (if any) of these two cells will fire action potentials in response to a sound directly in front of the owl? Cell #2 1f. (3 points) You now put an earplug into the owl’s right ear. This ear plug decreases the loudness of sound in the right ear and also increases the delay to the right ear. On the axes above, draw a curve showing the response of Cell # 1 while the owl has the ear plug in. LABEL THIS CURVE “Cell #1 with ear plug”.
