Question 1. In the hippocampus, neurons in the dentate gyrus sends their excitatory output mainly to:
Question 2. Compared to passive membranes in the dendrites, the amplitude of back-propagating action potentials is larger or smaller when the dendrites contain voltage-gated Na channels?
Question 3. Why does the width of the action potential affect synaptic release?
Question 4. For feedback inhibition, high levels of activity in a pyramidal neuron would lead to:
Question 5. SOM+ GABAergic interneurons synapse on distal dendrites. PV+ GABAergic interneurons synapse on the soma. What could you do to SOM+ interneurons to make their inhibitory effect on the pyramidal neuron comparable to that for PV+ interneurons?
