1. If a drug increases the rate of reuptake this will: diminish the effects of the neurotransmitter.
2. Due to a minor stroke, Kerry has a tiny lesion in the left primary visual cortex, the most likely
result will be: a small "hole" in a particular region of the right visual field.
3. Neurons A, B, C, D, and E synapse with Neuron F. Neurons A, C, and E are inhibitory, and
neurons B and D are excitatory. If action potentials occur in neurons B and D but not in neurons
A, C, and E, what is most likely to happen to Neuron F?
“It will fire because Neurons B and D will release transmitter substances that will excite
its postsynaptic membrane, generating postsynaptic excitatory potentials that add in the cell
body of Neuron F.”
4. A structure in the limbic system that plays an important role in the formation of memories is
5. In the primary motor cortex, the amount of cortical space devoted to a given body part depends

7. Dendrites on neurons do COLLECT EXCITATORY AND INHIBITORY POTENTIALS they do not
TRANSMIT ACION POTENTIALS
8. Which of the following is NOT TRUE:
i. White matter is white because of the fatty myelin that sheaths the axons.
ii. There are two major types of cells in cortex: neurons and glia.
iii. Neuron cell bodies are found equally in grey matter and white matter.
