1) Action potentials are electrical signals that are conducted down the axon of a neuron.
2) When someone is emotionally aroused, the hippocampus plays a modulatory role in
strengthening the consolidation of amygdala-based memory.
3) Single axons of the corticospinal tract can extend for more than one meter.

hemisphere by presenting it visually in the right visual field.
5) When performing a single-cell recording, researchers typically carefully insert a thin
electrode through the cell membrane into the interior of a neuron.
6) People with frontal lobe lesions are often impaired in organizing and segregating
events in memory.

8) Dendrites, which are large treelike processes extending from a neuron, are said to be
presynaptic.
9) Before a movement is initiated, the population vector in the motor cortex has already
shifted in the direction of the planned movement.
10) The term commissure refers to the white matter tracts that connect the brain and
spinal cord.
11) The amplitude of an action potential is directly proportional to the size of the initial
depolarization that produced it.
12) Patients with associative agnosia can typically describe the functions of objects if
they are given the names of the objects verbally.
13) Category-specific deficits may be an emergent property of the fact that different
kinds of information are needed to recognize living and nonliving objects.
14) If the sum of the excitatory postsynaptic potentials (EPSPs) causes a postsynaptic
neuron to reach its threshold, then the postsynaptic neuron will generate an action
potential.

primarily involves late selection.
d. auditory attention primarily involves early selection, whereas visual attention
primarily involves late selection.

b. frontal ; parietal
c.parietal ; occipital
d. occipital ; temporal
