A diffuse network of nerve pathways in the brainstem connecting the spinal cord, cerebrum, and cerebellum, and mediating the overall level of consciousness is the:

1. Hippocampus
2. Hypothalamus
3. Reticular activating system
4. Limbic system

Motor aphasia may result due to the lesion of:

1. Broca's area
2. Wernicke's area
3. the cingulate gyrus
4. the angular gyrus

Assertion: A person with damage to Broca’s speech area in the left hemisphere may not be able to speak but may retain the ability to sing.
Reason: The left hemisphere is the dominant hemisphere for language in majority of the human beings.

1. Both assertion and reason are true and the reason is the correct explanation of the assertion.
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false.

The waves most likely to appear on an EEG due to active, busy or anxious thinking and active concentration would be:
1. alpha wave
2. beta wave
3. theta wave
4. delta wave

Located in the lower portion of the frontal lobe, the Broca's area is primarily concerned with:

1. visual reflexes
2. motor speech
3. neural hearing
4. sensory impulses

The precentral gyrus in the parietal lobe is the primary:
1. sensory area
2. visual area
3. auditory area
4. motor area

Odors can alter our moods:

1. Because sensory input from olfaction is routed through the limbic system.

2. Because odors act as neurotransmitters and alter brain chemistry.

3. Because odors are satisfying to our sense of hunger.

4. Odors do not alter mood.
