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

The part of the limbic system that plays important roles in the consolidation of information from short-term memory to long-term memory is the:

The main sensory receptive area for the sense of touch is

1. the precentral gyrus
2. the postcentral gyrus
3. Wernicke's area
4. The amygdala

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

The emotion of fear is processed by:
1. the frontal lobes
2. the angular gyrus
3. the thalamus
4. the limbic system

A malfunction of the corpora quadrigemina would affect:
1. vision and hearing
2. thermoregulation and osmoregulation
3. olfaction and taste
4. sleep and wakefulness

An injury to the cerebellum would most probably lead to:

The seat of the origin of the vagus nerve is:

1. red nucleus of the midbrain
2. epithalamus
3. pons
4. medulla oblongata

When a person enters a dark room, in the rods of his eyes:

1. cGMP levels are high.
2. cGMP levels are low.
3. G protein is degraded.
4. An influx of Ca²⁺ ions is prevented.

A proprioceptor can detect:

1. taste
2. odor
3. gravity
4. pain
