2. Describe the different causes and mechanisms of osmotic thirst. ANS: Osmotic thirst is caused by an increased concentration of solutes in the extracellular fluid, either by increased salt intake, or water loss. Osmotic thirst is detected by neurons in the OVLT that cause increased release of vasopressin (which decreases urine output and raises blood pressure) and increased activity in the LPO to initiate drinking, preferably of pure water.

3. Describe the different causes and mechanisms of hypovolemic thirst. ANS: Hypovolemic thirst is caused by low blood volume. The kidneys release renin, which initiates the process of converting angiotensin into angiotensin II. Angiotensin II stimulates the OVLT and SFO to induce drinking. Aldosterone released by the adrenal glands and angiotensin II alter taste preference for sodium. The end result is restoring both water and salt. PTS: 1 Hunger

2. Briefly describe the role of the left and right hemispheres contribution to emotions according to Jeffrey Gray. ANS: Activity of the left hemisphere, especially its frontal and temporal lobes, relates to what is called the Behavioral Activation System (BAS), marked by low to moderate autonomic arousal, and a tendency to approach, which could characterize either happiness or anger. Increased activity of the frontal and temporal lobes of the right hemisphere is associated with the Behavioral Inhibition System (BIS), which increases attention and arousal, inhibits action, and stimulates emotions such as fear and disgust.

4. Briefly describe how benzodiazepines work in the brain. ANS: Benzodiazepines bind to the GABAA receptor, which includes a site that binds GABA as well as sites that modify the sensitivity of the GABA site. When a benzodiazepine molecule attaches, it neither opens nor closes the chloride channel but twists the receptor so that the GABA binds more easily. Benzodiazepines thus facilitate the effects of GABA. Benzodiazepines exert their anti-anxiety effects in the amygdala, hypothalamus, midbrain, and several other areas.

5. Briefly describe the role of the HPA axis and the autonomic nervous system (ANS) in the stress response. ANS: The ANS reacts very quickly to prepare the body for "fight or flight" by increasing heart rate, blood pressure, decreasing stomach secretions, etc. The HPA axis reacts more slowly, resulting in the release of cortisol from the adrenal gland. Cortisol helps the body mobilize energy. However, prolonged HPA activation can lead to immune suppression and deterioration of the hippocampus, resulting in impaired memory. PTS: 1 Cortex Axis
