Answer 2

6

Question 3

What are the 6 nuclei involved in the SBN

Answer 3

Lateral septum
Medial extended amygdala/ bed nucleus of the stria terminalis
preoptic area
anterior hypothalamus
ventromedial hypothalamus
periaqueductal gray/ central gray/ tegmentum

Question 4

What does the Lateral Septum (LS) do in the SBN?

Answer 4

• emotional processing
• stress response
• organise mammalian kinship behaviour
• regulates affects (i.e: reward, feeding, anxiety, fear, socialibility, memory etc)

Question 5

In the SBN, what does the preoptic area (POA) do?

Answer 5

• contains neurons that are sensitive to subtle change in hypothalamus/ core temperature
• receives somatosensory input from skin and thermoreceptors in spin
• regulates social behaviour
• regulates social reward
• mediates sexual behaviour
• mediates aggression
• mediates parental care

Question 6

In the SBN, what does the anterior hypothalamus (AH) do?

Answer 6

integrates thermal information from body thermoreceptors

Question 7

In the SBN, what does the ventromedial hypothalamus (VMH) do?

Answer 7

• regulates female sexual behaviour
• regulates feeding
• energy balance
• cardiovascular function

Question 8

In the SBN, what is the periaqueductal gray/ central gray/ tegmentum involved in

Answer 8

• pain & analgesia (pain-relief)

Question 9

What area of the SBN is most involved in the pain inhibitory system?

Answer 9

Periaqueductal gray/ central gray area
