Chapter 10: PARENTAL BEHAVIOUR Flashcards
What is parturition ?
The act of giving birth
What is one important example of maternal behavior?
-Nest-building
What hormones play an important role in rodent nest-building behavior?
-prolactin and progesterone
How do pregnant female rats behave with foster pups that are given to them during pregnancy?
- They do not immediately care for them
- However they will do so as soon as their own pups are born.
What hormones influence female rodent’s responsiveness to her offspring ?
- ones that are present shortly before parturition
- progesterone, estradiol, prolactin
According to the findings of Neuman, what do lesions of the MPA (medial preoptic area) result in ?
- disrupts both nest building and pup care
- however, female sexual behavior was unaffected by these lesions
What do connections between AH and PAG play a role in?
defensive behavior and avoidance response
What role of MPA did Numan find?
- inhibit activity of AH
- allows for habituation to odour of pups
Medial amygdala in habituation to aversive odours?
-Lesions abolish the aversion of virgin females to pups
Medial amygdala in habituation to aversive odours?
-Lesions abolish the aversion of virgin females to pups
Medial preoptic area in habituation to aversive odours?
- activated by hormones and stimuli from pups
- inhibits the AH and PAG
Nucleus accumbens in maternal behavior?
- DA released during maternal behavior
- Injection of DA antagonist disrupts maternal behavior
Ventral pallidum in maternal behavior?
-inhibition of neural activity disrupts maternal behavior
Medial preoptic area in maternal behavior?
-Lesions disrupt maternal behavior
What does damage to connection between Medial Preoptic area and ventral tegmental area result in?
-disrupts maternal behavior
