Exam 2 Flashcards
**What is the brain region that is responsible for coordinating male sex behavior?
Medial Preoptic Area (mPOA)
Courtship behavior falls into the phase of sexual behavior.
Appetitive phase
This dopamine pathway is involved in “crystallizing” sex behavior.
mesolimbic pathway (reward pathway or VTA - NAc)
This treatment eliminates sex behavior in some, but not all, males.
Castration
Experienced rats will perform this action hundreds of times to access a receptive female.
lever pressing
Approaching and then darting away from a male is this type of sex behavior.
Proceptive behavior
Females that have a recurring physiological change in reproductive change in reproductive hormones but do not shed uterine lining have this type of cycle.
Estrus Cycle
GnRH from the hypothalamus induces the release of these hormones from the pituitary during the estrus cycle.
luteinizing hormone (LH) and Follicle stimulating hormone (FSH)
The hormone associated with maximal proceptivity, attractivity, and receptivity in female monkeys.
estrogen
This neural module is responsible for the integration of posture information during lordosis.
Lower brain stem
What type of young are born immature or helpless?
Altricial young
This hormone is made by both the corpus lutetium and placenta and is necessary for maternal behavior.
progesterone
This hormone stimulates nest building in some species.
prolactin
Changes to estrogen receptors in the brain region are associated with maternal behavior.
Medial Preoptic Area (mPOA)
This region is involved in processing tactile/touch cues that facilitate maternal behavior.
Parietal cortex
Females that have many breeding cycles that are limited to specific times of year have this type of estrus cycle.
Polyestrus
The effect where the introduction of a new female can eliminate the male post-ejaculatory refractory period.
The Coolidge Effect
A female that has had more than one pregnancy is known as…
Multigravida
This stimulus elicits anxiety/avoidance in nulliparous female rats.
Pup smell
Increase in this hormone is associated with paternal behavior.
prolactin
Hormones and this are required to produce optimal male reproductive behavior.
Prior Reproductive Experience
This is the main hormone that is increasing during the follicular phase of the ovarian cycle.
Estrogen
This term refers to the gradual increase in maternal behavior of virgin rodents after many exposures to pups.
concaveation
This term refers to one effect of environment on hormones, where group housed female rodents will stop displaying estrus cycles.
Lee- Boot Effect
This brain region is altered in rat moms by estradiol to decrease the central aversion stimulus of novel pups.
Medial amygdala
What did Charles Edouard Brown-Sequard do in 1889?
- He injected himself with aqueous solution of homogenized dog & guinea pig testes
-> prompted medical interest in steroid hormones
Male Appetitive Phase
- courtship, searching, advertising (show readiness to mate and genetic endowments), fighting for territory
- sex drive = motivation
Mounting (definition)
male assumes a copulatory position
Intromission (definition)
penis enters vagina
Ejaculation (definition)
forceful expulsion of semen from male’s body
Post-ejaculatory Interval (PEI) (definition)
time between ejaculation and onset of next copulatory series (aka refractory period)
Androgens and Sex Behavior
- Androgens affect the likelihood of male sex behaviors occurring by reducing the threshold for the behavior (in a specific context)
- only one part of what will result in successful
Lidocaine
