Sexual interactions with a new male induce all of the following in female prairi

Question

Sexual interactions with a new male induce all of the following in female prairie voles EXCEPT... Ovulation Formation of a preference for the male Increased release of oxytocin in the brain Increased expression of oxytocin receptors in the brain Increased release of dopamine in the brain In praine voles, brain regions that mediate effects of copulation on partner preference formation are most closely linked to the... Endocrine system Reward pathway Olfactory system Sexually dimorphic nucleus of the hypothalamus Lordosis circuitry Compared to promiscuous voles, monogamous voles have high levels of ... Testosterone in the blood Vasopressin in the lateral septum Vasopressin receptors in the ventral pallidum Oxytocin in the prefrontal cortex Oxytocin receptors in the supraoptic nucleus In humans, treatment with oxytocin has been shown to have all of the following effects EXCEPT... Inducing formation of a pair bond in females Increasing trust towards other people Improving social cognition in autistic individuals Decreasing neural responses to threatening-looking faces Enhancing the ability to infer other people's emotional states Aggression in rodents can be affected by exposure to steroid hormones during all of the following stages EXCEPT... Prenatal development Early postnatal development Puberty Adulthood None of the above (i.e., aggression can be affected by steroid hormone exposure during all of these stages).

Explanation / Answer

1. Option E is correct. Except option E other 4 options are followed during sex interaction between male and female pairie vole. vasopression found in male and oxytoxin in female.

2. Option B is correct

Because Oxytoxin receptors of female prairie vole are localized as reward system, they have more receptors in comparison to other species. This part produces feeling and pleasure of reward

3. Option C is correct

Monogamous have high number of vasopression, which are located in ventral pallidum as per research article published in few journals.

4. Option E is correct. In humans the oxytoxin used to improve social behavior. It acts as chemical messenger who affect the person behavior in term of sexual arousal, trust, recognition, and anxiety. So It will increase the person intellectual behavior. But it will not stimulate the thought of interfering in other people life.

5. Option A is correct Parental stage is that at which egg is form zygote then embryo. In this stage the brain is not developed as much to respond as aggression.
