Neural Basis of Gender
-
-
Gender and depression
Girls mainly experience body dissatisfaction, guilt, a harder time concentrating.
Boys experience more lack of joy, fatigue, and depressed mood.
Women are more likely to report weight gain, gastrointestinal issues, and sleeping a lot.

Parental Behavior
Behavior
95% of mammals are polygynous or promiscuous which is when after mating, males leave and females raise young alone, which is called uniparental Care.
-
-
Alloparental Behavior: Occurs when older siblings stay with the family and help care for new infants.

Circuits
Maternal Motivation and Behavior Activation: Pregnancy hormones and oxytocin suppress avoidance/rejection circuits and activate maternal behavior circuits.
(MPOA): located in the hypothalamus, is crucial for maternal motivation in mammals
Avoidance-Rejection Circuit: In females not primed with pregnancy hormones, infant stimuli activate a defensive circuit, promoting avoidance/rejection
-
MPOA neurons project to the VTA, which is part of the brain's reward system
Neural circuits involving the MPOA, dopamine pathways, and inhibitory/excitatory mechanisms regulate maternal motivation and behavior in mammals
