HMB200H1 Study Guide - Final Guide: Ventromedial Nucleus Of The Hypothalamus, Bulbospongiosus Muscle, Vomeronasal Organ
Document Summary
Activating amygdala can elicit multiple effects: important effect: can trigger hypothalamus. Activating hypothalamus leads to goal-driven/motivated behaviours. Drive provides force to act purposefully towards a goal: adaptive, promotes survival. Activated by triggers: internal triggers (hunger, curiosity, external triggers (sights of food) Operant conditioning: triggers can be learned operant conditioning. Operant & classical conditioning often work in tandem. Physical development: primary sexual characteristics: genetics, sry gene leads to differentiated gonads a. i. Activational effects: hormones, steroid hormones testosterone, estrogens, affects gene activation major structural effects. Developmental processes pause after birth, until puberty: hormones & genes. Sexually dimorphic behaviours: differen ces in sexual behavio urs, b/w. 2 sexes: caused by drive stimuli, differen ces triggere d by. Dimorphic brain development different behaviours & triggers. Sexual behaviour occurs usually in estrus: estrogen surge 2 days prior. Activates receptive behaviour rone surge 6 hours after. Receptive behaviours facilitated by stimulation of mounting males.
