Hypothalamus controls the emotions like fear, anger, excitement, pleasure, feeding behaviour, sexual arousal and bodily responses to the emotions. Hypothalamus regulate the levels of gonadal hormones and thus, the sexual behaviour.
The amygdala plays an important function in processing emotions, and is connected to dual functions such as fear and pleasure responses such as sex in humans and other animals.
