Mammalian Brain

Next to evolve from the reptilian brain was the mammalian brain. An enormous change took place as mammals evolved from reptiles, the mammalian brain containing organs:

For the automatic control of body functions such as digestion, the fluid balance, body temperature and blood pressure (autonomic nervous system, hypothalamus).

For filing new experiences as they happen and so creating a store of experience-based memories (hippocampus).

For experience-based recognition of danger and for responding to this according to past experience. And for some conscious feelings about events (amygdala).

To this extent the mammal is more consciously aware of itself in relation to the environment. Millions of neural pathways connect the hippocampal and amygdala structures to the reptilian brain and behaviour is less rigidly controlled by instincts. It seems that feelings such as attachment, anger and fear have emerged with associated behavioural response patterns of care, fight or flight. {4}
