To understand much of the chemistry To behind emotions, first information was gathered about the processes of brain’s functions involving… brain’s Neurons Neurotransmitters Synapse was understood, the connection between the brain’s “chemical imbalance” and emotions was researched. Once the basic physiology of the brain Once This Is Your Brain. This General Anatomy General

Cerebrum includes 4 lobes (arietal, Cerebrum frontal, temporal, occipital) frontal,
Frontal lobe is where it’s at. Frontal
