  8. 8. IS LOVE ADDICTIVE?Love also releases a biochemical rush of dopamine, norepinephrineand phenyl ethylamine. This is similar to the chemicals released duringthe use of certain drugs. Just like any other chemicals, you can buildup a tolerance meaning you need more of these chemicals to get thesame rush/feeling.Some neuroscientists suggest that people who jump from relationshipto relationship are addicted to these effects of early love.

PA R T S O F T H E B R A I N T H A T A R E AFFECTED BY THE EMOTION OF LOVE AMYGDALA: Responsible for multiple emotional responses such as love, fear, angerand sexual desire. HIPPOCAMPUS: Part of the limbic system which sends information to theamygdala. PREFRONTAL CORTEX: Used in decision making in response to emotions. Alsoregulates anxiety. HYPOTHALAMUS: Also part of the limbic system which sends information to theamygdala. Regulates emotions such as sexual desire , pleasure & aggression. CINGULATE GYRUS: Acts as a pathway between the thalamus and hippocampus.It plays a role in remembering emotional events. VENTRAL TEGMENTAL AREA: Dopamine pathways are located in this area.
