“Addicted” Brain Prefrontal cortex (PFC) Part of the frontal lobe that is involved in many cognitive functions, including memory, language and decision making. The VTA-NA ‘common reward’ pathway Nucleus Accumbens – (NA) A small region in the forebrain with ancient evolutionary origins, which helps regulate survival drives like food and thirst. Affected by drugs including cocaine, amphetamine, cannabinoids (e.g cannabis) and opioids (e.g. heroin). Ventral Tegmental Area– (VTA) Found in the midbrain, this area produces dopamine and forms part of one of four major dopamine pathways in the brain. Affected by drugs including; nicotine, alcohol and opioids (e.g. heroin). Dopamine movement Amygdala Striatum MDP Pathway
