→ influence whether genes associated with substance use disorder are activated


Neurological Basis: Neuroanatomy in SUD


→ Brain circuits that mediate reward, impulse control, decision making, learning, and
emotions play a role in substance use disorder.


Mesolimbic Dopamine pathway in SUD

→ has been identified as the key pathway that mediates reward.
→
→ Connects the ventral tegmental area of the midbrain to the ventral striatum of the
basal ganglia.
→
→ The pathway begins in the ventral tegmental area (VTA) and connects to the ventral
striatum/nucleus


Neurobiological Basis: Neural Networks

→ Mesolimbic pathway is most associated with reward. Drugs and alcohol act directly on
brain receptors leading to a release of dopamine.
→
→ As substance use increases, brain circuits adapt by reducing sensitivity to dopamine,
leading to tolerance and the need to increase use of a substance to achieve the same
high.


Neurological Basis: Neural Signaling

→ Dopamine is responsible for regulating the brain's motivation, pleasure, and reward
center.
→
→ Dopamine is release in response to natural pleasurable activities or situations such as
achieving an accomplishment, enjoying a good meal. or participating in an athletic
activity. Addictive drugs cause a surge of dopamine in the ventral striatum or nucleus
accumbens.
→ Repeated use can lead to changes in brain circuitry leading to craving, addiction,
dependence, withdrawal.
