dopamine hypothesis : the theory that schizophrenia results from excessive activity of the neurotransmitter dopamine dopamine hypothesis- nigrostriatal pathway : The nigrostriatal dopamine pathway that projects from the substantia nigra to the basal ganglia or striatum, is part of the extrapyramidal nervous system and controls motor function and movement. Mesolimbic dopamine hypothesis: Hyperactivity of dopamine neurons in the mesolimbic dopamine pathway cause what symptoms of schizo...

Dopamine belongs to the family of catecholamines. It is a neurotransmitter. • Hormones, Epinephrine and Norepinephrine (other catecholamines) are derived from Dopamine • Dopamine plays a significant role in learning, goal-directed behavior, regulation of hormones, motor control. DOPAMINE SYNTHESIS Phenylalanine (amino acid from diet) -> phenyalanine hydroxylase -> Tyrosine -> Tyrosine hydroxylase -> DOPA -> Dopa decarboxylase -> Dopamine KEY POINT: Dopamine is synthe...

what ages are most affected by heroin overdose? - Answer- young adults (18-25 y/o) and middle adults what is the correlation between heroin and other drug use? - Answer- - 9/10 people who use heroin have used at least 1 other drug - 45% of people on heroin were addicted to prescription opioids what trends have occurred by reducing opioid prescriptions in last 5 years? - Answer- heroin use has gone up, so people are just switching to heroin and so people are ODing on heroin. how long do...

Neurobiological Basis: Neural Networks - answer-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 - answer-Dopamine is responsible for regulating the brain's motivation, pleasure, and reward ...

Mesocortical pathway - executive function: attention, focus, depression Nigrostriatal pathway - from substantia nigra (brainstem) to striatum (muscles): Parkinson's Mesolimbic pathway - projects to nucleus accumbens (part of limbic system).
