dopamine hypothesis - Answer-the theory that schizophrenia results from excessive activity of the
neurotransmitter dopamine
dopamine hypothesis- nigrostriatal pathway - Answer-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 schizophrenia - Answer-symptoms of psychosis such as delusions and
hallucinations. This pathway is also involved in pleasure, reward, and reinforcing behavior, and many
drugs of abuse interact here.
What conditions other than schizophrenia may cause positive symptoms? - Answer-Depression, mania,
dementia, drug-induced psychosis
Hyperactivity of the _______________________________ pathway may also play a role in the hostility
and aggression found with schizophrenia. - Answer-mesolimbic dopamine pathway
If there is too much dopamine in the basal ganglia causes what type of movements? - Answer-chorea,
dyskinesia and tics
Deficiency iof dopamine in the basal ganglia can also causes what types of movement? - Answer-
akathisia and dystonia.
