Biological Explanations Schiz
-Snyder said during a synapse to much dopamine is released leading to schiz.
-sufferers show high levels of D-2 receptors causing more dopamine.
-theory developed when it was found antipsychotic drugs used to treat schiz inhibited dopamine activity.
-dopamine releasing drug (L-dopa), LSD creates schiz behaviour
-genetic factors may create faulty dopamine systems
-Davis.. high levels in mesolimbic dopa system = positive symptoms high levels in mesocortical dopa system = negative symptoms
-reduced function of NMDA glutamate receptor in schiz. Dopa receptors inhibit release of glutamate... causing schiz.
