Final answer:

The antipsychotic effects of antipsychotic medications are associated with the Mesolimbic-mesocortical pathway, which is targeted by these medications to block dopamine receptors and diminish psychosis symptoms.

Step-by-step explanation:

The antipsychotic effects of antipsychotic medications are primarily associated with the Mesolimbic-mesocortical pathway, which is one of the dopaminergic pathways in the brain. This pathway, also known as the mesocorticolimbic pathway, arises predominantly from the dorsal sheet of the substantia nigra compacta (SNc) and the ventral tegmental area (VTA) projecting to limbic regions such as the nucleus accumbens and the amygdala. The antipsychotic drugs mainly work by blocking dopamine receptors, particularly the D2 receptors, in these regions, which is believed to diminish the symptoms of psychosis. It's significant to note that while the antipsychotic effects are intended, these medications can also affect other dopaminergic pathways leading to side effects such as movement disorders.
