WebWhat are the two dopamine pathways? 1.1 Mesocorticolimbic Circuits and rsFC The mesolimbic and mesocortical pathways, two of the brain’s major dopaminergic pathways, have been implicated as key circuits that are disrupted in addictive behaviors (Blum et al., 2012). What is the Mesocortical system responsible for? WebWhat is Mesocortical pathway? one of the main dopamine pathways of the brain, the mesocortical pathway runs from the ventral tegmental area to the cerebral cortex. It forms extensive connections with the frontal lobes, and is thought to be important to a wide range of functions, such as motivation, emotion, and executive functions.

The mesolimbic pathway, sometimes referred to as the reward pathway, is a dopaminergic pathway in the brain. The pathway connects the ventral tegmental area in the midbrain to the ventral striatum of the basal ganglia in the forebrain. The ventral striatum includes the nucleus accumbens and the olfactory tubercle.
