Dopamine exerts different effects in different regions and pathways throughout the brain. In the <strong>mesolimbic pathway</strong>, dopamine is believed to be involved in motivation and addiction due to the feelings of reward and pleasure associated with dopamine release here. In the <strong>mesocortical pathway</strong>, dopamine is linked to emotional and motivational activities. In the <strong>nigrostriatal pathway</strong> dopamine is responsible for regulating and initiating motor activity. In the <strong>tuberoinfundibular pathway</strong>, dopamine regulates the release of hormones from the pituitary gland.</li>

<p>No, unlike norepinephrine and serotonin, dopamine's pathway is limited.actually it affects two part of cognition, reward and motor functions.
As part of the reward pathway, dopamine is manufactured in nerve cell bodies located within the ventral tegmental area (VTA) and is released in the nucleus accumbens and the prefrontal cortex. The motor functions of dopamine are linked to a separate pathway, with cell bodies in the substantia nigra that manufacture and release dopamine into the striatum.</p>

<p>Quoting my thesis:</p>

<p>CNS Dopamine/DA projections primarily emerge from two subcortical basal ganglia nuclei in the brain stem, travelling along three major pathways (Purves et al., 2004).</p>
<p>The nigrostriatal pathway, connecting the substantia nigra and the striatum, is mainly implicated in higher motor control. The mesolimbic pathway contains DA projections from the Ventral Tegmental Area/VTA and the pars compacta of the Substantia Nigra (SNc) to limbic systems including hip- pocampus, amgydala and thalamus, and is critical in learning and memory in a mechanism that is well-investigated (Lisman &amp; Grace, 2005). The mesocortical pathway connects the VTA and SNc to the cortex. In contrast to the extensive noradrenergic innervation of the cortex, DA therefore reaches only selected areas (Foote &amp; Morrison, 1987). DA density is extensive in prefrontal and anterior cingulate areas, and falls off rapidly across an rostro-caudal gradient. The temporal lobe is only weakly innvervated (including the enthorinal cortex), and little to no innervation reaches parietal and especially occipital lobes, though DA fibers in monkey area 7 have been reported (Foote &amp; Morrison, 1987).</p>

<p>Of course, this is only the <em>direct</em> effect of DA. In principle, all of the brain is strongly affected by the effects of DA, because frontal cortices, who are strongly influenced by DA, in turn strongly influence the rest of the bain.</p>

Quoting my thesis:

> The nigrostriatal pathway, connecting the substantia nigra and the striatum, is mainly implicated in higher motor control. The mesolimbic pathway contains DA projections from the Ventral Tegmental Area/VTA and the pars compacta of the Substantia Nigra (SNc) to limbic systems including hip- pocampus, amgydala and thalamus, and is critical in learning and memory in a mechanism that is well-investigated (Lisman & Grace, 2005). The mesocortical pathway connects the VTA and SNc to the cortex.

The temporal lobe is only weakly innvervated (including the enthorinal cortex), and little to no innervation reaches parietal and especially occipital lobes, though DA fibers in monkey area 7 have been reported (Foote & Morrison, 1987).

So basically, subcortical innervation is rich, but cortical innervation is focused on frontal areas. DA is often depicted as having *zero* cortical presence outside of frontal areas, but this is false; while DA innervation density falls off sharply outside of the frontal lobes, at least in humans and other apes, there is some DA reaching at least as far back as the temporal lobes.

Of course, this is only the *direct* effect of DA. In principle, all of the brain is strongly affected by the effects of DA, because frontal cortices, who are strongly influenced by DA, in turn strongly influence the rest of the bain.
