MALE BRAIN Temporal Parietal Junction The place where the temporal lobe (responsible for auditory functioning, memory and speech cognition) and the parietal lobe (responsible for sensory information) meet. It is more active in males, MRI’s have shown. TPJ works to cognitively process emotion, which strengthens their ability to cognitively and analytically find a solution to emotional problems as opposed to empathize – which women are more likely to do, says Louann Brizendine (author of The…

Dopaminergic neurons and their projections. Axons of dopaminergic neurons located in the substantia nigra pars compacta ascend rostrally as the nigrostriatal pathway and provide dopaminergic innervation to neurons located in the caudate nucleus and putamen (striatum). Axons of another group of dopaminergic neurons that are located in the ventral tegmental area ascend in the median forebrain bundle to provide dopaminergic innervation to the frontal and cingulate cortices.

2-Minute Neuroscience: Suprachiasmatic Nucleus

Ventral Tegmental Area (VTA) is the area that synthesizes dopamine, which then sends to nucleus accumbens. Nucelus accumbens is the pleasure center, and it is stimulated by the neurotransmitter dopamine from VTA. VTA also sends dopamine to prefrontal cortex which regulates and controls these impulses. The locus coeruleus is the area packed with norepinephrine; and when stimulated by a lack of the addictive substance, will drives the person to do anything necessary to obtain a fix.
