The dopamine pathways in the brain Dopamine is transmitted via three major pathways. The first extends from the substantia nigra to the caudate nucleus-putamen (neostriatum) and is concerned with sensory stimuli and movement. The second pathway projects from the ventral tegmentum to the mesolimbic forebrain and is thought to be associated with cognitive, reward and emotional behaviour. The third pathway, known as the tubero-infundibular system, is concerned with neuro…

Basal Ganglia: -The caudate and putamen also receive input from the substantia nigra pars compacta -This area makes dopamine

Basal Ganglia: Caudate, putamen, and the globus pallidus -The substantia nigra and the subthalamic nucleus (in the ventral thalamus) are also associated with these nuclei

Panda sign: The panda sign in neuroimaging refers to the appearance of the midbrain, when the red nucleus and substantia nigra are surrounded by high T2 signal.(Click link for addl. images) It is classically seen in Wilson disease, although whenever the white matter is diffusely abnormal in the region a similar appearance will be perceived.
