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.

Huntingtons's disease The caudate nucleus heads are markedly atrophic resulting in enlargement of the frontal horns and increased inter-caudate distance (22mm) and increased inner table to intercaudate caudate ratio (0.23 (normal 0.09 - 0.12)). Putamen are also markedly decreased in size with increased T2 signal.
Why it's time to investigate the overlap between autism and ADHD
Structures of the brain that were investigated in the research published in the journal Plos One. The caudate nucleus, which was found to be able to predict levels of autistic traits in ADHD participants, is shown in red.
