caudate

This is infused deep into the brain using real-time MRI scanning to guide a microcatheter to two brain regions - the caudate nucleus and the putamen.

Researchers found that the brain region associated with positive rewards, the caudate nucleus, was most activated by the scent of their familiar human; the study was published in the journal Behavioural Processes in 2014.

One study used MRI imaging to study activity in the caudate nucleus, a brain area associated with the expectation of a reward.

Some studies suggest that people with autism and people with OCD both have an unusually large caudate nucleus, a structure within the striatum.

These included the caudate nucleus, part of the reward system, and an ancient brain area called the ventral tegmental area, or VTA.
