I will praise Thee; for I am fearfully and wonderfully made:
marvellous are Thy works;
Psalm 139:14
The basal ganglia, specifically the striatum tail, located in the deepregion of the brain, plays a critical role in associating objects with their value through long-term experience.
The caudate nucleus responded strongly to familiar faces but weakly to unfamiliar ones. Moreover, the same neurons responded similarly to the varying values of objects. Considering that these neurons are also involved in rapid identification of valuable objects, they may be important in enabling children and pets to quickly identify familiar individuals.
These findings elucidate the mechanisms through which the brain forms and maintains social relationships."
