| Research Abstract |
In order to investigate our hierarchical decision process that includes from choosing an abstract goal to a concrete movement, we investigate striatal neural activity during monkeys performing a decision task of selecting cognitive goal-stimulus that temporally dissociated from selecting actual movement. By the neural representation recorded from anterior striatum, we found the pre-decisive possible offered-target information and also post-decisive chosen-target information in the striatum. These result of the study suggest that the multiple cortico-basal ganglia circuit might involves multiple abstract-levels of decision making, especially anterior-medial part of the caudate nucleus might be involved in abstract target selection process.
