This page covers biological details of component group Subthalamus Area. Component group is part of aHuman target integrated biological model.

• Top-down path to center: Forebrain Diencephalon -> Subthalamus Area (FEC.FD.STA) (see Mind Maps)
• Function: Perform action selection
• Notes to function: Dysfunction increases impulsivity in case of two equally rewarded stimuli
