Action Selection and Action Value in Frontal-Striatal Circuits
The role that frontal-striatal circuits play in normal behavior remains unclear. Two of the leading hypotheses suggest that these circuits are important for action selection or reinforcement learning. To examine these hypotheses, we carried out an experiment in which monkeys had to select actions in two different task conditions. In the first (random) condition, actions were selected on the bas...
متن کاملStriatal action - value neurons reconsidered
8 It is generally believed that during economic decisions, striatal neurons represent the values 9 associated with different actions. This hypothesis is based on a large number of 10 electrophysiological studies, in which the neural activity of striatal neurons was measured 11 while the subject was learning to prefer the more rewarding action. Here we present an 12 alternative interpretation of...
متن کاملDysfunctional action monitoring hyperactivates frontal-striatal circuits in obsessive-compulsive disorder: an event-related fMRI study.
Converging evidence suggests that hyperactivity in frontal-striatal circuits and in action-monitoring processes characterizes obsessive-compulsive disorder (OCD). It remains unclear, however, just how these abnormalities in brain function translate into the cognitive, affective, and behavioral manifestations of OCD. One possibility is that exaggerated or false error signals generated by the ant...
متن کاملAction mirroring and action understanding in children
The past decade has experienced an increasing interest in action underestanding and children’s mirroring of others’ behavior. Behavioral investigations have focused on the development and significance of mimicry, goal prediction and imitation. Others have focused on the neural basis of action mirroring, identifying particular electrophysiological markers or related brain regions. A vivid debate...
متن کاملIntention, Action Planning, and Decision Making in Parietal-Frontal Circuits
The posterior parietal cortex and frontal cortical areas to which it connects are responsible for sensorimotor transformations. This review covers new research on four components of this transformation process: planning, decision making, forward state estimation, and relative-coordinate representations. These sensorimotor functions can be harnessed for neural prosthetic operations by decoding i...
