Striatal 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 کاملAction 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 کاملActivity of striatal neurons reflects social action and own reward.
Social interactions provide agents with the opportunity to earn higher benefits than when acting alone and contribute to evolutionary stable strategies. A basic requirement for engaging in beneficial social interactions is to recognize the actor whose movement results in reward. Despite the recent interest in the neural basis of social interactions, the neurophysiological mechanisms identifying...
متن کاملVentral striatal neurons encode the value of the chosen action in rats deciding between differently delayed or sized rewards.
The ventral striatum (VS) is thought to serve as a gateway whereby associative information from the amygdala and prefrontal regions can influence motor output to guide behavior. If VS mediates this "limbic-motor" interface, then one might expect neural correlates in VS to reflect this information. Specifically, neural activity should reflect the integration of motivational value with subsequent...
متن کاملMirror neurons encode the subjective value of an observed action.
Objects grasped by an agent have a value not only for the acting agent, but also for an individual observing the grasping act. The value that the observer attributes to the object that is grasped can be pivotal for selecting a possible behavioral response. Mirror neurons in area F5 of the monkey premotor cortex have been suggested to play a crucial role in the understanding of action goals. How...
