Responses of Tonically Active Neurons in the Monkey Striatum Discriminate between Motivationally Opposing Stimuli
The striatum is involved in the control of appetitively motivated behavior. We found previously that tonically active neurons (TANs) in the monkey striatum show discriminative responses to differentExpand

Tonically active neurons in the monkey striatum do not preferentially respond to appetitive stimuli
Abstract The tonically active neurons in the monkey striatum respond to stimuli presented during the performance of appetitively motivated behavior. To test whether these neurons are selectivelyExpand

The Role of Striatal Tonically Active Neurons in Reward Prediction Error Signaling during Instrumental Task Performance
The detection of differences between predictions and actual outcomes is important for associative learning and for selecting actions according to their potential future reward. There are reports thatExpand

Reward-related neuronal activity in the subthalamic nucleus of the monkey
The subthalamic nucleus is a key structure for motor information processing in the basal ganglia. Little is known about its involvement in other aspects of behavior such as motivation. WeExpand

Tonically active neurons in the striatum differentiate between delivery and omission of expected reward in a probabilistic task context
Tonically active neurons (TANs) in the primate striatum are responsive to rewarding stimuli and they are thought to be involved in the storage of stimulus–reward associations or habits. However, itExpand

Influence of spatial information on responses of tonically active neurons in the monkey striatum.
Previous studies have demonstrated that tonically active neurons (TANs) in the primate striatum play an important role in the detection of rewarding events. However, the influence of the spatialExpand

Influence of the predicted time of stimuli eliciting movements on responses of tonically active neurons in the monkey striatum
Changes in activity of tonically active neurons of the primate striatum are determined both by the behavioural significance of stimuli and the context in which stimuli are presented. We investigatedExpand

Motor impairments and neurochemical changes after unilateral 6-hydroxydopamine lesion of the nigrostriatal dopaminergic system in monkeys
Unilateral lesions of the nigrostriatal dopaminergic system were induced in five monkeys by intranigral injections of the neurotoxin 6-hydroxydopamine. Following the lesion, all monkeys showed aExpand

Responses of tonically discharging neurons in monkey striatum to visual stimuli presented under passive conditions and during task performance
To test whether the responsiveness of tonically discharging neurons from monkey striatum is dependent on the motor or rewarding features of the conditioned stimuli, we studied the responses of theseExpand

Influence of predictive information on responses of tonically active neurons in the monkey striatum.
Influence of predictive information on responses of tonically active neurons in the monkey striatum. J. Neurophysiol. 80: 3341-3344, 1998. We investigated how the expectation of a signal ofExpand
