Deep Brain Stimulation Effects on Reward Motivation
We will assess changes in Reward Motivation behavior with Deep Brain Stimulation on and off.
Patients with MDD or OCD
Patients with MDD or OCD who do not have a deep brain stimulator.
- Effort Expenditure for Rewards Task (EEfRT) [ Time Frame: 2 hours ]The EEfRT is a multi-trial computer-based task that assess an individual's willingness to expend effort for the chance to earn monetary rewards. We will assess whether stimulation of the Ventral Capsule/Ventral Striatum has an effect on behavior by executing this task with the DBS system on and off.
- Reward learning (clock task) [ Time Frame: 2 hours ]This task is an additional reward task that assesses reward learning. We will assess whether stimulation of the Ventral Capsule/Ventral Striatum has an effect on behavior by executing this task with the DBS system on and off.
