Purpose
The primary aim of this study is to test the effects of excitation of ventral striatal circuitry via DBS (e.g. DBS-on versus DBS-off) on reward motivation. The investigators predict that stimulation will increase subject willingness to expend effort for rewards and facilitate motivation for reward learning. The investigators further predict that individual differences in the effects of DBS on reward motivation as will be associated with effects of DBS treatment on anhedonic symptoms.

Primary Outcome Measures:
- Effort Expenditure for Rewards Task (EEfRT) [ Time Frame: 2 hours ] [ Designated as safety issue: No ]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.
Secondary Outcome Measures:
- Reward learning (clock task) [ Time Frame: 2 hours ] [ Designated as safety issue: No ]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.
