Summary

The study will evaluate whether sensory flicker can modulate neural activity of deep brain regions in humans, and whether it can have relevant effects on behavior. Moreover, it will compare those effects to the gold-standard method of modulating brain circuits, direct electrical stimulation of the brain (the same mechanism as deep brain stimulation), using a powerful within-subjects design.

Interventions

DEVICE

Customized version of DAVID device

A customized version of the DAVID device will be used to expose participants to sensory flicker. The device consists of opaque glasses containing LEDs to present flickering light, as well as earbuds or headphones to present flickering sound.

DEVICE

Blackrock CereStim

The Blackrock CereStim is a fully programmable neurostimulator. The current pulses generated by the Blackrock CereStim are intended to stimulate neurons in proximity to a set of electrodes.
