We are a human systems neuroscience lab studying brain electrophysiology and behavior in patients undergoing surgery for epilepsy, movement disorders, and psychiatric disease. The goal of our work is to facilitate the development and optimization of electrical and biological brain modulation therapies, by filling critical gaps in our understanding of human brain function.

Basal Ganglia-Cortical Dynamics in Human Behavior 

Intraoperatively, we collect simultaneously recorded cortical ECoG, subcortical MER/LFP, and behavioral data to study interactions between the cortex and basal ganglia that encode specific components of motor control.

Closed-Loop Brain Stimulation for Epilepsy

The lab's initial work in brain stimulation for epilepsy involved sensing-enabled DBS (PC+S and RC+S) in a nonhuman primate with idiopathic epilepsy. Subsequently, in order to better understand data recorded during responsive neurostimulation in our epilepsy patients, we built BRAINStim, a platform for Biophysically Rational Analysis and Informed Stimulation.

Computational Neuroscience of Language Processing 

In this project led by Ev Fedorenko, we are collaborating to study neural responses to language stimuli using intracranial recordings, in combination with the recent advances in computational neuroscience and machine learning, in a quest to understand human linguistic ability.


Mapping the Olfactory Perception Network

With funding from Lawnboy Ventures, we are using intracranial LFP recordings to map the electrophysiological correlates of odor perception, with a goal of defining network signatures of odor categories that can be recapitulated via electrical stimulation. The goal of this project is to development an olfactory prosthesis for patients with anosmia. 

Clinical Innovation in Functional Neurosurgery

The lab's resources, including surgical databases, are leveraged to innovate and advance neurosurgical strategies and technical approaches to better treat epilepsy, movement disorders, and other brain diseases.
