Research Topics
A translational approach to development of electrical brain stimulation for cognitive enhancement
The goal of this project is to develop a monkey model of tDCS in order to clarify how tDCS affects activity and synchrony of neural populations, and to validate noninvasive biomarkers of tDCS effects for use in human studies.
Role: co-Principal Investigator
Individualized tACS to enhance oscillatory activity and cognitive performance in patients with schizophrenia
The goal of this pilot project is to assess the feasibility of tACS as a method to enhance cognition in patients with schizophrenia.
Role: Principal Investigator
Decoding and Enhancing Neural Mechanisms for Episodic Memory
The goal of this project is to determine the causal role for theta oscillations in episodic memory. Three methods are proposed—transcranial alternating current stimulation, sensory entrainment, and reward motivation—to manipulate theta activity and determine the effects on memory for contextual details and corresponding effects on brain activity measured by fMRI and EEG.
Role: Principal Investigator
Neural Mechanisms of Memory Dysfunction in Schizophrenia
The goal of this proposal is to use multimodal imaging including magnetic resonance spectroscopy (MRS), electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) to determine the causes of memory deficits in schizophrenia.
Role: Principal Investigator
Representation and binding of spatiotemporal episodic memories in the human hippocampus
This project investigates how the human hippocampus represents space and time in episodic memory.
