Dynamic Memory Lab (Ranganath)

Dr. Ranganath's research concerns the neurocognitive structure of human memory and executive control. One set of studies currently underway concerns the relationship between short-term, or working memory, and long-term memory.

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.
