Research Summary

The goal of my laboratory is to determine what goes wrong in neurodegenerative disorders at the circuit level during the behaviors that matter most to the human disease. We tackle this problem using innovative optical tools to image and manipulate brain activity during critical behaviors in mouse models.

One of focuses of my laboratory is Alzheimer’s disease – the most common cause of dementia. Memory loss and cognitive decline in Alzheimer’s disease is likely due to circuit level dysfunction, but the nature of this dysfunction is unknown. We want to address the fundamental question: How does Alzheimer’s disease disrupt circuit activity during learning and memory retrieval? Specifically, we image neuronal ensembles in the hippocampus during spatial navigation and memory tasks using two-photon calcium imaging and freely moving miniature microscope imaging technologies. Furthermore, using simultaneous two-photon imaging and holographic two-photon optogenetic, we aim to determine the causal link between neuronal ensembles and learning and memory.

Another focus of my laboratory is to investigate the neural mechanisms of perceptual learning. Perceptual learning is a progressive improvement in performance on sensory tasks. Investigating the neural mechanisms of perceptual learning will enhance our understanding of plasticity in the adult brain and provide novel insights into learning disability. To tackle this problem, we focus on the primary visual cortex and determine network-level modifications in response to visual stimulation during perceptual learning as well as the modifications in intrinsic activity in the cortex. We also investigate a mechanistic approach to directly stimulate V1 ensembles to accelerate perceptual learning using a holographic two-photon optogenetic.
