I am focused on evaluating effective neuronal stimulation techniques for optimizing communication within neuronal networks. My research primarily employs optogenetic stimulation, alongside comparing with mechanical stimulation, to analyze their relative efficiency in modulating network activity. A key part of my work involves calcium imaging data analysis, using Channelrhodopsin 2 and genetically encoded calcium indicators (GECIs) like RCaMP, to investigate neuronal activity at a single-cell level. Additionally, I am studying biochemical pathways associated with neuronal or synaptic plasticity to uncover mechanisms underlying memory formation and network adaptation. A novel dimension of my research explores how local field potentials (LFPs) generated from synchronous neuronal activity within one network can influence communication in physically separated yet functionally related networks. By investigating the propagation of LFPs and their impact on neighboring networks, I aim to deepen our understanding of inter-network signaling and communication. This work has broad implications for advancing our knowledge of network dynamics in the brain, offering potential applications in both neuroscience research and neuroengineering technologies.
