Current Research

Morphogenic Impact of Excitatory-Inhibitory Interaction on the Structure of Neuronal Networks

Our goal is to gain a mechanistic understanding of the interplay between inhibitory and excitatory neurons in the activity-dependent self-organization of neuronal network structure. We will construct theoretical and computational frameworks for modeling mesoscale neuronal network development accounting for the interplay among homeostatic growth, excitatory and inhibitory activity, and morphogenetic processes. In principle, unraveling the dynamical structural, functional, and behavioral aspects shaping nontrivial emergent features of developing neuronal networks. This project is in collaboration with experimental PhD study with neuronal networks developing in vitro using electrophysiology, fluorescence imaging, optogenetic manipulation, and morphometric analyses. Insights from in-vitro experiments will help constrain biologically plausible and interpretable models consistent with quantitative measurements from these networks.
