 Brain functions, ranging from simple reflexes to complex behavior, rely on the precise wiring of millions of neurons, or nerve cells. These neurons communicate with each other through synapses, which are highly specialized structures that mediate the transmission of information from one nerve cell to another. Synapses are established during development, as well as in the adult brain, and are remarkably plastic, undergoing constant remodeling (or synaptic plasticity) in response to experiences while communicating with the outside world. Dysfunction of neuronal circuits leads to numerous nervous system disorders including mental retardation, schizophrenia and autism spectrum disorders. To understand how the dysfunction of neuronal circuit contributes to the wide spectrum of nervous system disorders, it is important to perceive how synapses are formed, maintained, and function in a non-pathological setting. Towards this fundamental problem of neuroscience, our laboratory investigates novel epigenetic mechanisms involving non-coding RNAs and the Ubiquitin Proteasome System that fine-tune synapse development and synaptic plasticity.


We employ a wide range of biochemical, cell biological, and whole-cell patch clamp recording and use neurons from rat or mouse brain in primary culture or in vivo to address the following topics.


  • Molecular control of synapse formation by non-coding RNAs and the Ubiquitin Proteasome System
  • microRNA-mediated regulation of synaptic plasticity

  • From Stem Cell to Behaviour: Role of microRNA –mediated gene expression system in adult neural stem cells and its implication in development and function of feeding circuitry
