Research Area

Information transfer between neurons takes place at the synapse. The wiring pattern among various types of neurons via specific synaptic connections is the basis of functional logic employed by the brain for information processing. Thus, detailed knowledge of neuronal networks is essential for understanding the wide range of brain functions. With special reference to the mouse and zebrafish olfactory system, we aim to elucidate the molecular and cellular mechanisms underlying the formation, maintenance, and plasticity of functional neural circuits. We will also focus on the identification and characterization of functional molecules involved in cell-cell interactions at the synapses in both the developing and mature brains.
