Cortical inhibitory circuits in health and disease

Plasticity of inhibitory circuits
Circuit dysfunction in neurological disorders
Functional organization of olfactory cortex

How do neuroimmune interactions shape the plasticity of
inhibitory circuits in experience-dependent learning and in disease?

We strive to answer these questions by understanding how neural circuits are organized and represent information during sensory processing and learning in the mammalian cortex, with a focus on inhibitory circuits. We integrate in vivo and in vitro analysis of specific neural circuits by using a combination of electrophysiology, 2-photon imaging, opto-, chemo- & mouse genetics, confocal microscopy, sensory activity manipulation and disease models. Understanding the principles of how specific circuits are connected will lead way to development of therapeutics for various neuropsychiatric disorders like epilepsy, depression, Alzheimer's Disease, and schizophrenia.

olfactory bulb

Piriform cortex

Cajal's view of how the olfactory bulb is connected to the piriform cortex (1891). One of our goals is to understand the neural ciruitry of piriform cortex in terms of cell-type specific connection and function.
