Academic interests

Impact of axonal functions on neuronal network activities.

Plasticity and regulation of GABAergic inhibition.

Current Projects

Functional analysis of cortical interneuron axons. Inhibitory interneurons play a key role in several higher microcircuit functions, such as feedforward and feedback inhibition, high-frequency network oscillations, and temporal encoding of information in the brain. Many of these functions are critically dependent on the rapid and temporally precise release of GABA from inhibitory axon terminals. We study synaptic computation mechanisms in these interneuron axon terminals that are highly specialized in fast signaling.
