Research Activity

GABAergic interneurons play critical roles in the central nervous system, providing the greatest source of synaptic inhibition and regulating vital aspects of neuronal network dynamics.  

A detailed knowledge of the large diversity and specific functions of interneurons is essential to understand the pathogenic mechanisms of several neurological disorders such as epilepsy, Parkinson’s disease, schizophrenia, and many others.

The ability to assess the involvement of different neuronal subpopulations in brain functions has represented one of the greatest challenges in neurobiology, but new research methods introduced in recent years―such as optogenetics and in vivo imaging techniques―are opening important novel routes of investigation


Our studies focus on the role of different types of GABAergic interneurons in animal models of neurological diseases. We are particularly interested in malfunctioning of basal ganglia synaptic microcircuits, mechanisms of initiation of epileptic tonic-clonic seizures, and synaptic defects involved in neuroinflammation and multiple sclerosis.

By using optogenetic tools combined with electrophysiological methods such as patch-clamp and local field recordings, we investigate how optical stimulation of specific interneuronal subtypes affects the electrical activity of principal neurons in basal ganglia and cerebral cortex. We also study the electrophysiological properties of neurons differentiated from induced pluripotent stem cells (iPS) obtained from human patients affected by multiple sclerosis and neurodegeneration with brain iron accumulation (NBIA).
