Research summary
A number of interneuron
subtypes exist within the brain that inhibit different cellular compartments
and cell types and form very different synapses with their post-synaptic targets.
My lab is interested in studying the role of these interneuron classes in
regulating network activity in neocortical and hippocampal microcircuits, both
in physiological and epileptic conditions. To study this, we have developed 2
complementary approaches: (A) In ex-vivo
cortical slices, we combine patch-clamp recordings with Cre-Lox technology and a
variety of optogenetic tools or fluorescent tags in order to record and
manipulate specific groups of interneurons and assess their net inhibitory action
on the network. (B) In in vivo awake
animals, we apply our findings on interneuron physiology to study their role in
epilepsy and design protocols to test whether they can be used to stop
seizures. For this, we use a combination of electrocorticogram recordings and
either two-photon imaging techniques (GCaMP6, iGluSnFR, iGABASnFR) or
closed-loop optogenetic stimulation in animals experiencing
experimentally-induced seizures.
