Topic: neuronal migration

Malformations of cortical development (MCDs) result from alterations of one or combined developmental steps, including progenitors proliferation, neuronal migration and differentiation. They are important cause of childhood epilepsy and frequently associate cognitive deficits and behavioral alterations. Though the genetic basis of MCDs have known prominent progress during the past decade, including the identification of somatic, mosaic mutations responsible for focal MCDs, the pathophysiological mechanisms linking malformations to epileptogenesis remain elusive. In this seminar I will present

The emergence of spontaneous activity in the form of synchronized bursting events (SBE) is considered to play a crucial role in activity-dependent development of neuronal networks. As inhibition matures, the spatiotemporal structure of activity becomes increasingly influenced by the balance between excitation and inhibition (E/I). Moreover, intricate interactions between excitatory (ENs) and inhibitory (INs) neurons may arise during their activity-dependent structural differentiation. However, how the resulting spatial embedding of INs and ENs in a network impacts on the spatiotemporal structu
