Genetic cues responsible for interneuron migration and layering in the neocortex

Funded Activity Summary

Understanding how the brain is assembled, and the genes that drive this process, will provide insights into two exciting areas of current neuroscience. First, it will clarify how we differ from other species, and illuminate the evolutionary concepts underscoring functional specialization. Secondly, there are sound health-related reasons to study brain development. Proper brain function requires the proper assembly of neurons and the establishment of circuitry. Defective generation of neurons in sufficient numbers, or impediments to neuron migration to proper destinations are certain recipes for neurological disorders, including epilepsy and mental retardation. In this application, we will study how neurons are assembled in the cortex. We will focus on a subpopulation known as interneurons that are vital for toning down electrical discharges from excitatory neurons. We will investigate how these neurons are able to migrate long distances to settle into defined layers of the cortex. Mutant mice with deleted genes have a defect in this process and the aim of this project will be to study the precise mode of action for some of these genes.
