Summary
The neuroepithelium (NEP) contains the embryonic neural stem cells essential for the production of all neurons in the adult brain. Failure in NEP function leads to devastating neural tube defects and syndromes such as epilepsy, schizophrenia, and mental retardation. This project will identify the molecular mechanisms regulating NEP stem cell activity and the birth of new neurons in the embryonic neocortex.
Understanding The Embryonic Origins Of Cortical Malformations

Summary
Cortical malformation leads to mental retardation and epilepsy. Identification of the aberrant developmental processes contributing to these devastating syndromes is essential for accurate clinical assessment and development of novel therapeutics. Here we investigate a developmentally important receptor, Neogenin, which when mutated, leads to cortical malformations. Determining how Neogenin functions is expected to uncover new signaling pathways contributing to these malformations.

Summary
The essential steps in forming a normal functioning brain occur during life as an embryo. If these processes go haywire, there can be serious repercussions for life after birth. This project seeks to understand how the brain forms during embryonic stages so that better treatments and procedures can be developed to deal with developmental problems.
Dissecting The Role Of RYK In Cortical Neuron Specification And Schizophrenia

Summary
Correct production of neuronal subtypes within the neocortex is essential for coordinated brain activity and higher-order functions. Understanding how newborn neurons decide which subtype to adopt is critical as incorrect neuron identity has profound consequences for neocortical function and is associated with schizophrenia and mental disability. We have recently linked one molecule, RYK, to schizophrenia. In this project we will explore how Ryk influences cortical neuron fate.
