How neuronal circuitry in the brain is established during development and refined in the adult is a central unanswered question in neuroscience. Neural recognition molecules expressed on the neuronal surface are pivotal players in developing cortical circuits. Among the most relevant of these molecules to human disease are members of the NCAM and L1 family (L1, CHL1, NrCAM, Neurofascin). Each of these cell recognition molecules has established functions in axon guidance that mediate correct topographic synaptic targeting of axons, while exciting new findings reveal that they also have vital functions in regulating synaptogenesis and plasticity of cortical networks. Importantly, mutations in neural adhesion molecule genes may contribute to susceptibility to human neuropsychiatric diseases such as schizophrenia, autism spectrum disorders, and intellectual disability. To study the normal and abnormal function of neural cell adhesion molecules in brain development and function, our laboratory uses a multidisciplinary approach to generate and analyze novel mouse genetic models of neurodevelopmental disorders.
