High throughput genetic and genomic analysis of brain circuits involved in neurological and psychiatric disease.
The basal ganglia and cerebellum each contain discrete anatomical circuits that process information received from the cerebral cortex and other subcortical structures, and send the results of this processing back to the same cortical areas that they receive input from. Circuits involved in motor and cognitive function are largely separate, and appear to be selectively involved in certain neurological or psychiatric disorders. Using microarray technology, experiments are being carried out to identify the specific genes involved in the establishment and maturation of these circuits. These data are contrasted with those obtained from brain and peripheral biomarker tissues from individuals with neurological and psychiatric disorders known to affect these circuits, as well as genetic and environmental models of these disorders. Most of the work in the lab is focused on four disorders: schizophrenia, Parkinson's disease, attention deficit hyperactivity disorder (ADHD), and alcohol abuse. Each of these illnesses affects motor and cognitive behavior through actions on different components of the basal ganglia or cerebellum. Validation and follow-up studies utilize in situ hybridization, in situ transformation of cultured cells and tissue slices, as well as real time PCR, western blot, and immunohistochemistry.
The search for genes that cause neurological and psychiatric disorders.
The laboratory has also been extensively involved in the search for genes which cause schizophrenia, ADHD and Parkinson's disease, by comprehensive monitoring of gene expression, DNA methylation, copy number, and single nucleotide polymorphism (SNP) genotypes. Much of this work involves classical linkage and association analyses, but extends to include extensive functional characterization of candidate genes or sequence alterations that are identified.
