Biography/Curriculum Vitae:

Research Interests:
Identification of genes that contribute to cerebral development and cerebral hemispheric specialization in humans

Narrative of Current Research Efforts:
The major focus of Geschwind's research is to identify genes that contribute to cerebral development and cerebral hemispheric specialization in humans. He is using multidisciplinary approaches including genetic linkage mapping in patients with familial forms of dyslexia and language disorders, and behavior analysis coupled to comparative genomic hybridization in Klinefelter's syndrome to identify X chromosome regions contributing to dyslexia/dysphasia in Klinefelter's patients.

To find genes underlying human language related brain asymmetries, the Geschwind laboratory has applied representational difference analysis (RDA) coupled to DNA microarray screening to identify genes that are differentially expressed in the right and left hemispheres in the developing human embryonic brain. Geschwind's laboratory has recently defined the first chromosomal locus for an enigmatic neuropsychiatric disorder, Fahr's disease. Work in other neurodegenerative disorders, including uncovering the mutational basis of frontotemporal dementia, is ongoing.

The premise underlying much of Geschwind's research is that genetic contributions to the development of brain structures are fundamentally related to human behavior. An exciting future direction of this work involves the coupling of neuroimaging and quantitative genetic approaches to identify genetic contributions to brain structure variations.
