Research Summary

Relationship of Research to Neurological Disease:

Developmental processes may underlie a number of neurological problems. These relate to normal and abnormal development. Many childhood behavioral disabilities may relate to underlying problems in brain development. We find, for instance, that raising neurons from any region of the brain in the absence of glutamate neurotransmitter stimulation results, at a later point in neuronal development, in a hypersensitivity to glutamate, neuronal hyperexcitability (seizure-like activity), and cell death. These problems can be reduced to varying degrees by a number of peptide modulators of glutamate release and response. Another example of clinical relevance is our finding that the primary inhibitory transmitter in the brain, GABA, has excitatory actions after neuronal trauma, potentially resulting in additional secondary brain injury due to the potential loss of inhibition in affected brain circuits. An important theme in the context of this research program is the parallel that occurs between normal development and recovery after neuronal injury. Understanding normal brain development facilitates the understanding of the steps that may occur as neurons recovery from injury.

Extensive Research Description

Current Research Program

We are particularly interested in the mechanisms where neurotransmitters in early development may play a role in establishing and stabilizing functional neuronal circuits. To this end we use a variety of approaches including electrophysiology, tissue culture, molecular biology, ultrastructural immunocytochemistry, and digital imaging to study the general question from converging perspectives relating both to neuronal structure and function. A particular area of interest within the brain is the hypothalamus that acts as a homeostatic regulator controlling the endocrine system, biological rhythms, cardiovascular system, and general autonomic tone.
