Dr. Schwartzkroin studies cellular mechanisms that control/modulate excitability in the brain, particularly those involved in epilepsy and seizures, as well as the neurobiology of pediatric epilepsies, particularly those associated with abnormal brain development and cortical dysplasia. Dr. Schwartzkroin?s laboratory is interested in issues of neuronal plasticity, ranging from those processes that underlie normal learning to those involved in the generation of pathological activities such as epileptic seizures. The lab has focused on cellular and circuit properties of the hippocampus, a region implicated in both higher brain functions (such as learning and memory), as well as in neuropathologies associated with epilepsy, traumatic brain injury, and other neurological disorders. The laboratory employs a variety of experimental techniques, including: electrophysiology of individual neurons in in vitro preparations; stimulation and recording in intact animal seizure models; morphological and immunocytochemical (light and electron microscopic) assessment of brain tissue; and behavioral/electrophysiological/morphological characterization of genetically manipulated animals (rats/mice).
Currently, Dr. Schwartzkroin's laboratory focuses on two major sets of research questions: (1) How do developmental brain abnormalities lead to seizures and epilepsy? Using animal models of cortical dysplasia, the laboratory uses cellular and intact animal electrophysiological analyses to determine changes in cellular or circuit properties that might underlie seizure/epilepsy development. Neuroanatomical staining procedures are used to establish structure-function relationships. (2) What genes contribute to seizure susceptibility and/or to the development of an epileptic state? Using animal models in which genes have been modified or deleted, the laboratory studies seizure propensity and seeks the underlying bases for that sensitivity.
In addition to his epilepsy-related research, Dr. Schwartzkroin has been active in a number of major editing projects: Co-Editor-in-Chief of the journal Epilepsia, and Editor-in-Chief of The Encyclopedia of Basic Epilepsy Research.
