title: Reeler mutant mice exhibit seizures during recovery from isoflurane-induced anesthesia.
abstract: Reeler mice are a model of cortical malformation with enhanced seizure susceptibility. Data suggest that the propensity to anesthesia-induced seizures may be enhanced in animal models with developmental anomalies. Consequently, reeler mice were monitored behaviorally before, during and after isoflurane anesthesia. During recovery, 12% of reeler homozygotes had class I/II seizures while the remaining 88% exhibited convulsive seizures entailing opisthotonus and forepaw drumming. Similar behavior was not observed in controls. These data reveal that reeler mice display isoflurane-induced seizures and provide support for the hypothesis that developmental anomalies may predispose the central nervous system to anesthesia-induced seizures.
