«The fact that we can induce a short seizure, of approximately 1 to 3 minutes long,
with the exact timing of an
electrical pulse, and that these worms react well to antiepileptic drugs, makes this new assay a perfect model for high - speed drug screens in multi-welled plate readers,» said Ken Dawson - Scully, Ph.D., corresponding author and associate professor in the Department of Biological Sciences and associate director of the FAU Brain Institute.
