"Catch me if you can" - locating the "Black Sheep" neurons after early-life seizures.

Unprovoked seizures in early life are one of the most severe conditions in pediatric neurology, and are often associated with long-lasting cognitive and behavioral deficits, as well as pharmacoresistant epilepsy in adulthood in some conditions. Unillustrated mechanisms greatly restrict the development of preventive strategies for early-life seizures (ELSs) related neuronal impairments. The recent groundbreaking study published in The Journal of Clinical Investigation represents a giant leap forward in understanding the complex pathogenesis mechanism and developing targeted therapies for ELS related neuronal impairments. The authors conducted elegant experiments to locate the activated pyramidal neuron subpopulation in the hippocampus and demonstrated the altered functions of (α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid)-type glutamate receptors (AMPARs). And we believe that the conclusions of this study may assist in further translational efforts to identify preventive targets for neurological disorders associated with early life seizures and propose new avenues for further exploration in this field.
