This study shows that spreading depolarizations (SDs) are associated with seizure termination in both human and rodent models, with SDs reducing seizure duration and delaying subsequent events.

The paper shows that two optogenetic ion pumps, halorhodopsin and archaerhodopsin, cause different secondary K+ redistribution patterns after activation.

This paper introduces a rat model of birth asphyxia where seizures occur after, not during, hypoxia, and shows that intermittent hypoxia promotes neuronal hyperexcitability leading to seizures.

The paper investigates brain pH and PO2 changes in a rodent asphyxia model, finding that hypercapnia restores brain PO2 and protects against acidosis, unlike hypoxia.
