Microglia, the brain\'s “busy bees”, continuously survey the microenvironment by extending and retracting their ramified processes to maintain brain homeostasis [1, 2].Upon disease or injury, microglia quickly transform their morphology and extend their processes towards the disease/injury sites to clear damage [2].

In the current study,we sought to investigate whether T-type Ca2+ channels (TCCs) in the brain are involved in generating post-anesthetic hyperexcitatory behaviors (PAHBs).We found that younger rat pups (postnatal days 9-11) had a higher incidence of PAHB
