Dexmedetomidine Alleviates Cognitive Impairment by Promoting Hippocampal Neurogenesis via BDNF/TrkB/CREB Signaling Pathway in Hypoxic–Ischemic Neonatal Rats

Hypoxic–ischemic brain damage (HIBD) was induced in postnatal day seven rats using the Rice-Vannucci method, and dexmedetomidine (25 μg/kg) was administered intraperitoneally immediately after the HIBD induction.
