A single dose of the hallucinogen psilocybin dramatically alters brain chemistry. In a pilot study on male Wistar–Han rats, a 10 mg/kg dose of psilocybin increased the expression of most neuropeptides and specific serotonin 5-HT receptors (5-HT1A, 5-HT2A, 5-HT2B) within the hypothalamus. This neurochemical shift, observed in Neuroscience and Pharmacology, suggests how psilocybin, a key compound in Psychedelics and Drug Studies, influences neurotransmitter receptor activity. Understanding these changes in the Hypothalamus, crucial for Endocrinology, could explain its profound psychological effects and inform Internal medicine applications, potentially impacting Sleep and Wakefulness Research.

Prehospital Ketamine Administration in Benzodiazepine Refractory Status Epilepticus: A Case Series Review.
Prehospital emergency care – April 16, 2025
Summary
When seizures don't respond to standard treatments, ketamine shows remarkable promise, stopping seizures in over 90% of cases. This medication, already used by emergency responders for other conditions, proved highly effective when given to 42 patients whose seizures weren't controlled by conventional drugs. While some patients needed breathing support, the success rate suggests ketamine could be a game-changing option for emergency treatment of persistent seizures.
