Time to Wake Up! The Ongoing Search for General Anesthetic Reversal Agents.

How general anesthetics work remains a topic of ongoing study. A parallel field of research has sought to identify methods to reverse general anesthesia. Reversal agents could shorten patients' recovery time and potentially reduce the risk of postoperative complications.

Proportional Downscaling of Glutamatergic Release Sites by the General Anesthetic Propofol at Motor Nerve Terminals.

Propofol is the most common general anesthetic used for surgery in humans, yet its complete mechanism of action remains elusive. In addition to potentiating inhibitory synapses in the brain, propofol also impairs excitatory neurotransmission. We use electrophysiological recordings from individual glutamatergic boutons in male and female larval motor nerve terminals to characterize this effect.
