Different general anesthetics affect consciousness and memory in different ways

Caption

A mouse brain section highlighting the hippocampus is overlaid with the molecular structures of the anesthetics isoflurane (purple), medetomidine/midazolam/fentanyl (orange), and ketamine/xylazine (red). The four panels in the lower part show two-dimensional maps of active neurons in the same hippocampal region during wakefulness (top left) and under the different anesthetics indicated above. Colors indicate the respective anesthetics. Neurons with correlated activity are connected by black lines.
