Abstract
En 中文
Emergence from anesthesia involves structured cortical transitions that are visible on the density spectral array (DSA). The open crocodile upper jaw pattern, defined by the separation of slow delta and re-emerging betagamma activity, has gained attention as a physiological marker and a teaching tool. Here, we contextualize this visual mnemonic phenomenon within established neurophysiology and emphasize its importance in understanding recovery from general anesthesia. This article provides new value by formally contextualizing an informal EEG teaching cue within established neurophysiology and translating it into a practical, clinically interpretable framework.
