[00:00:00]Can your brain [music] process sound even when you are under general anesthesia?

[00:00:04]A new study reveals that tiny clusters of neurons still respond to tones, surprising [music] sounds, and even spoken words.

[00:00:11]Researchers monitored brain cell activity in patients and found that certain auditory signals triggered clear electrical responses deep within the brain.

[00:00:20]These responses occurred without any sign of consciousness, [music] hinting at a hidden layer of sensory processing that processed despite the drugs.

[00:00:28]The discovery challenges our understanding of what it means to be unconscious and may help improve anesthesia monitoring in the future.

[00:00:36]Understanding this residual hearing could lead to safer surgical protocols and better care.
