🧠💤 Can the unconscious brain still process meaning?

A remarkable Nature study used Neuropixels recordings from the human hippocampus during general anesthesia and found preserved oddball detection, semantic encoding, syntactic processing, and even prediction of upcoming words.

The anesthetized brain was not silent—it adapted, learned, and contextualized language despite loss of consciousness. These findings challenge classical theories tightly linking higher cognition to conscious awareness.
