General anesthesia can occur without causing amnesia.
General anesthesia does not always completely abolish memory formation or sensory processing, as evidence indicates that implicit and weak explicit memory can sometimes occur.
The retrieved papers provide consistent evidence that information processing and forms of memory formation can occur during general anesthesia, supporting the claim that general anesthesia can occur without causing complete amnesia. Papers [0], [1], and [6] show that sensory stimuli are processed and that memory traces or implicit/explicit memory formation can be detected even under general anesthesia. Therefore, the claim is supported.

Demonstrates that a weak form of explicit memory can occur during light general anesthesia even when patients cannot consciously recall the events.

Establishes that memory formation is possible during general anesthesia, including at hypnotic depths considered adequate.

Plasticity and language in the anaesthetized human hippocampus.. 2026. https://doi.org/10.1038/s41586-026-10448-0
Shows that complex sensory processing, oddball discrimination, and semantic processing persist in the hippocampus during general-anesthesia-induced loss of consciousness.
