Research from Baylor College of Medicine shows that the human hippocampus remains active during propofol-based general anesthesia, capable of oddball discrimination and semantic processing. By recording brain activity in patients with drug-resistant epilepsy, the team identified neural responses aligned with auditory tones and semantic meaning from listening to podcasts. Results indicate anesthesia does not fully eliminate hippocampal representational plasticity and suggest cognitive processes may persist without consciousness, raising meaningful questions about brain function during anesthetic states.
