New Study Challenges What We Know About Consciousness and the Brain

A Baylor College of Medicine study found that hippocampal neurons in anesthetized epilepsy patients still responded to sounds and language.

The brain not only detected words, but also showed signs of predicting what might come next, despite the patients being unconscious.

The results suggest some learning and predictive processing can continue without conscious awareness.

The findings could reshape theories of consciousness and help guide future brain-computer interfaces and speech-recovery tools.
