Researchers affiliated with MIT argue that transcranial focused ultrasound—a noninvasive technique that can modulate activity in deep brain regions—could enable more direct, cause-and-effect tests of how conscious experiences arise. In a “roadmap” review in *Neuroscience & Biobehavioral Reviews*, they describe experimental approaches aimed at distinguishing between competing accounts of where and how awareness is generated in the brain.
A mathematical study concludes that consciousness cannot arise purely from quantum processes. Researchers at Chapman University found that the no-cloning theorem prevents the information copying required for agency.

Researchers at Baylor College of Medicine have found that the brain continues advanced language processing even during general anesthesia. Patients under unconsciousness distinguished parts of speech and anticipated upcoming words in stories. The results, published in Nature, challenge prior views on consciousness and cognition.
