Researchers have mapped how propofol, a widely used anesthetic, alters brain connectivity to induce unconsciousness. Using fMRI, they found that propofol disrupts connections in the thalamus, reducing complex information processing and limiting sensory integration.

Researchers have discovered that nondeceptive placebos—placebos given with the full knowledge that they are placebos—can effectively manage stress, even when administered remotely. In a two-week randomized controlled trial, participants experiencing prolonged stress were divided into two groups: one group received nondeceptive placebos, while the other served as a control.
