By considering brain areas associated with imagination, researchers are able to look back over millions of years to find out how imagination first evolved in humans.
Do people really have a "sixth sense"? Researchers evaluate how intuition and visions, often induced, are part of our conscious experience.
As many as one in four patients who receive anesthesia may suffer accidental awareness during their procedure. Researchers have identified specific brain structures that may predict whether a person will experience accidental awareness under anesthesia. The findings will help identify patients who require higher than average doses of anesthesia.
Using neuroimaging, researchers identified three cortical gradients that appear to align with dimensions of consciousness.
A single psychedelic experience increases beliefs about consciousness, meaning, purpose, and a range of nonphysicalist beliefs.
Tracking eye movements as a person views an image of a face in different lights provides vital clues about visual perception and consciousness overall.
The brain responds more strongly to information that is deemed social as opposed to non-social.
Investigating how psychedelics such as psilocybin act on serotonin receptors, researchers shed new light on how the drugs affect consciousness and assist in treating a range of mental health disorders.
The claustrum coordinates networks associated with executive commands to work together to accomplish the many cognitively demanding tasks we perform on a moment-to-moment basis.
Study suggests quantum processes are part of cognitive and conscious brain functions.
Under anesthesia, neuron assemblies that respond to sound become indistinguishable from spontaneously active neurons. Findings suggest the state of unconsciousness produced by anesthesia forces the cerebral cortex to mask sensory input with spontaneous neural activity.
A new theory of consciousness suggests decisions are made unconsciously, then about half a second later, they become conscious.
