What it means to be conscious is more than just a philosophical question. Researchers continue to investigate how conscious experience arises from the electrochemical activity of the human brain. The answer has important implications for the way brain health is understood, from coma, wherein a person is alive but unable to move or respond to his or her environment, to surgical anesthesia, to the altered thought processes of schizophrenia.
Dr. Duan Li published a Reader’s Toolbox article in Anesthesiology, which elaborates on brain complexities and anesthesia for the sake of anesthesiologists
A complex system is often associated with the emergence of new phenomena from the interactions between the system’s components.
Conscious access to sensory information is likely gated at an intermediate site between primary sensory and transmodal association cortices, but the structure responsible remains unknown.
CCS Scientific Director George Mashour publishes new paper in elife that examines how the brain recovers from unconsciousness after anesthesia
Understanding how the brain recovers from unconsciousness can inform neurobiological theories of consciousness and guide clinical investigation.
Anesthetics are known to disrupt neural interactions in cortical and subcortical brain circuits. While the effect of anesthetic drugs on consciousness is reversible, the neural mechanism mediating induction and recovery may be different.
Shamanic trance is an altered state of consciousness used by shamanic practitioners to glean information to be used for the physical, psychological, or spiritual healing of others.
Recent resting-state functional MRI (fMRI) studies have revealed that the global signal (GS) exhibits a nonuniform spatial distribution across the gray matter.
