Giving up the theory that consciousness is like a "ghost in the machine" to focus on the neurobiology of brain mechanisms behind conscious awareness is an essential step to better understand the human mind, researchers argue.
Researchers believe they have identified specific neurons that are responsible for conscious awareness. Previous studies have implicated both thalamocortical circuits and cortico-cortico circuits in consciousness. The new study reports these networks intersect via L5p neurons. Directly activating L5p neurons made mice react to weaker sensory stimuli. The researchers say if consciousness requires L5p neurons, all brain activity without them must be unconscious.
The common myth that Anne Boleyn tried to speak after her untimely demise at the hands of her executioner may have scientific evidence behind it. Researchers explore how consciousness may remain intact for a period of time after death, and what that may mean for medical sciences.
