The very first big deal 3-D images of the brain as it slips into unconsciousness.
A new technique allows researchers to view real-time 3-D images of a patient undergoing anesthesia using the drug propofol, and the findings show that consciousness isn’t suddenly switched off, but rather fades as though a dimmer is being dialed down. Via
This new technique which basically sends tiny electrical currents through the skull is called the functional Electrical Impedance Tomography of Evoked Response (fEITER). In this study (lead by Brian Pollard of Manchester U.), the results suggest that there are several different layers of consciousness… not an “on/off switch” as typically assumed--and that consciousnesses may lie in the communication between many parts of the brain. So, if this brain is unconscious, why does it look so much is happening?
When inhibition is inhibited, you first move into a stage of excitation or mania and then you then begin to inhibit the excitation and the patient becomes more sedated and loses consciousness.
Meaning? it’s showing the all the massive action, or talking between the different areas, arresting each other’s circuits. Neato!
