New Imaging Technique Helps Explain Unconsciousness 78

smitty777 writes "A new imaging technique called fEITER (for functional Electrical Impedance Tomography by Evoked Response) attempts to explain the process of slipping into unconsciousness. The fEITER is a portable device that creates 3D imagery based on evoked potentials measured hundreds of times a second. The interesting finding from these studies is that unconsciousness appears to result from a buildup of inhibitor neurons. From the article: 'Our findings suggest that unconsciousness may be the increase of inhibitory assemblies across the brain's cortex. These findings lend support to Greenfield's hypothesis of neural assemblies forming consciousness.'"
