Ephaptic field research has undergone a remarkable evolution spanning over nine decades, from pioneering observations in the 1930s through a period of severe scientific skepticism in the mid-20th century to a contemporary renaissance driven by advanced computational modeling, measurement techniques, and new consciousness theories. This review traces the complete chronological development of...
Electromagnetic field (EMF) theories of mind/brain integration have been proposed to explain brain function for over seventy years. Interest in this theory continues to this day because it explains mind-brain integration and it offers a simple solution to the "binding problem" of our unified conscious experience. Thus, it addresses at least in part the "hard problem" of consciousness. EMFs are...
Background Ketamine is a clinical anaesthetic and a fast-acting, long-lasting antidepressant. Ketamine is known for its antagonistic actions on N-methyl-D-aspartate (NMDA) receptors, but mechanisms leading to antidepression are not clear. The present study examined synaptic, neuronal and circuit-level loci, the duration of ketamine’s actions, and the involvement of NMDA receptors in these actions.
