Supporting evidence includes anesthesia research showing that drugs with very different molecular mechanisms can all produce unconsciousness while disrupting large-scale brain-wave organization.<\/p>\n<div class=\"more-link-wrapper\"> <a class=\"more-link\" href=\"https:\/\/lifeboat.com\/blog\/2026\/08\/cognition-and-consciousness-arise-from-analog-computations-says-new-theory\">Continue reading \u201cCognition and consciousness arise from analog computations, says new theory\u201d | &gt;<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>A new theory from neuroscientists at MIT\u2019s Picower Institute proposes that cognition and consciousness may depend not only on neurons and synaptic connections, but also on the traveling electrical waves generated by neural activity.
