Journal of Neuroscience<\/p>\n<p><strong>Abstract<\/strong><\/p>\n<p><strong>DMT-Induced Shifts in Criticality Correlate with Self-Dissolution<\/strong><\/p>\n<p>Psychedelics profoundly alter subjective experience and brain dynamics. Brain oscillations express signatures of near-critical dynamics, relevant for healthy function. Alterations in the proximity to criticality have been suggested to underlie the experiential and neurological effects of psychedelics.<\/p>\n<p>Here, we investigate the effects of a psychedelic substance (DMT) on the criticality of brain oscillations, and in relation to subjective experience, in humans of either sex.<\/p>\n<p>We find that DMT shifts the dynamics of brain oscillations away from criticality in alpha and adjacent frequency bands. In this context, entropy is increased while complexity is reduced.<\/p>\n<p>We find that the criticality shifts observed in alpha and theta bands correlate with the intensity ratings of self-dissolution, a hallmark of psychedelic experience.<\/p>\n<p>Finally, using a recently developed metric, the functional excitatory-inhibitory ratio, we find that the DMT-induced criticality shift in brain oscillations is towards subcritical regimes.<\/p>\n<p>These findings have major implications for the understanding of psychedelic mechanisms of action in the human brain and for the neurological basis of altered states of consciousness.<\/p>\n","protected":false},"excerpt":{"rendered":"Summary: A new study using DMT as a scientific tool reveals how psychedelics alter the brain\u2019s alpha-wave dynamics&hellip;\n","protected":false},"author":3,"featured_media":402539,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[11],"tags":[827,41991,190390,23642,210,18769,1184,517,829,23703,190391,831,39648,1737,39649,159,108115,67,132,68],"class_list":{"0":"post-402538","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-health","8":"tag-brain-research","9":"tag-consciousness","10":"tag-dmt","11":"tag-ego-dissolution","12":"tag-health","13":"tag-identity","14":"tag-medicine","15":"tag-mental-health","16":"tag-neurobiology","17":"tag-neuropharmacology","18":"tag-neuropsychopharmacology","19":"tag-neuroscience","20":"tag-psychedelics","21":"tag-psychology","22":"tag-psychopharmacology","23":"tag-science","24":"tag-sfn","25":"tag-united-states","26":"tag-unitedstates","27":"tag-us"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/115607773207565359","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/402538","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=402538"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/402538\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/402539"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=402538"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=402538"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=402538"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
