NEW TEN-PART AUDIO SERIES about #PSYCHEDELICS
Out now on BBC Sounds - and other podcast spaces.

Co-written & presented by the beautifully curious @timhayward.bsky.social
Production, sound design and mix by me.

It's been a fascinating and challenging process to get here...

I do hope you'll listen.

How could a state of deconstructed consciousness correspond to cortical disinhibition? Working hypothesis: an overflooding of attentional/perceptual resources leads to the inability of the mind/brain to process such information and make meaningful ‘gestalts’. 7/n
christimmermann.bsky.social
EEG revealed the 5-MeO experience to be characterised by a broad reduction of alpha and posterior beta power. These findings are consistent with those we have found in previous research with DMT and other psychedelics and point towards a state of cortical disinhibition. 6/n

Doubling on the idea of 'deconstructed consciousness', analyses indeed revealed these peak experiences lacked embodied and narrative dimensions of the self, while also being devoid of thoughts and phenomenal distinctions while being disconnected from the environment. 5/n
christimmermann.bsky.social
The often-used questionnaire ASC mostly did not capture these peak experiences (black dots below), confirming our previous call to employ advanced phenomenology in consciousness studies (pubmed.ncbi.nlm.nih.gov/36566091/). 4/n
christimmermann.bsky.social
We characterised the different phases of the experience and its transitions (whenever we could). For about 1/3 of experiences, we identified an ‘everything/nothing’ stage where no sense of self or other contents were reported but awareness was preserved. 3/n
christimmermann.bsky.social
5-MeO is attractive for the science of consciousness as reports claim it dissolves time, space, self, and other contents resulting in so called ‘pure awareness’. We went to retreats in the Netherlands and Spain were participants had it and assessed EEG and phenomenology. 2/n
christimmermann.bsky.social
Our new paper - the first peer-reviewed brain and phenomenological examination of 5-MeO-DMT is out in Neuro of Consciousness.

TLDR: We tested whether ‘the mount Everest’ of psychedelics could induce a complete state of consciousness deconstruction while preserving awareness. 1/n

Age-related differences in 1/f aperiodic EEG/MEG signals can be driven by cardiac rather than brain activity 👇

Age-related changes in “cortical” 1/f dynamics are linked to cardiac activity

Maybe a good time to remember that mice have tiny hyperconnected brains. An estimated 97% of all possible connections between brain areas exist in mice, vs ~62% in macaques and marmosets.

No wonder everything is everywhere in mice, they have all-to-all connectivity!

2/ Our comment is a response to both the charge from 'IIT-concerned et al' that IIT is pseudoscientific (we disagree) www.nature.com/articles/s41... and to the response by Tononi et al www.nature.com/articles/s41...

Congrats to Lisa Luan for a successful PhD defence leading our extended DMT studies at @imperialcollegeldn.bsky.social . Very proud to call her my first completed PhD student and in awe of how she managed to meticulously carry out some of the most extreme studies one could think of

Benny Shanon, one of the pioneers of modern psychedelic research, has recently passed away. If you haven't done so, check out his book Antipodes of the Mind, one of the most influential and beautiful books I have read. May his contributions carry forward in our work and explorations of consciousness

Hi everyone, we have published a new paper showing that #psilocybin increases emotional #empathy in patients living with depression for at least two weeks after a single administration. If you are interested in #psychedelics and #social cognition, take a look here: www.nature.com/articles/s41...

Does the culture you grow up in shape the way you see the world? In a new Psych Review paper, @chazfirestone.bsky.social & I tackle this centuries-old question using the Müller-Lyer illusion as a case study. Come think through one of history's mysteries with us🧵(1/13):
