Hmmm.

New paper! Led by dagreat @healey_evan we publish the first pharmacological psychedelic study of the @the_ccclab along with @cocucolab where we unravel the neurophenomenology of DMT. @CambPsych @CamNeuro @Exactas_UBA.

This lovely work complements beautifully with @ArziAnat 's .where we demonstrate a state-, stimulus- and time-dependent functional reorganization of auditoryprocessingacross the sleep-wake cycle.

12/n .Finally, the identified processing characteristics also help understand why we lose consciousness when falling asleep, since it shows the dynamics of neural information changes differs between states.

Take homes:.-amplitude of ERPs, or they differences, is not a valid indicator of information processing in the brain.-co-I analyses yielded that especially redundant information extended over greater latencies during sleep compared to wakefulness.(cont)

10/n This change in stim processing is reflected in the loss of consciousness during sleep. In other words, the lower consciousness levels during sleep may be explained as informationally weaker and poor states regarding their external stimuli processing capabilities.

9/n So, using co-I analyses we show, that the deeper the NREM sleep, the more redundant the processing became, with REM sleep being similar to N1. Deeper sleep was associated with less differentiated processing: the brain simply processed “more of the same information”.

8/n (before discussion) if you want to understand better the implementation of the information theory framework for neural/cognition check this led by @canalesjohnson

7/n.We found that Mutual information decreases with sleep stage and co-information redundancy increases. While the amplitude differences in the ERPs tended to increase as a function of sleep depth (REM similar to N1), the effect sizes tend to decrease when computed with MI.

6/n .Then we found that temporal generalisation pattern generalise from N2 to N3 but not from awake to sleep stages, they don't tell us about the information flavour and hence lack interpretability.

5/n .We found a reliable local mismatch effect during wakefulness and all sleep stages (i.e., N1, N2, N3, REM) with the waveform substantially changing from wakefulness to sleep.

4/n .We here present the tone-pattern expectation violation to participants in wake and every sleep stage. If you want to know a bit more about the experiment from a circadian and physiological perspective, check the previous paper

This is a global-local study (Bekinschtein et al 2009) on sleep with true analyses of information processing. Check the pre-registration if you are geeky. or carry on reading. (
