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.

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.

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. Different from an earlier one from Strauss et al www.pnas.org/doi/10.1073/... where there was little MMN in MEG.

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 pubmed.ncbi.nlm.nih.gov/35998110/

This is a global-local study (Bekinschtein et al 2009 pubmed.ncbi.nlm.nih.gov/19164526/ on sleep with true analyses of information processing. Check the pre-registration if you are geeky. or carry on reading... osf.io/m23eh/?view_...

First, let us see the poses of the serious people involved in this work, including one of mine... because why not!?

How does information processing during sleep really change?

Brain activity might be higher but brain information is lower and redundant.

Great and early discussions with Christine Blume and wonderful work from @Andrés Canales-Johnson conceptual and methodological analysis.

14/15 CRPS and other chronic pain conditions are highly variable, and we need the development of personalized methods if we want to better define the relationship between neural and experience data in chronic pain, as well as develop new therapeutic avenues. (Heather Sarit)

13/15 Using long-term phenomenal and neurophysiological measurements in an ecological setting we attain single participant power. This new method to investigate chronic pain better samples phenomenal experience with a pseudo-continuous measure, overriding one-time Likert scales

12/15 The "other" limb pain traces neurally mapped to alpha and theta, while when attending to the pain-limb or other aspects of the body the neural process may be more complex, probably mapping into brain communication, complexity or network measures. (from John Washinton)

10/15 pain intensity increases attending to painful limb, and decreases when the other limb is attended. Importantly, our results provide proof-of-principle that attention might induce pain relief when the focus is on one’s own breathing or heartbeat.

9/15 Interestingly, alpha and theta power correlate with the traces of pain when the focus is on the non-affected limb, but not when attention focuses on the painful limb. This suggests that neural processing depends on the focus of attentions!
November 7, 2023 at 9:35 PM
8/15 we also saw neural differences in brain spectral power between conditions, point to the possible neural info to define the focus and its relation to pain.
November 7, 2023 at 9:33 PM
7/15 further showing the strength of the Method we did a series of correlations to see the relationship between pain traces each day and some of the other relevant dimensions of experience. We separated them by focus of attentions time sections.

6/15 The power of Temporal Experience Traces (over any other version of reports) reveals that we can see single participant statistical differences and evolution through our the 3 weeks, between the focus to pain, to other limb, heart or breathing.

5/15 The Chronic Regional Pain Syndrome Patient traced his experiences during the 4 focus of attention conditions 20 times in 20 days while wearing the portable EEG at home.

I went this morning to the Isaac Newton Pub to see the #fifawwc with a couple of friends. The geeky + football vibes and the combination of coffes and teas on the tables with morning beers was an odd sight, in line with a non-male majority patrons.
Congrats to las soñadoras for achieving the dream.
