How does the perception of our bodily self arise in our experience, and to what extent do we process body ownership information unconsciously? In a new study (preprint), we found body ownership information processing cannot occur without awareness. 0/14👇 doi.org/10.31234/osf...

So it is fitting that in 2008 she was awarded the Rosalind Franklin medal by the Royal Society. #neuroscience #psychology

There’s now a direct daytime train between them, that takes 8 hours and costs just €59. Leave at 10am, arrive 6pm.
And… it’s just 1% the carbon emissions of the equivalent flight

I don't think so, I feel we know little to extrapolate this type of decision back to animal models... but worth a discussion

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.
11/n
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”.

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