Anyone got a spare tachistoscope?

I quite like the hypothesis that 'mental fatigue' may be due to impaired ability (possibly genetic) of atrocytes to clear (uptake) glutamate leading to impaired information processing and increased extracellular glutamate. This could explain sensory sensitivites, reduced ability to distinguish...

Many thanks!

Thanks @MeSci for the links which led me to this study (the same researcher from the above ME/CFS study) that I don't think I've come across and is exactly the sort of thing I had in mind in mentioning psychologists (who ted to get a bad rap here but it's a very diverse field). Restricted...

That looks to me very much like the 'coma' you get in astronomical telescopes due to spherical aberrations off axis (easy for me to say :)) : https://en.wikipedia.org/wiki/Coma_(optics) Perhaps some distortion in the curvature of the cornea? PS - I also get the snow effect - when looking at...

Two points. I noticed references to these tests being used in respect to brain injury and I have a particular interest in post-concussion syndrome. Secondly I wonder is there a way of disagregating deficits due to ocular muscle fatigue from neural deficits?

I agree. There are some old school techniques I remember from my Psych undergrad days that might be very enlightening.

Not from the same study unfortunately but these recent findings of visual deficits due to sleep deprivation : https://www.physoc.org/news_article/biomarker-to-avoid-safety-risk-for-the-sleep-deprived-eye-movement-test-indicates-sleep-loss/ strike me as similar, on first reading, to those...

I was probably a little cryptic in referring in non-specific terms to 'the narrative' in respect to the Graun's reporting of ME/CFS. I suspect it has something to do with SMC/the BPS crowd/the BPS influenced NICE guidelines being accepted as the 'experts' whereas some vocal and newsworthy...

Possibly because all Guardian output begins and ends with 'the narrative'.

To be fair, they do address the issue of fluctuating symptoms to an extent :

I'm just starting to read through the full text but one observation that concerns me immediately is the weight given in the hypothesis to 'its long history epidemics, outbreaks or clusters' (sic) and how this informs the notion that any genetic predisposition must be common. I am yet to be...

In the domain of thermoelectric materials only for the time being but this machine learning program was able to 'predict' later findings from older papers : https://www.zerohedge.com/news/2019-07-10/ai-pores-over-old-scientific-papers-makes-discoveries-missed-humans But in principle the...

Highly selected to exclude conditions which may be directly biologically relevant?

Summary from the full paper if anyone is interested (my para breaks and bolding): https://www.biorxiv.org/content/biorxiv/early/2019/01/26/528117.full.pdf

I agree with the suggestion that there are problems with often arbitrary diagnostic categories based on often overlapping symptoms. Sod all to do with 'trauma' though : https://www.biorxiv.org/content/10.1101/528117v1

Anecdotally (and acknowledging that sex hormones may be acomplete red herring or hormone levels may be affected by ME/CFS rather than the other way round) my testosterone levels dropped at age 34 to below normal range co-incidentally with a severe and permanent downturn in my health. Given that...
