Dear Gert Jan, great talk, I fully agree with you that the function of Hypocretin in wake is crucial and we need to understand their exact functions looking at their activity during behaviors, their inputs and outputs. What you believe is the main function of Hypocretin neurons? Pierre-Hervé LuppiPosted onOctober 6, 2023 9:56 am

Inspiring lecture. Is there any data on influence of levels of hypocretine on cataplexy? Why some patients have typical and other atypical cataplexy? How are other wake-promoting neuromediators and systems involved in the disease development? Posted onOctober 6, 2023 9:55 am

Nice speech. But what does evolution theory have to do with science here? the similarities with animals that are found may also indicate the same Creator. I know this is a belief, but evolution is also unproven and therefore also a belief. I'm really a bit disappointed that this is being used here as if it were science.

For Dr Lavigne. Thaks for your nice presentation. In order to advance in the knowledge of the interaction between bruxism and AOS, dont you think it would be necessary to use more sophisticated diagnostic tools than EMG recording devices?Posted onOctober 5, 2023 4:51 pm

Hellow my name is Katerina Vlami from Athens Greece I have a question for prof. Lavigne. Can we use sleep bruxism as a biomarker (asking patient for Bruxism) in OSA management since bruxism might be a compensatory effect protecting from sleep apnea? and what about cardiovascular disease can it be used as an index of decreased cardiovascular morbidity since those who have sleep Bruxism share some common genes with those with sleep apnea So those who have simultaneously bruxism and sleep apnea may not be prone to cardiovascular disease ? Thank you very much for your excellent presentation!Posted onOctober 5, 2023 4:51 pm

Marian Martinez , Spain: thank you for thenice presentation. Dra Carra, can we think about the possibility of consider that bruxism in AOS children could constitute a different AOS phenotipe?Posted onOctober 5, 2023 4:28 pm

Do we really want to screen patients with minimally symptomatic (likely mild OSA)? They will unlikely tolerate CPAP treatment, but may pose a burden on the waiting list of already busy service. Posted onOctober 5, 2023 4:13 pm

Thank you very much for your brilliant presentation, Yon. The arousal identification, of course, is necessary for endotyping, but when you are going with HSAT, the recent reports, we know that arousal burden did not correlate with identifying CVS mortality risk contrary to ventilatory and hypoxic burdens.

Christopher McCausland, Ulster University, Northern Ireland. A brilliant presentation, thank you. A question for Jon, what are your thoughts on explainability or interpretability within sleep AI; are the algorithms accepted clinically or still viewed with some suspicion? Posted onOctober 5, 2023 11:49 am

Marian Martínez from Spain. The enormous OSA infradiagnosis leads us to use simple diagnosis methods but the new concept of individual and precision medicine needs more sophisticated algorithms. Scoring arousals is very important. How could we conjugate both concepts?. Maybe AI is the key?Posted onOctober 5, 2023 11:36 am

Thanking Dr Susana for the extraordinary presentation, I wanted to ask what is the way forward? Simplification to increase diagnosis or an extensive characterization of phenotypes with characterization of sleep quality? What do we really need?Posted onOctober 5, 2023 11:27 am

This excellent Kahoot and high disagreement shows us how much standardization is still needed in my opinion. I also always wonder about the validity of our likely arbitrary rules for switching between sleep stages every 30 seconds and what determines how that is done when I see the complexity of the rules (Erna Sif Arnardottir, Iceland)Posted onOctober 4, 2023 4:15 pm

Is valid to study de Glymphatic System in Humans by MRI despite being awake? should be using anesthesia? Is valid the results in awakes patients? Posted onOctober 4, 2023 1:12 pm

Short follow-up: if i recall correctly, during fixation processes the PVS is (partly) collapsed, which could explain that tracer entrance into the brain parenchyma could happen post-mortem, right? Posted onOctober 4, 2023 1:11 pm

Since anesthesia does the same, is this sleep function or just a correlate of reduced activity?Posted onOctober 4, 2023 1:09 pm

Atrial fibrillation is characterized by irregular heart beat: How might this influence the flow in the perivascular space, and glymphatic clearance of metabolites? And what about coronary heart disease - or small vessel atherosclerosis in general - would this decrease or increase pulsatility of the perforants from the pial vessel, and how would this reasonably affect glympatic function?

What is happening to the glymphatic system during REM sleep? Posted onOctober 4, 2023 1:05 pm

Pierre-Hugues Prouvot (Switzerland): Thank you I learned a lot with that talk. Do you think REM sleep is specifically important in this flushing mechanism owing to the increase in bloodflow and vasodilation during that period? So REM sleep perturbation during AD or PD could worsen the situation even further. Posted onOctober 4, 2023 1:04 pm

Giulia Zerbini, University of Augsburg (Germany) Question for Valentina Elce: Many thanks for the interesting talk. You mentioned that sleep onset and offset are predictors of dream recall frequency. Could you tell us more about this relationship? Are for example later or earlier sleep times related to a higher frequency of dream recall?Posted onOctober 4, 2023 10:14 am

Laurent Sheybani (London, UK and Geneva, Switzerland) - Have you find some sort of "entrainment"? That is, increased DE across the 14 days? Or a change in dream content across the experimental timeline? Posted onOctober 4, 2023 9:56 am

Laurent Sheybani (London, UK and Geneva, Switzerland) - The LC seemed to be asymmetrically activated or did I misinterpreted the figure? Thank for the presentation!Posted onOctober 4, 2023 9:49 am

Very interesting talk. I am also interested in sleep and memory consolidation and the use of closed-loop TMR in older adults and people with Parkinson's disease. How can we know for sure that with the auditory stimuli we are actually reactivating specific memories and not increasing the coupling in a non-specific manner? Letizia Micca, KU Leuven, BelgiumPosted onOctober 4, 2023 8:01 am

Thank you for presenting your amazing work. Question on the iEEG coupling study: The fact that these were epileptic patients, how did that impact results? E.g. the non-coupling nights, were there more nocturnal seizures that might impact memory consolidation as well? Denise Bijlenga, The Netherlands. Posted onOctober 4, 2023 7:58 am

Could the increase in delta activity during sleep after exposure to blue light be a compensatory reaction rather than direct consequence? In other word isn't it too brisk to say that blue light infamy is to be discarded, based on the present unclear cause-and-effect relationship?Posted onOctober 4, 2023 7:24 am

Peter Meerlo, Netherlands: You showed increased in EEG deltapower during sleep with increased light intensity during the day, perhaps suggesting that light affects the build-up of sleep need/pressure.
