Such a pleasure to see the first results by @ege-kingir.bsky.social, stemming from a wonderful collaboration between Dept Neurology @mpicbs.bsky.social & #MelanieWilke ‘s lab @uni-goettingen.de ! 💫

Thank you very much for your kind words @michaelgaebler.com !
It was a great pleasure to be able to give back to the annual #MindBrainBody symposium which gave me one of the most special moments of my PhD career last year 😌🥂
We reveal this by a novel method to estimate trial-averaged respiratory HRV (traditionally known as RSA) and respiratory phase-INdependent heart rate modulations simultaneously 📏
We show that these two components of ACD might differentially relate to visual perception 👀🧠 [2/2]
Our latest work on respiratory and non-respiratory contributions to the Anticipatory Cardiac Deceleration (ACD) is out! 🫁🫀
As suspected, respiration accounts significantly to the ACD via respiratory HRV, but it seems that it does not fully explain it! [1/2]
onlinelibrary.wiley.com/doi/10.1111/...
an interesting perspective to show that respiratory phase alignment is not just coincidental or due to the "rhythm" of repeated trials
Thank you very much! 😊
🚨 We’re running a short self-report study on how BREATHING interacts with your daily life 🫁🌍
We're struggling to find participants and would truly appreciate your help; it only takes a few minutes.

🙏 Feel free to share the link with others. Thank you!
Let me also do a round of hashtags to reach a few visual consciousness researchers that might be interested in our publication:

🎊 Final version is finally out on Consciousness and Cognition as open-access 🎊
doi.org/10.1016/j.co...
As a lucky coincidence, this means I also get to celebrate my birthday with the first publication of my PhD 🙂
Thank you for the initiative, I'd love to be added as well! I'm a PhD student working on the interaction between interoceptive signals and sensory perception :)
Thanks a lot! 🧠🫀
Thank you very much!!
I'm extremely honoured to receive the Young Scientist Award at the MindBrainBody Symposium this year! 🎊
Big thanks to @mpicbs.bsky.social and everyone involved in the organization!!
Already looking forward to share results from my upcoming experiments in the next edition of #MBBS

Our preprint provides an analysis framework to separate internally generated switches in conscious content, from those that are induced exogenously.
Such categorization is valuable to understand how our brains update conscious content, without AND under exogenous influence.
[7/9]
Finally, we estimated that 24.4% of all perceptual switch events in Task 1 are induced by saccades, hence not spontaneous.
[6/9]
Comparing PSLs from our implementation of Hesse & Tsao's paradigm (Task 1) against the continuous binocular rivalry task wherein both external factors are absent (Task 2), we estimated time windows that we can exclude if we want to discard "induced" switches.
[5/9]
If the FPs jump at t=0 but the subject only fixates to the center (Task 3); there is a small change in perceptual switch latency (PSL) distributions.
If the subject performs saccades while FPs remain stable (Task 4), distribution changes a lot.
Saccades induce time-locked switches!
[4/9]
We implemented a two-factorial design to test the influence of the two external factors ("visual appearance of the new fixation points" and "requirement for a saccade to follow them") on the timing of perceptual switches.
[3/9]
But can we use it to study the internally generated transitions between different conscious contents?
The task requires "jumping fixation points" and "subsequent saccades to follow them". This made us wonder if some perceptual transitions (switches) are induced by these factors.
Figure 2 from Hesse & Tsao (2020): https://doi.org/10.7554/eLife.58360
[2/9]
In this elegant paradigm; each rivaling stimulus has its own fixation point (FP) that "jumps" every few seconds, and subjects follow the FP of the perceived object with their eyes.
The paradigm is utilized to show how the conscious and subconscious content is encoded together in macaque IT.
📰 New Pre-Print 📰
[1/9]
There is an increasing interest to study spontaneous transitions in the contents of visual consciousness.
Here, we test the suitability of a novel no-report binocular rivalry paradigm, originally developed by Hesse & Tsao (2020), to study such transitions.
