Was that a mosquito? 🦟🦟🦟 Well, you better consider the probability of mozzies in your current environment! Go check out my PhD project finally summarized in a preprint: https://t.co/7mbDTVKvus

Have you ever thought of why our human brain recognizes virtual faces as not being real🤖? Could the brain's responses vary when encountering the REAL and FAKE faces? Check our new preprint from the #Neurohum project:

Artificially created human faces play an increasingly important role in our digital world. However, the so-called uncanny valley effect may cause people to perceive highly, yet not perfectly human-...

Wow, what an incredible and unforgettable week! #LINO23 was truly inspiring and I am grateful for amazing exchanges with great nobel laureates and fellow young researchers from all over the world. I really learned a lot. Thank you so much @lindaunobel, @maxplanckpress & @MPI_CBS
It was beautiful! The Lindau Nobel Laureate Meeting ended today. All Max Planck participants - young scientists as well as Nobel laureates - thank you for the hospitality and the lively exchange. @lindaunobel #LINO23

Out Now 👉 How critical is brain criticality? 💥Does the brain operate near a critical phase transition? 💥And why should we care ? Check out (+share) our review in TINS @TrendsNeuro, hot out of the oven! Free access link: https://t.co/K8CarES5ve + more in the 🧵 below!

Our new preprint “Cardiac Activity Impacts Cortical Motor Excitability” is now out. In this work, we found that cardiac cycle 🫀 regulates motor activity 👋 through changes in cortical excitability. > https://t.co/apTp08rfhK ⬇️Thread

Great news: My final PhD paper has been accepted for publication in #JNeurosci @SfNJournals. 🥳 We show that respiration phase-locking 🫁 to expected stimulus onsets 🖐⚡️ corresponds to highest heart rate 🫀 (and presumably cortical excitability). ➡️ https://t.co/wnZZxuBUZ1

Do you plan to use #fooof to calc oscillatory #EEG power or to estimate the 1/f exponent? Avoid 3 common errors by checking this preprint! https://t.co/S5piYcKSAc

Hello @AcademicEEG people! If you are interested in studying the connectivity patterns with electrophysiology, please consider using HARMONI in your pipeline. It is the first signal-processing tool for suppressing spurious, harmonic-driven synchronizations. (1/4)

Many thanks to the author team, @HodappAlice, @IdajiMina, @arnovillri, and Vadim Nikulin – as well as to our reviewers, @_rdgao and @nweisz2, for taking the time to provide excellent and truly constructive feedback during the open peer review process. Comments/questions welcome!

Finally out in @eLife: We find that fluctuations of neural excitability, associated with pre-stimulus alpha oscillations, shape somatosensory intensity perception via initial cortical responses - yet with counter-intuitive modulations of evoked potentials. https://t.co/dyI7apcWJL

Excited to share that work w. U. Lindenberger and @Garrett_Neuro is now out in @NatureComms! 📢📖 Using EEG and fMRI we show that cortical excitability modulation involving the thalamus supports the processing of complex information under uncertainty. 🧠 https://t.co/fJJKWM21yq
