Wow, Pluto is incredible. Because of my python muscle-memory I've just been running julia in jupyter whenever I needed a notebook but I finally took the plunge and it's crazy how many features this thing has. #julialang

“New horizons for Julia”:
My article about #Julialang and new directions for the language. I talk about new tooling for installation, compilation to small binaries, and more. Julia is simply the best and most fun language for #science and #engineering.

Thrilled that my paper is out in the @nature.com. We explored how the brain builds complex tasks by compositionally combining simpler sub-task representations. The brain flexibly performs multiple tasks by dynamically reusing neural subspaces for sensory inputs and motor actions

We compared the TRACKPixx3 eye-tracker against the EyeLink 1000 Plus. Across 8 tasks, accuracy was similar. One key difference: TPx3 aggressively smooths sample data, which may affect sub-fixation phenomena and fixation onsets. Check the paper for the full results.

the cutoff scores for #MSCA postdoc fellowships are very high this year. has the score distribution shifted compared to previous years? I made a plot with scores from past years.
if scores are at ceiling level, the process becomes essentially a lottery, because minor issues can lead to deductions.

There is growing interest in how cognitive control may improve value-based decision making.
However, we find that a recent paper overestimated the role of control in their task, leading to erroneous interpretations of dACC recordings.

🧠 Summary:
We study calibration-free BCI using ERP data and show that rCCA, originally from c-VEP, performs very well when transferred to ERP, being on par with the SOTA UMM. Both reach very high accuracy without any supervised training.
