I’ve officially resigned as Associate Editor for Frontiers in Systems Neuroscience. It used to be a reputable journal, but became a case study in how forced automation destroys academic integrity. 👇
Raphael is presenting his poster in session 2 (P2-F-168): Practice makes precision: Motor execution improvements in a 2-D racing task are retained and generalized but depend on movement direction.

Elysa Eliopulos presents her poster (P1-F-142) today and tomorrow: "Redefining Explicit Motor Adaptation into Three Phenotypes" We find 3 ways in which people develop a strategy to counter a visuomotor rotation, _and_ that the mix of strategies depends on rotation size.

Today and tomorrow at #NCM2026 Jacob will be presenting his poster "Learning to throw against the current: internal models of object-environment dynamics" (P1-F-150). How do people learn to account for a sideways current, when launching a ball to a target? VR and 2D solution spaces...

Elysa will be presenting this work at #NCM2026 soon, so we thought to put up a first pre-print, a bit earlier than usual. previously we noticed that explicit strategies do not develop gradually, but in discrete steps. Here we wanted to test if that depended on rotation size
Just had a paper accepted after 4 rounds of revisions and *10* reviewers!

A not so bold proposal for the future of scientific publishing

"Frame Effects Across Space and Time" is published: doi.org/10.1167/jov.... The effect: - extends a bit over space, - not time, - mostly depends on frame edge positions - doesn't decrease with experience Looks like vision uses references to localize objects in space.

Vibe coded a Shiny app for data preprocessing. Meant as a tool for undergrads doing projects in the lab. Computer literacy is low across the board, and with tools like these (and the LLMs to build them) there's no need to understand what you're doing.

How do precision of movement and proprioception influence motor control and adaptation? Several theories—such as the exploration-exploitation hypothesis—propose that variability plays a key role in mo...

New preprint out! (doi.org/10.64898/202...) We examined how EEG activity during movement preparation and error processing distinguishes learning and error processing between motor adaptation and de novo learning.
EEG Dynamics of Movement Preparation and Error Processing Distinguish Motor Adaptation From De Novo Learning
Previous research has distinguished behavioral mechanisms between motor adaptation and de novo learning. However, electroencephalography (EEG) markers dissociating them remain unclear. Here, participa...

Someone in my lab asked me to make a QR code, yet again. So I vibe-coded them a Shiny app, and now you could use it too: mthart.shinyapps.io/ShinyQR/ Vibe coding is fun, but I would not use it for data analysis. Source code: github.com/thartbm/Shin...

I think almost all scientific projects should be planned carefully. And I think an app can dramatically improve that. So I wrote an app for that (free for now, if you can fund this let me know). I tested it quite a bit (>8000 users in beta so far). try it: planyourscience.com
Preprint: Frame Effects Across Time and Space (FEAST): www.biorxiv.org/cgi/content/... In the frame effect people perceive a large horizontal separation between two horizontally aligned flashed probes when they are flashed within a left-right moving frame.
Frame Effects Across Space and Time
When two probes are flashed at different times within a moving frame they can be perceived as dramatically separated from each other even though they are at the same location in the display. This effe...

In this paper, Andrew King looked at tools as cues for dual adaptation. He used a VR task, where a ball had to be launched to a target with a 30 degree rotation.

In this paper we use a new approach from control theory (engineering), a "disturbance observer", to see if it can be applied to visuomotor adaptation. This "DO model" is doing reasonably well.

In this study @deniseyph.bsky.social and I take data from 4 previous studies, and their pilots, with N=270 to look into potential relationships between precision of reaching directions and proprioception and various other measures.
