Out in @CurrentBiology: a challenge to traditional views on distorted body representations. With @LukeMillerNeuro and @pmedendorp at @DondersInst we found that biases in hand perception stem from somatosensory computations, not a distorted hand model. authors.elsevier.com/a/1j2ki…

A challenge to the long-held idea of distorted hand model! With @LukeMillerNeuro & @pmedendorp we show that biases in finger perception arise from the Bayesian integration of accurate but noisy signals encoded in spatial coordinates. Preprint: bit.ly/46LOrSA

#Psychtoolbox 👀 gaze-contingent paradigms remap visual stimuli in real-time ⏱️ depending on gaze direction. New research uses this method to map visual receptive fields 🧠during natural free viewing. #eyetracking #visionscience #matlab doi.org/10.1038/s41467-023-3…

Detailed characterization of neural selectivity in free viewing primates

Paper alert! Many of us assume that when amputees feel a touch on their face, they also sense it in their missing hand, all thanks to brain plasticity. But what if this is based on flawed scientific evidence? Here’s a breakdown of our paper doi.org/10.1016/j.cortex.202…

Interesting results from some Twitter polls - academics believe that academia hires candidates with privilege even if they don't translate that into higher performance/outputs. Worth thinking about & potentially doing some more rigorous research.

== Academic hiring: gaps between WOULD versus SHOULD == Previous tweet blew up, and I personally learned a lot about academia from it, so here is a followup. I ran two surveys about hiring practices, how we hire versus how we should hire. Here's a comparison: 🧵👇

All NeuroImage and NeuroImage:Reports editors have resigned over the high publication fee, and are starting a new non-profit journal imaging-neuroscience.org This comes with great regret, and a huge amount of thought and discussion- please read announcement to get more details.

paper 131 my lab member ⁦@CeliFoster⁩ gives an overview over earlier-than-previously-thought interactions of processing visual faces and bodies. From there, she proposes a distributed model for their integrated processing. journals.sagepub.com/doi/10.…

A Distributed Model of Face and Body Integration - Celia Foster, 2022

Separated face- and body-responsive brain networks have been identified that show strong responses when observers view faces and bodies. It has been proposed th...

❗️Preprint Alert❗️ 🤘🍾🎉 We show that both localization-based perceptual hand maps and tactile distance perception on the hand change following a recalibration protocol that is based on visuotactile ventriloquism. biorxiv.org/content/10.1101/…

Modulation of implicitly perceived hand size by visuotactile recalibration

When concurrent visual and tactile stimuli are repeatedly presented with a spatial offset, even unisensory tactile stimuli are afterwards perceived with a spatial bias towards the previously presen...

Linux is available in many different distributions. We recommend Ubuntu as it is a beginner friendly distribution, tested with #Psychtoolbox, and if you install a Long Term Support (LTS) release you will get security updates for at least 5 years - great for long running studies!
