When and How to Deviate From a Preregistration, with Prof Daniël Lakens Prof Daniël Lakens will share guidance on appropriate circumstances and methods for deviating from a pre-registration

When is it appropriate to deviate from a pre-registration, and how should this be done? 🧐

Join us to find out from Daniël Lakens @lakens.bsky.social at the next ReproducibiliTea!

Recurrence affects the geometry of visual representations across the ventral visual stream in the human brain The specific roles of feedforward and recurrent processing in human visual object recognition remain incompletely understood. In this neuroimaging and computational modelling study the authors isolate...

By utilizing the visual backward masking paradigm, this study aimed to disentangle the contributions of feedforward and recurrent processing, revealing that recurrent processing significantly shapes the object representations across the ventral visual stream.

What happens to the brain’s body map when a body-part is removed?

Scanning patients before and up to 5 yrs after arm amputation, we discovered the brain’s body map is strikingly preserved despite amputation

While many believe being ‘more in tune with your body’ improves mental health, we surprisingly found the opposite: worse mental health (higher anxiety, depression, stress, fatigue & reduced well-being)—with stronger stomach-brain connections.

6/11 One of our most striking (and unexpected) findings was that an individual child’s brain functional connectivity is more similar to their childhood peers than adults are to other adults. That is, children showed less inter-individual variability than adults.

Precision functional mapping reveals less inter-individual variability in the child vs. adult human brain Human brain organization shares a common underlying structure, though recent studies have shown that features of this organization also differ significantly across individual adults. Understanding the...

What a fantastic time at IMRF! 🎉

Huge thanks to the brilliant speakers for making our symposium on “Blindness as a Window into Brain Organisation” a big success! Big thanks to the organisers and the scientific community for this stellar event! Great to see so many friends and colleagues! #IMRF2025

Lénia Amaral presented her work at the ‪@imrf.bsky.social!

Her talk, “Stable, but unique: individualized connectivity in the blind V1 over time” reflects her postdoctoral work with @striemamit.bsky.social at the SAMP Lab, Georgetown University.
