ESMRMB Reproducibility Highlights

From lab to life: in vitro and pre-clinical MRI with transparency (13:00-14:30 UTC)

Henning M. Reimann: Novel Ways of Science Communication and Collaboration: OpenMinds – Enabling the 3Rs for Animal Welfare by Promoting the 3Rs for Scientific Value

Rodent functional magnetic resonance imaging (fMRI) can replace more invasive readouts for assessing brain activity. However, the necessity to anesthetize animals during examination has a prominent impact on study outcome and comparability with human studies. Anesthesia affects overall physiology, including brain states, functional networks, information transfer, sensory processing and hemodynamic integrity—i.e., the physiological translation of neuronal activity into hemodynamic responses captured by fMRI. Thereby, different anesthetics affect the above measures in distinct ways, which pose a further challenge for data interpretation. With “OpenMinds” we proposed an open encyclopedia for anesthetic effects as platform to report and share findings and data with the mouse fMRI community. The goal is to provide a powerful web-based infrastructure for fast and easy dissemination of findings, data, and protocols to gain a better understanding of anesthetic effects. The initial goal was to establish optimized anesthetic protocols and define robust experimental conditions for functional neuroimaging studies, and in turn foster scientific quality and reduce animal numbers. Now we are taking OpenMinds to a new level by expanding the framework both in terms of content and functionality to create a tool for novel ways of science communication and collaboration.

Joanes Grandjean: Animal Imagers Unite! Lessons learnt from working together and path forward

How to best acquire rodent preclinical functional MRI data? Every laboratory has an opinion on this, but are they truly objective? It has become apparent that we work with different data quality, with different potentials to capture functional connectivity phenomena, and these discrepancies cannot only be linked to preprocessing differences and analysis schemes. I describe our community effort to describe dataset performance, identify potential best practices, and test them out in laboratory conditions

Shella Keilholz: Moving Towards Open and Accessible Scientific Publishing

Science relies on the dissemination of research results. Traditional publishing models block this content behind paywalls, whereas open access models allow content to be reached freely. However, in many cases, open access publishing simply shifts the financial burden from the reader to the author. The potential and challenges of open and accessible scientific publishing will be discussed in the context of the recent editorial resignation from NeuroImage and the founding of the non-profit journal Imaging Neuroscience.

Agah Karakuzu: Are zombie code and mummified data haunting your PDFs? Resurrect your publications with Neurolibre Living Preprints

Francesco Santini: MRI Together and the ESMRMB: synergy and opportunity

MRI Together was born in 2021 out of the desire of passionate researchers to create a virtual, inclusive place, to connect with likeminded people and discuss and share the topics of open, reproducible, and inclusive science. We wanted it to be a self-organized event, with a slightly crazy schedule. We thus approached the ESMRMB to receive technical and logistical support, and this was the beginning of a beautiful partnership. Since then, MRI Together has become an integral part of the ESMRMB itself, while maintaining its creative and organizational independence. Follow me in this talk about the history and the hopes for MRI Together.
