ReproNim 'First Fridays' Webinar – Friday, October 4, at 2pm Eastern Time

Our special guest speaker this month is Mike Milham<https://childmind.org/bio/michael-p-milham-md-phd/>, who joins us from the Child Mind Institute, for a presentation on some of his very recent work (Nature Human Behavior, August 2024<https://www.nature.com/articles/s41562-024-01942-4>): "Moving beyond processing- and analysis-related variation in resting-state functional brain imaging." [See Abstract below]

Mike’s work spans brain development, child and adolescent psychiatry, and the advancement of neuroimaging data sharing initiatives and implementation of big data all in the service of understanding how functional & structural connectivity in brain may underlie mental illness. Among numerous leadership positions, he is the founding Director for the CMI Center for the Developing Brain, and Director of the Healthy Brain Network. He has pioneered innovative initiatives, including co-founding the 1000 Functional Connectomes Project, and that project’s International Neuroimaging Data-Sharing Initiative.

Abstract
When fields lack consensus standard methods and accessible ground truths, reproducibility can be more of an ideal than a reality. Such has been the case for functional neuroimaging, where there exists a sprawling space of tools and processing pipelines. We provide a critical evaluation of the impact of differences across five independently developed minimal preprocessing pipelines for functional magnetic resonance imaging. We show that, even when handling identical data, interpipeline agreement was only moderate, critically shedding light on a factor that limits cross-study reproducibility. We show that low interpipeline agreement can go unrecognized until the reliability of the underlying data is high, which is increasingly the case as the field progresses. Crucially we show that, when interpipeline agreement is compromised, so too is the consistency of insights from brain-wide association studies. We highlight the importance of comparing analytic configurations, because both widely discussed and commonly overlooked decisions can lead to marked variation.
