Neurosalience

Welcome back to Neurosalience! In this episode Peter Bandettini talks to production lead, Dr Rachael Stickland. They discuss the best bits and themes from season 1 and what to expect from season 2. 

This episode focuses on layer activity fMRI, an important and rapidly emerging area of neuroimaging research. Layer fMRI opens up the possibility of mapping directional communication channels between active brain regions. Peter discusses the challenges, limits and opportunities of ultra-high resolution fMRI with four leaders in this research field - Rainer Goebel, David Feinberg, Jon Polimeni &amp...

In this podcast, Peter talks to Dr. David Poeppel, a Professor of Psychology and Neural Science at New York University (NYU). Peter and David discuss how MRI and other imaging modalities may play a part in truly understanding the brain as well as what it even means to understand the brain. They discuss David’s past work with Greg Hickok on language pathways, and his work in the auditory cortex. An...

Michael Breakspear, Ph. D. is a physicist and psychiatrist and the leader of the Systems Neuroscience and Translational Neuroimaging Group at the Hunter Medical Research Institute at the University of Newcastle in Australia. In this wide ranging discussion, Peter talks to Michael about his motivations for dynamic modeling of the brain and how his research may pay off in the long run towards clinic...

Dr. Ahmad Hariri is Professor of Psychology & Neuroscience at Duke University, where he is also the Director of the Laboratory of NeuroGenetics. Dr. Hariri recently published an important paper on the test-retest reliability of common task-fMRI measures. This received attention in the field and from the popular media and generated useful discussions. In this podcast Peter and Ahmad discus...

This podcast idea was precipitated by Dimitri Kullman’s 2020 editorial in Brain , causing a stir in the community. It levelled criticism about the clinical validity of fMRI. Some of it was outdated but some was indeed on point.  In this podcast we had a great discussion on all things fMRI -  what it can and cannot measure, and how it can continue to proceed. We also discuss some of the s...

Here Peter Bandettini has a wide  ranging discussion with the 2021 Early Career Investigator Awardee, Chao-Gan Yan. They talk a bit about his career path, the highly impactful work he has been doing, as well as some of the most challenging issues in fMRI: dealing with motion, variability, finding biomarkers, and designing just the right packages that help the beginner and  expert alike. Chao-Gan g...

In this week's episode, Peter discusses the history of the Open Science Special Interest Group and the unique and important role this group plays in OHBM, alongside Janine Bijsterbosh, Johanna Bayer, Katie Bottenhorn, Melvin Selim Atay and Aki Nikolaidis. The OHBM Open Science Special Interest Group fosters open science not only by encouraging best practices and sharing data and code, but by encou...

Join host Peter Bandettini as he talks with Dr. Nikolaus Weiskopf, Director of the Department of Neurophysics at the Max Planck Institute for Human Cognitive and Brain Sciences.

In this episode of NeuroSalience, Peter chats with Alex about connectomics, or the study of the brain’s networks of connections. We discuss Alex’s work leveraging the Allen Brain Atlas (https://portal.brain-map.org/) and fMRI to better understand the genetic basis of the network structure. He points out clear differences between network hubs and other network components, with hubs having important...

In this episode, Peter Bandettini meets with Tom Nichols, Remi Gau and Jack Van Horn to discuss the motivation for a set of best reporting and analysis practices. This provides insight into how the COBIDAS (Committee on Best Practice in Data Analysis and Sharing) in OHBM was started. They talk about the reproducibility crisis in fMRI and how it is being addressed. They discuss how the culture of f...

In this episode Peter Bandettini meets Carolina Makowski, Michele Veldsman and Alex Fornito to discuss the OHBM Student–Postdoc special interest group (SIG) , with particular emphasis on their mentoring scheme and meeting-related workshops. Carolina is a current member of the SIG and Michele previously served as its Chair, Alex has been an active mentor to several junior OHBM members over the year...

In this conversation, Peter Bandettini meets members of the BrainArt SIG to discuss its history from the NeuroBureau to its current formal SIG status. They discuss what brain art (or more generally science art) is, consider what the best features of brain art are and how, essentially, any scientist trying to convey the essence of their findings can be considered an artist. You’ll discover the plan...

In this conversation, we cover the history of the Brain Art SIG through the time when it was run by the Neuro Bureau. We discuss what brain art or more generally science art is, as well as go into some of the thoughts on what the best features of brain art are, and how essentially, any scientist trying to convey the essence of their findings, is an artist. We go on to discuss some of the competiti...

This week’s podcast is centered on physiologic fMRI. Generally, when people think of fMRI, they think of a way to map neuronal function, however there is so much information about neurovascular physiology in the signal. Many researchers who use fMRI may not realize all of the potentially untapped information—and confounds!—in the fMRI time series. Dr Jean Chen and Dr Molly Bright each run research...

In this week’s podcast, you’ll hear about clinical applications of resting-state fMRI from Dr Michael Fox. You’ll hear some of the highlights of his research, from the beginnings at Wash U, including his early work on resting-state fMRI and the issue of global signal regression, to his more recent pioneering work on lesion network mapping. Through this, you’ll find out about how lesions can impact...

Peter Bandetti talks to Catie Chang, who walks us through her thought process regarding pulling information out of the fMRI time series. After discussing some of the ongoing issues in fMRI, such as whether or not to use global signal regression to remove noise, she leads us into a commonly overlooked effect in fMRI—that of changes in arousal and vigilance. In particular, this has measurable effect...

In this week's episode, Peter Bandettini talks to directly to MRI scanner vendors. Together, they try to reconcile the importance of fMRI in research contexts with the market pressures of developing clinical applications. As fMRI has virtually no clinical market, does it really influence vendor decisions on pulse sequences and hardware? Could more be done aside from making fMRI more clinically...

For our third episode, we bring you a birds-eye view of modeling messy biologic systems, namely the brain. Peter Bandettini talks to Danielle Bassett about the challenges of measurement accuracy and what scale might be most informative for modeling, including how to make do with what we have. From the clinical perspective, they talk about network control theory for modulating networks for therapy...

Peter Bandettini introduces Aperture, a new open access publishing platform for neuroimaging research that he co-founded with Jean-Baptiste Poline. Joining them both are the new Aperture Editor In Chief, Tonya White and the journal manager, Kay Vanda. Together, they discuss the motive, history, steps for creation, and current status of Aperture. It was created with the strong support of the Organi...

Peter Bandettini chats with Rachael Stickland, where they set out some of the exciting conversations you’ll hear on OHBM Neurosalience. The name ‘Neurosalience’ highlights the aim of this podcast - to put a spotlight on important developments, discoveries and controversies in the world of human brain mapping. Find out why this podcast was set up, what the main themes and topics will be, and what t...
