2022-12-081h 42OHBM NeurosalienceNeurosalience #S3E6 with Michal Ramot - Changing your brain with real-time fMRI neurofeedbackReal-time neurofeedback fMRI is a unique and powerful kind of fMRI involving real time feedback of brain activity to the subject towards the goal of enhancing or suppressing activity or connectivity, and ultimately changing behavior. Michal’s work has taken real time neurofeedback fMRI to the next level, embracing operant conditioning to alter measured fMRI network activity independent of the subject’s awareness or conscious control. Here Peter and Michal discuss all the types of neurofeedback-based fMRI, focusing mostly on her implicit neurofeedback studies.

2022-10-121h 24OHBM NeurosalienceNeurosalience #S3E2 with Prantik Kundu and Charles Lynch - Multi-echo EPI: An under-utilised tool for fMRIThis week on #Neurosalience, we discuss one very cool and very useful fMRI acquisition strategy called Multi-echo EPI. While it’s been around for over 20 years, only a fraction of papers reporting fMRI results have used it. It can help quite a bit towards increasing sensitivity, mitigating signal dropout and motion artifacts, and stabilizing the time series to allow for tracking of very slow changes. Recent papers have come out showing that it significantly helps increase sensitivity and mitigate artifacts. In fact, several prominent leaders in the field are embracing it as they are convinced it's essential for increasing th...

2022-01-101h 17OHBM NeurosalienceNeurosalience #S2E13 with K. Kwong, R. Turner, and R. Menon - A deep history of fMRIFunctional MRI is a profoundly successful and powerful technique that so many of us use. It’s still developing and adding to our insight about the human brain. While MRI was developed in the late 1970’s and early 80’s, it would be another decade before it was realized that MRI could be used to detect and map, non-invasively, human brain activation. My guests today, Ken Kwong, Bob Turner, and Ravi Menon were the first who showed this capability. Ken’s successful experiment in early May of 1991 was arguably the first. Ravi, who was the key player in the Minnesota group, h...

2021-04-3054 minOHBM NeurosalienceNeurosalience #S1E7 with Jean Chen, and Molly Bright - The opportunities and challenges of physiologic fMRIThis 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 groups that focus on this information in complementary ways. Both use physiologic manipulations and an array of acquisition methods to probe and characterize details of the hemodynamic response, though their two research progra...

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 behavior through their effects on functional networks. This approach is a promising inroad of fMRI towards clinical utility.

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 effects on the resting state fMRI signal. She discusses the perspective that one person’s artifact may be another’s useful signal, depending on the goal of the study.
2021-03-2649 minOHBM NeurosalienceNeurosalience #S1E4 - The unique relationship between scanner vendors and the field of fMRIIn 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 relevant? In this discussion, you’ll hear some fascinating history into the early days of echo planar imaging and high speed imaging, as well as insight into the processes by which products are prioritised. You’ll also find out...

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 and discuss limitations in technology. They also talk about the limits of network modeling and the search for the equivalent of an idea as powerful as “natural selection” for the brain. In the second part of the...

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 Organization for Human Brain Mapping, and aims to be a peer-reviewed platform for publishing papers, but also various other types of research objects that do often not find space in conventional journals, including data, educational tutorials and code. While...
