After this we discuss a wide range of topics that his group has been working on - falling into the categories of either methods development or mind-body interactions. He has played a major role in many insightful studies that include those using simultaneous EEG and fMRI, and looking at neuromodulation, brain plasticity, subliminal stimulation and...

2022-12-081h 42NeurosalienceNeurosalience #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. They discuss the real time fMRI feedback setup as well as the potential applications - for u...

2022-10-121h 24NeurosalienceNeurosalience #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 17NeurosalienceNeurosalience #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 minNeurosalienceNeurosalience #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...
2021-04-161h 09NeurosalienceNeurosalience #S1E6 with Michael Fox - Identifying and modulating pathological networksIn 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 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.
