Second Virtual Layer-fMRI ‘Dinner’: Laminae in the brain; fMRI vs. electrophysiology

On Sept 28th 2020, the second virtual layer-fMRI event is scheduled.

This meeting is held as a succession of the first virtual dinner in May 2020: https://layerfmri.com/virtualevent1/

In this second event, it will be discussed how the research field can bridge the gap between layer-dependent activity measures that are obtained with fMRI and electrophysiology, respectively. Kamil Ugurbil will present the perspective of high resolution for human neuroscience, Lucia Melloni will present the perspective of depth-dependent electrophysiological recordings in humans, and Seong-Gi Kim will talk about the combination of both worlds, layer-fMRI and layer-dependent electrophysiological recordings. 

Below you find the important links of the the virtual event. Embedded videos of the talks, discussions, and a summary of the hot topics are going to be added on the day after the event.

  • The meeting is organized and moderated by Luca Vizioli and Renzo Huber. This event is supported by CMRR (Essa Yacoub and Kamil Ugurbil) as well as the Maastricht-York partnership grant (PIs: Aneurin Kennerley and Renzo Huber).
  • This link will forward the attendees to the zoom link: https://layerfmri.page.link/meeting_channel.
  • The event will consist of three 20-30 min talks and a subsequent joint discussion.
  • The duration of the event will be approximately 90 minutes.
  • The event it open to everyone (there might be a limit of 200 simultaneous attendees).

Title: Laminar-resolution fMRI in animal models:  Signal sources and Implications for human fMRI

Abstract: Mapping laminar activity is of great interest in human fMRI community due to increased availability of ultrahigh field MRI and a necessity to move toward to systems-level circuit mapping.  Recently, many laminar fMRI papers in humans have been published at high profile journals.  However, many unsettled questions arise such as whether the fMRI signals are closely related to neural activities at a level of layers, whether the spatial hemodynamic response is close to the neural spread, etc.  My lab has been working on understanding underlying vascular sources of laminar fMRI with BOLD, CBF, and CBV contrasts in the cat visual cortex (Zhao et al., Neuroimage, 2006; Jin & Kim, Neuroimage, 2008; Kim & Kim, JCBFM, 2011), and underpinning neural sources in rat olfactory (Poplawsky et al., J of Neurosci, 2015) and mouse somatosensory models.  I will present neural sources of laminar fMRI, and discuss outstanding issues and implications for laminar-resolution fMRI in humans.
