Fast multimodal neuroimaging for tracking whole-brain dynamics

Seminar: BIC Seminar | July 3 | 1-2:30 p.m. | 125 Li Ka Shing Center

Laura Lewis, Harvard MGH

Neuroscience Institute, Helen Wills

Many aspects of cognition take place on a timescale of hundreds of milliseconds, and measuring neural activity in this frequency range is essential for neuroscience. However, current non-invasive neuroimaging methods are not able to precisely localize oscillatory neural activity above 0.2 Hz. We show that fast fMRI acquisition enables the direct detection of neural oscillations with frequencies...   More >

7T MRI: A Game-changer for Imaging Neuroscience

Seminar: BIC Seminar | July 6 | 2-3:30 p.m. | 125 Li Ka Shing Center

Robert Turner, Max Planck Institute for Human Cognitive and Brain Sciences

Psychiatry as a branch of medicine relies on good systems neuroscience of the human brain. When fMRI was first invented in 1990-91, with its non-invasive high spatial resolution mapping of evoked brain activity, many researchers hoped that rapid progress would ensue in understanding mental illness. However, the hope-for gains have been slow to materialize. I argue that inadequate efforts have so...   More >

Imaging cortical columns and cortical layers at 7 and 9.4 Tesla: From sensory mapping to cognitive applications

Seminar: Neuroscience Seminar | July 7 | 1-2:30 p.m. | 125 Li Ka Shing Center

Rainer Goebel, Maastricht University

Neuroscience Institute, Helen Wills

Ultra-­high magnetic field (UHF) fMRI at 7 Tesla and higher enables measurement of human brain activity with sub-­millimeter spatial resolution allowing to differentiate brain activation at the mesoscopic level of cortical layers and columnar-­like feature clusters. Recent experiments show that it is possible to map known columnar organizations in specialised brain areas (e.g. V1-­V3, A1, hMT,...   More >
