Featuring Dr. Danielle Bassett, "Perturbation and Control for Human Brain Network Dynamics."
The human brain is a complex organ characterized by heterogeneous patterns of interconnections. Non-invasive imaging techniques now allow for these patterns to be carefully and comprehensively mapped in individual humans, paving the way for a better understanding of how wiring supports our thought processes. While a large body of work now focuses on descriptive statistics to characterize these wiring patterns, a critical open question lies in how the organization of these networks constrains the potential repertoire of brain dynamics. In this talk, Dr. Bassett will describe an approach for understanding how perturbations to brain dynamics propagate through complex wiring patterns, driving the brain into new states of activity. Drawing on a range of disciplinary tools – from graph theory to network control theory and optimization – she will identify control points in brain networks and characterize trajectories of brain activity states following perturbation to those points. Finally, she will describe how these computational tools and approaches can be used to better understand the brain's intrinsic control mechanisms and to inform stimulation devices to control abnormal brain dynamics, for example in patients with medically refractory epilepsy.
General Event Info: The Neuroimaging Club serves as a forum for faculty, post-doctoral fellows, and students in Biomedical Engineering, Neurobiology, Neurology, Neurosciences, Psychiatry, Psychology, Vision Sciences, and Radiological sciences, to facilitate inter-disciplinary exchange of current imaging technology, methodologies, and applications. We meet on Fridays at 12 pm. Pizza is provided!
