Hunt Memorial Lecture\r\n\r\nMeasuring the Health of the Brain: From Global Networks to Local Biomarkers\r\nAbstract:\r\nHow do we measure the health of the brain? Unlike blood pressure or cholesterol, there is no single number that captures brain function. We are developing the Brain Entropy Index (BEI), a new measure that integrates thermodynamics, statistical modeling, and brain imaging to provide a global indicator of brain health. Using data from modalities such as EEG, fMRI, and MEG, the BEI can reliably separate healthy from diseased brains, offering promise as a universal screening tool.\r\n\r\nYet, just as a blood test might flag \u201cillness\u201d without specifying the disease, a global index cannot by itself identify the underlying condition. Neurological disorders are defined by distinct local network dynamics, and it is these dynamics that can give rise to robust biomarkers. One example is EpiScalp, a computational tool we developed to model local brain networks from scalp EEG. EpiScalp can differentiate true epilepsy from seizure-mimicking disorders and from healthy brains, providing a disorder-specific biomarker.\r\n\r\nTogether, these approaches demonstrate a two-tiered framework: global measures can screen for health versus disease, while local network dynamics serve as biomarkers that refine diagnosis and define specific conditions. More broadly, this talk will illustrate how concepts from systems & control theory, physics, and data science can converge to open new frontiers in neuroscience and medicine.\r\n \r\nBio:\r\nSridevi Sarma received a B.S. in Electrical Engineering from Cornell University, and an M.S. and Ph.D. in Electrical Engineering and Computer Science from Massachusetts Institute of Technology (MIT).

The central idea I will explore in this talk is that these familiar dynamics can also be inverted: giving up can be hard, and require strength of will, while perseverance and continued effort can be a manifestation of weakness. It is not uncommon to respond to adversity by doubling down and investing even more effort, rather than by despairing and giving up. I make a case that there is a general form of practical irrationality common to both succumbing to temptation and to the phenomenon of \u201cover-efforting,\u201d such that it might be theoretically fruitful to embrace a conception of weakness of will that includes both phenomena.\r\n\r\nAbout Professor Paul:\r\nSarah Paul's research concerns agency and the philosophy of mind, focusing on the nature of intention and belief.
