I do computational neuroscience, so I write the program that specifies which steps to run in which order. Increasing confidence in one’s clinical assessment of awareness state. We find are associated with either conscious or unconscious brain activity-thus With the resultsįrom our analysis, clinicians can use neuroimaging tools such as EEG or ECoG toĬompare a new patient’s brain connectivity profile to the connectivity profiles Prevent any movement-meaning that anesthesiologists must rely on variousīiomarkers to assess whether someone is truly unconscious. Patients who undergo general anesthesia are typically given a paralytic to Probe them and ask if they’re having any sort of conscious experience. A patient could be in a coma, but there’s no way to Practical implication of this research is to be able to non-invasively assess Then we combine all of those models together to Have multiple subjects, multiple awareness states, multiple regions of theīrain, and multiple channels, and every minute of that data has its own One else has had such a large data set with this many connectivity models. There are 100 to 200 channels per patient spanning roughly 30 toĤ0 regions of interest in the brain, and we want to estimate how all of theseĭifferent channels are causally influencing each other. N1, N2, N3, REM) and multiple arousal levels under anesthesia (wake, sedated, University of Iowa placed electrodes directly on the cortical surface of theīrains of five patients and traced them through multiple stages of sleep (wake, In the course of surgery to help prevent seizures, our partners at The It’s still one of the biggest medicalĭata we use comes from high-dimensional recordings of patients with epilepsy. It’s a hot topic of interest, because people don’t really Requires analysis of data that shows how the brain is changing across different Under different states of awareness, different parts of the brain are communicating with each other, so we are looking for the neural correlates for conscious experience. We are trying to find signatures for consciousness by looking at the brain and how it processes sensory information. Our lab focuses on how general anesthesia induces loss of consciousness, as well as how the brain changes under anesthesia and during sleep. Matthew banks madison series#This is one in a periodic series on CHTC projects facilitated at Morgridge. In 2019, the center worked with 290 researcher groups and processed more than 390 million hours of computing time. The Center for High-Throughput Computing (CHTC), led by Morgridge Institute Investigator Miron Livny, provides UW-Madison scientists with the computing power to vastly increase the size and complexity of their research problems. But the challenge isn’t just gathering the data - it’s making sense of the billions of data points we are capable of generating. About this storyĭata science is changing the face of biology. Outside the lab, Chris leads an artificial intelligence club he co-founded in 2017 which offers AI-related workshops, tutorials and special projects to the campus community. He believes that understanding the brain as a computational system will help pave the way for developing new treatments to psychiatric disorders as well as developing novel artificial intelligence models. As an aspiring computational neuroscientist, Chris specializes in extracting insights from high-dimensional electrophysiological datasets to better understand how different regions of the brain function together in concert to produce a seamless conscious experience. Christopher Endemann is a research intern in Professor Matthew Banks’ research lab in the department of anesthesiology, which focuses on understanding how the brain changes when we lose and regain consciousness.
