Todd Coleman, Associate Professor of Bioengineering at Stanford University, will lecture on “Monitoring and modulating nervous systems in the brain and visceral organs” at 4:00 pm in 2269 Beckman Institute and on Zoom September 28, 2022.  One of our MBM trainees will give an introduction.

The lecture is free and open to the public courtesy of the Miniature Brain Machinery Program. Zoom details are below.

Abstract:

We will highlight recent technological and methodological advances in deploying miniaturized technologies that can monitor the electrophysiologic patterns of the visceral nervous system.  Specifically, we will showcase recent developments in biomedical signal processing that enable non-invasive tracking of the slow wave patterns associated with the neuromuscular activity of the stomach.

We will also describe recent developments of thin, stretchable, wireless biosensor patches that can be embedded within routinely used medical adhesives for ambulatory recording of these gastric electrophysiologic patterns.  We will illustrate how such systems can also be used in tandem with novel miniaturized pacing devices to enable closed-loop neuromodulation of the enteric nervous system.

We will also discuss recent efforts in exploring the electrophysiologic basis of the gut-brain axis with concurrent non-invasive electrophysiologic recordings of the brain and stomach. We will conclude with a summary of the knowns and unknowns in how multi-organ physiology research, technology miniaturization, and data science may create unique opportunities for the intersection of engineering, applied probability, neuroscience, and medicine.

Title: 

Advances in free-energy calculations at the dawn of exascale computing

Speaker: Chris Chipot, Adjunct Professor, Department of Biological Physics, The Centre National de la Recherche Scientifique, Paris, France 

In recent years, free-energy calculations have emerged as an indispensable tool to bridge the gap between molecular dynamics simulations and biological events, and help tackle deep biological questions that experiment alone has left unresolved. In spite of spectacular advances on the hardware front, which have paved the way for brute-force molecular dynamics to time and size scales hitherto never attained, free-energy calculations represent a cogent alternative to access with unparalleled accuracy the thermodynamics and possibly the kinetics that underlie complex processes of the living. In this lecture, I will review recent developments for free-energy calculations of both alchemical and geometrical transformations. In particular, I will show how combination of importance-sampling schemes can be used profitably to map with unprecedented efficiency and without any loss of accuracy complex free-energy landscapes from whence physically meaningful transition pathways can be extracted. I will compare this strategy with an alternative route consisting of a path search in multidimensional space followed by a potential of mean force calculation along the putative minimum free-energy pathway. I will also show how GPU-acceleration can be harnessed to boost free-energy calculations of an alchemical nature, and, thus, allow large sets of mutations to be performed in a routine fashion on affordable platforms equipped with GPUs. I will close discussing the hurdles free-energy calculations have overcome in recent years, and the challenges they are facing as we are at the dawn of exascale computing.

Title: "Integration of parallel ascending pathways in the primary and higher-order."

Speaker: Hiroyuki Kato, Assistant Professor, Department of Psychiatry and Neuroscience Center, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina

Information flow in the cortex is classically considered as feedforward-hierarchical computation. However, recent findings have started to reveal rather parallel and distributed processing. Dr. Kato will discuss his team's work studying parallel sensory pathways across the primary and higher auditory cortices in extracting complex sound features.

Hee Jung Chung, Associate Professor of Molecular and Integrative Physiology and Neuroscience at Illinois, will lecture on “The role of brain specific tyrosine phosphatase STEP in hippocampal excitability and seizures” at 4:00 pm in 2269 Beckman Institute and on Zoom October 5, 2022.  One of our MBM trainees will give an introduction.

The lecture is free and open to the public courtesy of the Miniature Brain Machinery Program. Zoom details are below.

Hee Jung Chung completed her PhD at Johns Hopkins University School of Medicine as well as a postdoctoral appointment at the University of California, San Francisco. Her research interests focus on neurological and behavioral disorders with an emphasis on the study of epilepsy.

The Chung Lab endeavors to understand how epilepsy mutations affect ion channel function and lead to hyperexcitability in inherited or de novo epilepsy, and identify molecular mechanisms that alter ion channels to cause hyperexcitability in acquired epilepsy. To investigate these two areas, they use interdisciplinary approaches including primary neuronal culture, live and fixed microscopy, biochemistry, electrophysiology, and mouse genetics.

Title: Coarse-grained modeling for nucleic acid nanotechnology.

Speaker: Petr Sulc, Assistant Professor, Center for Biological Physics, School of Molecular Sciences, Arizona State University, Tempe, Arizona.

DNA and RNA nanotechnology use designed nucleic acid strands to self- assemble large-scale nanostructures and devices. Computer simulations can provide valuable insights into their function but modeling such systems faces several challenges: The nucleic acid nanostructure assembly and function consists of rare events such as creation and breaking of base pairs, and their sizes are typically up to few thousands of nucleotides. Dr. Sulc will present a top-down coarse-grained model, oxDNA, which was specifically designed for simulations of DNA nanotechnology systems, and present examples where it has been used to help design and understand function of DNA, RNA and protein-DNA hybrid nanostructures and processes. In particular, Dr. Sulc will show the model's use to study of DNA origami tetrastack lattice design (a multicomponent nanostructure consisting of a million of nucleotides, with promising applications to metamaterial design), DNA and RNA strand displacement reaction (a fundamental mechanism in nucleic acid computing) and simulations of ATP-powered DNA leaf-spring engine. Dr. Sulc will also present our online browser-based tools for design of DNA and protein-DNA/RNA hybrid nanostructures and provide interactive in-browser simulations to help users design structures with desired function.

Title: "Edge-centric connectomics."

Speaker: Richard Betzel, Assistant Professor, Department of Psychological and Brain Sciences, IU Network Science Institute, Indiana University Bloomington, Bloomington, Indiana

Brains can be modeled as functional networks, where interregional connections and their weights are estimated as a correlations. Dr. Betzel will present an approach for exactly decomposing these connections (edges) into their time-varying contributions. This approach yields framewise estimates of networks across time and can be used to estimate the novel construct of "edge functional connectivity".

Title: "Regulation of liver energy balance by nutrient sensing nuclear receptors"

Speaker: David Moore, Professor and chair, Department of Nutritional Sciences & Toxicology, University of California Berkeley, Berkeley, California.

The liver is crucial for maintaining whole body energy balance. For example, it responds to fasting by secreting glucose and to feeding by both metabolizing it and storing it as glycogen. The nuclear receptors FXR and PPARα are activated in the fed or fasted liver, respectively, and regulate many basic metabolic processes. Dr. Moore's lab have found that both receptors also regulate processes that are not directly related to metabolic pathways but are central to liver energy balance. Dr. Moore's presentation will focus on the previously described roles of FXR and PPARα in control of autophagy and more recent results on control of the liver secretome.
