Title: Mapping the landscape of social of social behavior using high-resolution 3D tracking of freely interacting animals Presenter: Ugne Klibaite, PhD Harvard University, Department of Organismic & Evolutionary Biology (PI, Bence P. Ölveczky) Abstract: Social interaction is a fundamental component of animal behavior. However, we lack tools to describe it with quantitative rigor, limiting our understanding of…

Title: Brain-wide credit assignment: cortical and subcortical perspectives Abstract: The brain assigns credit to trillions of synapses remarkably well. How the brain achieves this feat is one of the great mysteries in neuroscience. Recently, we have introduced Bursting cortico-cortical networks, a computational model of hierarchical credit assignment that captures a large number of biological features while approximating…

Title: Multiplexing multiple signals in neural codes: new statistical tools and evidence Abstract: How the brain represents multiple objects is mysterious. Sensory neurons are broadly tuned, producing overlap in the populations of neurons potentially activated by each object in the scene. This overlap raises questions about how distinct information is retained about each item. I…

Title: Brain Decodes Deep Nets Presenter: Jianbo Shi, PhD GRASP Laboratory Computer and Information Science University of Pennsylvania Abstract: We developed a surprising usage of brain encoding: using a brain fMRI prediction model to draw a picture of how a deep net processes information onto a brain.  Our tool provides a detailed analysis of large pre-trained vision models…
