Title: Precise quantification of natural behavior with computer vision Abstract: To understand the neural control of movement, cognition, and social interaction, we need to precisely quantify motor behaviors. Deep learning tools now enable to extract meaningful behavioral signals from raw videos, in high spatiotemporal resolution. These technologies are gaining increasing adoption in system neuroscience and…

Title: Multimodal Learning from Pixels to People Presenter: Carl Vondrick Abstract: People experience the world through modalities of sight, sound, words, touch, and more. By leveraging their natural relationships and developing multimodal learning methods, my research creates artificial perception systems with diverse skills, including spatial, physical, logical, and cognitive abilities, for flexibly analyzing visual data. This multimodal…

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…
