Soledad Gonzalo Cogno Seminar Time: 11:30am Date: Wed 3/19/25 Location: JLG, L5-084 Title: Ultraslow patterns of neural population activity in the entorhinal-hippocampal circuit Note: Everything I will present in this talk is preliminary – Feedback and ideas will be very much appreciated! Abstract: The medial entorhinal cortex hosts many of the brain’s circuit elements for spatial navigation and…

ARNI is committed to promoting science education among New York City's youth. This year, ARNI is supporting Girls' Science Day on April 5, 2025. Location: TBD Mission Girls’ Science Day at Columbia University seeks to champion the advancement of women and underrepresented groups in the fields of science, technology, engineering, and math (STEM). By offering…

Title: Principles of Learning from Multiple Tasks Abstract:  Deep networks are increasingly trained on data from multiple tasks with the goal of sharing synergistic information across related tasks. A language model, for example, is trained on 10 trillion tokens on tasks ranging from programming, finance, trivia to translation and a vision model is trained on over a billion…

Speaker: Christopher A. Baldassano Title: Remembering events using schematic knowledge Abstract: Our everyday experiences consist of familiar sequences of events in familiar contexts, and we use our knowledge of the past to understand and remember the present. Research in my lab combines behavioral, eye-tracking, and neuroimaging methods to investigate how prior knowledge of temporal and spatial structure impacts…

Title: How the human brain thinks about itself Abstract: The human brain has a remarkable ability to monitor and evaluate its own mental states, known as metacognition. Metacognition is crucial to success, enabling us to recognise gaps in our knowledge and collaborate effectively. Problems with metacognition are linked to maladaptive behaviours, such as endorsing false…

Title: Quantifying individuality in neural circuit representations   Abstract: Signatures of neural computation are thought to be reflected in the coordinated activity of large neural populations. Neuroscience is now flush with measurements of these activity patterns in humans, animal subjects, and large-scale artificial network models. In this talk, I will address an extensively studied, yet unresolved, question: How should we quantify the extent to which…

Title: Reimagining the biology of memory   Abstract: Over the last half century, there has been a remarkable convergence on the idea that memories are stored at synapses. I will argue that this is only part of the story. A more complete story compels us to recognize the radical ubiquity of memory in living systems,…

Bio: Itzel is a Ph.D. student at Rice University working with Prof. Xaq Pitkow. She studies perception and control mechanisms that give biological organisms an advantage over machines. She believes understanding how the brain works using mathematical principles is essential to build the next generation of AI systems which are more robust, more general-purpose, less…
