SUMMARY:CNC Presents: Farzaneh Najafi\, PhD (Georgia Institute of Technology)
DESCRIPTION:“Temporal signaling\, not predictive processing\, shapes cell type specific dynamics in visual and parietal cortex”\nNeural activity following regular sensory events can reflect either elapsed time since the previous event (temporal signaling) or temporal predictions and prediction errors about the next event (temporal predictive processing). These mechanisms are often confounded\, yet dissociating them is essential for understanding neural circuit computations. We addressed this by performing two-photon calcium imaging from distinct cell types (excitatory\, VIP and SST) in layer 2/3 of visual (VIS) and posterior parietal cortex (PPC)\, while awake mice passively viewed audio-visual stimuli under temporal contexts with different inter-stimulus interval (ISI) distributions. Computational modeling revealed distinct functional clusters of neurons\, including stimulus-activated (ramp-down) and stimulus-inhibited (ramp-up) categories\, with distinct kinetics and area/cell-type biases. Importantly\, all functional clusters were invariant to temporal predictability\, shifted immediately when temporal statistics changed\, and were identical between naive and experienced mice. Population decoding revealed that clusters with heterogeneous kinetics differed in how well they represented interval information\, such that together they tiled elapsed time and produced a distributed\, learning-independent population code for time. These results provide strong evidence against temporal predictive processing in Vis/PPC under passive conditions and instead demonstrate intrinsic coding of interval timing\, redefining the mechanistic origin of ramping and omission-related activity in sensory cortex. We discuss how these dynamics align with stimulus-reset attractor frameworks\, and propose that temporal predictive processing is more likely implemented in other circuits or recruited in Vis/PPC during task-engaged behavior. \n Health Sciences G328

SUMMARY:NAPE Center Seminar Series: Larry Zweifel\, PhD (UW Psychiatry & Behavioral Sciences)
DESCRIPTION:“Molecular approaches for resolving the regulation of the midbrain dopamine system”\nWe have developed multiple molecular approaches to perform comprehensive analysis of the genetic heterogeneity midbrain dopamine neurons\, the circuits that control them\, the signaling pathways that regulate them\, and the ion channels that give them their signature encoding properties. I will summarize our current views on how the system is organized to mediate its many functions. \n  \n Health Sciences K069

SUMMARY:NBIO Presents: Pavan Ramdya\, PhD (Ecole Polytechnique Federale de Lausanne)
DESCRIPTION:“How flies learn to engage with objects and each other”\nA central goal shared by neuroscience and robotics is to understand how systems can navigate and act autonomously in complex environments. While extensive research has revealed how the visual system segments natural scenes into distinct components—insights that have inspired advances in computer vision and robotics—the next crucial challenge remains: learning the properties of these objects and responding appropriately. In this talk\, I will present our work using the fruit fly Drosophila melanogaster to investigate how the brain learns about objects and other animals in its environment\, and how it uses that information to guide behavior. By integrating quantitative behavioral analysis\, genetic manipulation\, connectomics\, and neural recordings\, we aim to uncover the neural mechanisms that enable flexible\, adaptive interactions with the world. \n Health Sciences G328 and Zoom

SUMMARY:NBIO Presents: Tenzin Ngodup\, PhD (Virginia Merrill Bloedel Hearing Research Center\, UW)
DESCRIPTION:“Unraveling the Cellular and Synaptic Architecture of the Cochlear Nucleus“\nUnderstanding how the brain processes sound starts with identifying its basic cellular components. Using modern profiling methods\, we have uncovered a rich and previously unappreciated diversity of neuronal types in the lower auditory system. These findings provide a new framework for understanding the synaptic signaling\, neuromodulation\, and circuit organization in the auditory brainstem. \n Health Sciences G328 and Zoom
