Abstract:听Understanding the molecular mechanisms underlying synaptic transmission is challenging in part because synapses are tiny, exhibit a wide range of shapes and internal structures and undergo activity-dependent plasticity. Optical nanoscopy allows us to characterize the molecular dynamics and interactions of synaptic proteins at their scale: the nanoscale. Developing AI-assisted frameworks for optical nanoscopy allows real-time optimization of multi-modal live-cell imaging as well as for quantitative high throughput image analysis. We developed AI approaches for: 1) quantitative analysis of neuronal protein organization in optical nanoscopy images and 2) the optimization of image acquisition schemes, especially in living neuronal samples. This allows us to characterize activity-dependent remodeling of synaptic nanostructures and localized modulation of synaptic activity. The development of data-driven microscopy is transforming our ability to discover and characterize rare phenomena that may influence synaptic connections and thus to discover new mechanisms influencing the proper functioning of our brain.
