Discovering how neural circuits process information requires measurement of neural activity on many different scales, ranging from single synapses to large assemblies of neurons, best in the brain of behaving animals. The study of brain function at the microscopic and mesoscopic scale has been revolutionized by novel approaches combining the development of molecular tools and gene transfer methods with newly designed instruments that use light to visualize and manipulate the activity of synapses, neural cells and neural ensembles. This international symposium will bring together world experts to present their latest discoveries and technological developments regarding brain connectivity, focusing on studies of synaptic, neuronal and network structure and function using microscopic imaging, connectomics, and optogenetics.
Improved technologies in the field of neuroscience are particularly important to tackle the great challenges in mapping the connections and interactions within and between highly complex neuronal networks. For example, super-resolution light microscopy now enables the visualization of individual molecules within a synapse; novel 3D imaging approaches enable the mapping of synaptic inputs onto dendritic trees and signalling within neuronal populations to be ‘read out’ at millisecond time scales; new viral tracing methods and novel instruments based on automated electron microscopy, optical microscopy and image reconstruction methods assist comprehensive connectomic approaches towards full reconstruction and analysis of synaptic circuits in 3D; furthermore, fast two-photon imaging makes it possible to monitor neural network activity deep in tissue in behaving animals; and recent advances in optogenetic and pharmacogenetic methods are complementing structural and functional imaging by allowing specific manipulations of the activity of particular cell types or neural pathways.
These multidisciplinary challenges and many others will be addressed at this meeting. It will be a great opportunity to foster new collaborations to undertake novel challenges that will push further our ability to detect, measure, manipulate and follow the intricate components of neuronal and network function.
