LS1.4: Imaging brain structure and function across different spatial and temporal scales
Session co-organisers: Angus Silver, David DiGregorio, Zoltan Nusser
Brain function is poorly understood. A key reason for this is that it is difficult to study the underlying mechanisms because they occur across a wide range of spatial and temporal scales. Here we focus on the development and application new imaging methods for studying synaptic neuronal and network function. This 2.5 day symposium will bring together leading experts, who will present their latest studies covering areas including the molecular properties of synapses (synaptomics), dendritic integration in neurons, in vivo functional imaging of neural populations and large scale connectivity (connectomics).
Contributions covering the applications of microscopy in this field, as well as developments in instrumentation and techniques, are strongly encouraged.
