Students will learn principles of optical and electron microscopy for imaging the brain at cellular resolution to understand the neuronal basis of behavior. The module will cover the quantification of behaviour in freely moving animals. Students will learn multi-photon (two- and three-photon microscopy) based imaging of neuronal populations in the brains of behaving rodents and fish as well as the use of serial electron microscopy to reconstruct synaptic connectivity. In addition, the module will introduce methods and tools for analysing large-scale imaging data.
