Abstract

The molecular organization of the brain and its synapses is highly regulated and closely related to their biological functions. In this chapter, we introduce several super-resolution imaging technologies for brain and synapses, including optical microscopy (STED, STORM), expansion microscopy, and secondary ion mass spectrometry (SIMS, NanoSIMS). Super-resolution microscopy allows for visualization of the localization and dynamics of fluorescently labeled molecules whereas mass spectrometry imaging provides information on chemical structure and molecular turnover of the brain and synapses. The general principle, pros and cons of each technology as well as experimental considerations, such as labeling and sample preparation methods, are presented. In addition, correlative optical and mass spectrometry imaging, which appears as a recent trend of brain and synaptic imaging, is also discussed together with selected relevant applications in this research area.
