Histologists use a variety of techniques to study structural connectivity: - Microscopy: Light and electron microscopy are used to visualize cells and their connections at high resolution. - Staining: Various stains and dyes help to highlight different components of the tissue, making it easier to see connections. - Immunohistochemistry: Uses antibodies to detect specific proteins, helping to map out connections at the molecular level. - Tracing Techniques: In neuroscience, tracers can be used to map neural pathways and connections.
