Here are some images that I've captured of my immunohistochemistry-stained brain tissue using a Leica Confocal TCS SP8 DLS microscope.
Parvalbumin interneurons (red), myelin (green), caspr (white) in the prefrontal cortex
Satellite oligodendrocytes (green) sitting in an unusual association with the parvalbumin (PV, blue) cell body and its associated perineuronal net (red). This image encapsulates the main finding of my PhD research, which is that the extracellular specializations surrounding PV undergo plasticity in a learning-dependent manner.
