BrainEx Cellular Effects (IMAGE) NIH/National Institute of Mental Health Caption Immunofluorescent stains for neurons (NeuN; green), astrocytes (GFAP; red), and cell nuclei (DAPI, blue) in the hippocampal CA3 region of brains either unperfused for 10 hours after death (left) or subjected to perfusion with the BrainEx technology (right). After 10 hours postmortem, neurons and astrocytes normally undergo cellular disintegration unless salvaged by the BrainEx system. Credit Stefano G.
