Their findings show that the special glial cells help synapses grow and rearrange, demonstrating the essential role of microglia in brain development. Mutations on a single gene, the huntingtin gene, ...

Electron microscopy uses a beam of electrons to illuminate a sample and achieve much higher spatial resolution than light microscopy. Transmission electron microscopy generates an image of the ...

Using electron microscopy, the researchers examined postmortem brain tissues from Alzheimer's patients. They found that levels of dark microglia were twice as high in Alzheimer's patients compared ...
