Evidence of neuroinvasion in postmortem COVID-19 patient brains (Brodmann area 6 and midbrain). FFPE sections of brain tissue from COVID-19 patients were stained using anti–SARS-CoV-2-spike antibody. (A) Images of regions of Brodmann area 6 of patient 1. Images are also shown in Fig. 4. (B) Images of regions of patient 2.(C) Images of regions of the caudate of patient 3.(D) Example image from control patient brains. Scale bar = 200 µm for zoomed-out images and 20 µm for zoomed-in images.
