Graphical representation of the SARS-CoV-2 viral genome and qRT‒PCR values obtained from the different brain and lung regions. A VCN is represented on a coloured scale (black = not detected, light green = high expression, grey = material not available). The patients are shown in each row and sorted by the VCN value in their lung sample (« L» column, top to bottom as higher to lower values). The lateral bars indicate the number of brain regions for each patient where the viral genome was detected (y-axis) or the total number of patients showing the presence of the viral genome for each specific region (x-axis). Order of the tested brain regions from left to right: right brain resection, left brain resection, right stereoanterior, right stereoposterior, left stereoanterior, left stereoposterior, brainstem, dura-mater. B VCN values in a box-plot representation showing the limits of the 1st quartile, median and 3rd quartile, whiskers showing min/max values (black dots = lung, grey dots = brain regions, same vertical order as in A, x-axis showing exponential VCN increase with dashed lines marks validated standard curve limits)
