Figure 6. Hematoxylin and eosin stained section of normal non-human primate brain imaged in Figure 5.

Figure 6

A. Black and white photo of H&E stain of NHP brain showing the altered parenchyma around the proximal cannula (white arrow). White box depicts the region of the CED infusion noted on Figure 5. Bar is 2 mm in length. B. Low power photomicrograph of region demarcated by white box. This represents the parenchyma infused as seen in the T1-weigthed image of Figure 5. Bar is 500 μm in length. C. Higher power photomicrograph of inset region, showing no inflammatory cellular infiltrate or other evidence of trauma related to the tip of the catheter in this region. The CED infusion perfused the tissue but did not cause a parenchymal tear. Bar is 50 μm in length.
