Spatial distribution of oxygen in brain tissues in vivo.

<p>(A) Sample points on the A line. The red dots indicate the sample points separated by 0.1 mm along the A line (<i>AP</i>, 0 mm; <i>LR</i>, 1.3 mm; <i>D</i>, 0.0~-9.0 mm). (B) The trail of microprobes on the A line. The red arrow points to the trail left by the microprobe along the A line in the brain tissue. (C) Po₂ values in different encephalic regions along the A line (n = 6). Po₂ values in the Cg and LV are much higher than those in other regions of the brain. (D) Sample points on the B line. The red dots indicate the sample points separated by 0.1 mm along the B line (<i>AP</i>, 3.6 mm; <i>LR</i>, 2.0 mm; <i>D</i>, 0.0~-6.0 mm). (E) The trail of microprobes on the B line. The red arrow points to the trail left by the microprobe along the B line in the brain. (F) Po₂ values in different encephalic regions along the B line (n = 6). Po₂ values in the DG, LV and 3 V are much higher than those in other regions of the brain.
