Figure 3

Heat maps of zinc, copper, and iron concentrations in serial sagittal sections of olfactory bulbs and tracts. Tissue from three human subjects was scanned using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) to produce these heat maps. Lateral distance from the first scanned section to the last scanned section for each case were 1548 µm, 858 µm, and 1032 µm for PD1, PD2, and Normal cases, respectively. Scale bar: 1 cm.
