Figure 2. Representative photomicrographs of tyrosine hydroxylase-positive dopamine neurons from rats fed control or n-3 PUFA-deficient diets.

A. Control diet, 2x magnification (bar = 100 µm). B. Control diet, SNc, 100x magnification, (bar = 1 µm). C. Control diet, VTA, 100x magnification, (bar = 1 µm). D. Deficient diet, 2x magnification (bar = 100 µm). E. Deficient diet, SNc, 100x magnification, (bar = 1 µm). F. Deficient diet, VTA, 100x magnification, (bar = 1 µm). A–C and D–F are from the same animal, respectively, under the same light and staining conditions. Abbreviations: SNc – substantia nigra pars compacta. VTA – ventral tegmental area.
