Distribution of dopaminergic neurons in the brain of adult
medaka To examine the distribution of dopaminergic neurons in
medaka brain, we used immunohistochemistry of TH to visualize
dopaminergic neurons. We identified TH immunopositive (TH+)
fibers in the telencephalon (Fig. 1B). This TH+ structure in the
teleost brain is relevant to the striatum in the human brain (Rink
and Wullimann, 2004).
