Identification of tyrosine hydroxylase (TH)+ neurons in sagittal sections of zebrafish brains.
(A) Left panel: an illustration of the sectioning position; middle panel: TH+ immunoreactivity in a microsliced section of a 6-month-old zebrafish brain; right panel: TH+ neuron clusters found in this section. The red and blue circles indicate dopaminergic and noradrenergic neurons, respectively. (B) Left panel: an illustration indicating the sectioning position. The middle panel is an immunostaining of TH using a microsliced section of 6-month-old zebrafish. The right panel illustrates the TH+ neuron clusters in this section. The red and blue circles indicate dopaminergic and noradrenergic neurons, respectively. DC1–7: diencephalic catecholaminergic cluster. Abbreviations: AP, area postrema; LC, locus coeruleus; MO, medulla oblongata interfascicular zone and vagal area; OB, olfactory bulb; PO, preoptic region; POa, anterior preoptic region; Pr, dorsal pretectum; SP, subpallium.
