Striatal tyrosine hydroxylase immunopositive interneurons. (A) TH-Immunoreactive aspiny striatal neuron from a normal rhesus macaque monkey. (B) A Type I striatal EGFP–TH⁺ neuron stained with biocytin during whole cell recording from a striatal slice from an EGFP–TH⁺ mouse. The dendrites branch infrequently and exhibit sparse, spine-like appendages (a). (C) Shows a Sholl plot of the reconstructed neuron revealing the extents and close overlap of the dendritic and axonal arborizations. (D) Drawing tube reconstruction of the neuron shown in (B). Note the dense axonal arborization studded with varicosities (green dots), presumably axonal boutons.
