Figure 4. Co-registered images of 5HT-, GAD- and TH-IR staining: A, B, C: Three deconvolved images showing a convergence of monoaminergic inputs (arrows = 5HT; arrowheads = TH) to GABAergic cell bodies in rat mPFC. D. Monoaminergic varicosities converge on a pyramidal neuron (P) receiving GAD-IR terminals in rat mPFC. There also appear to be appositions between GAD-IR terminals and 5HT-IR varicosities (*). Similar interactions also seem to occur between GAD-IR terminals and TH-IR varicosities. Bar = 10 µm. (Pixelation is normal as part of the image gathering process from the microscope.)
