Figure 3. GABAergic innervation of thalamic trigeminovascular neurons.

Figure 3

Left: Immunopositive VGaT synaptic vesicles (green) surrounding a thalamic dura-sensitive neuron (red) labeled with TMR–dextran. Nuclear counterstaining was performed with DAPI (blue). Arrowheads indicate close apposition of VGaT positive axons and the cell body and dendrites of the labeled neuron. Upper right: Location of the dura-sensitive neuron (red star) shown at left. Number in red indicates distance from bregma (mm). Lower right: Fluorescent images showing VGaT axonal labeling in thalamic Po and VPM nuclei. Scale bars = 100 µm. Abbreviations: eml, external medullary lamina; ic, internal capsule; ZI, zona incerta.
