Method Abstract:"[Investigators] report the characterization of three previously unidentified tectal cell types that are specifically labeled by dlx5/6 enhancer elements. In vivo laser-scanning microscopy in conjunction with ex vivo array tomography revealed that these neurons differ in their morphologies, synaptic connectivity, and neurotransmitter phenotypes."
Comments p.5 right column bottom paragraph:"Visualization of bsPVIN [bistratified periventricular interneurons] arbors in the plane orthogonal to the synaptic layers, as shown in Figure 4C, revealed that both of these arbors were very precisely targeted. The average thickness of the SGC [stratum griseum centrale] targeted arbor was 6.8 ± 0.7 μm (n = 11) and the average thickness of the SFGS [stratum fibrosum et griseum superficiale] targeted arbor was 5.5 ± 0.4 μm (n = 11). The width of the bsPVIN arbors in the plane of the neuropil layers revealed that the deeper SGC arbor is significantly wider than the more superficial SFGS arbor, which may have important implications for visual processing in the tectum."
