Figure 5

Differential expression of K-Channel genes in the dorsal thalamus (DLM and Ov). Photomicrographs of in situ hybridizations for KCNA1, KCNAB1, and KCNH8 taken in adjacent parasagittal sections at a brain level that includes song nucleus DLM, and auditory nucleus Ov (approximate location is indicated in Figure 1; dotted lines approximate nuclear boundaries based on dark field illumination; thin lines denote myelinated fibers). K-Channel genes reveal highly selective expression in DLM and Ov (A and B), as well as Ov alone. (C). Scale-bar: 100 μm. See Abbreviations for a complete list of anatomical abbreviations.
