Dorsal thalamus in Bengalese finches as shown in parasagittal series. We adopted
nomenclature from atlases and previously published literature as described in
the Methods section “Nomenclature of Dorsal Thalamus”. Note that
by DLM and DMP we mean the thalamic nuclei found only in songbirds which project
to cortical nuclei LMAN and MMAN of the song system, respectively, and not the
regions in non-songbird species that share the same names. Series of
Nissl-stained parasagittal sections moving from medial (a) to
lateral (f). Distance lateral is from midline in this figure is sum
of the number of sections from midline (determined as described in Methods)
multiplied by section thickness, but not adjusted to account for shrinkage due
to fixation. Abbreviations: DIP, dorsointermediate posterior nucleus, DLA,
dorsolateral anterior nucleus, DLL, dorsolateral lateral nucleus, DLP,
Dorsolateral posterior nucleus, DMP, dorsomedial posterior nucleus, Hb,
habenula, IC, inferior colliculus, OM, occipto-mesencephalic tract, PC,
posterior commissure. Scale bar in a is 500 μm. Left is
anterior, dorsal is up.
