Supplemental figure 1. Cytoarchitecture and position of TRN. A, Low (left)- and high (right)-power brightfield photomicrographs of coronal sections through the rhesus monkey brain at an anterior thalamic level, immunostained for parvalbumin. B, Low(left)- and high (right)-power brightfield photomicrographs of coronal sections through the rhesus monkey brain at a posterior thalamic level, immunostained for parvalbumin. The inhibitory TRN and the perigeniculate nucleus (dotted outlines) cover most of the thalamus and the majority of neurons are PV+ (brown). Abbreviations: AV: nucleus anterior ventralis; Cau: nucleus caudatus; Cl: nucleus centralis lateralis; IC: capsula interna; LD: nucleus lateralis dorsalis; MDmc: nucleus medialis dorsalis, pars magnocellularis; MDpc: nucleus medialis dorsalis, pars parvicellularis; VA: nucleus ventralis anterioris; VAmc: nucleus ventralis anterior, pars magnocellularis; VLc: nucleus ventralis lateralis pars caudalis; VLo: nucleus ventralis lateralis pars oralis; VPI: nucleus ventralis inferior; VPLo: nucleus ventralis posterior lateralis pars oralis; VPM: nucleus ventralis posterior medialis.

Supplemental figure 2. The prefrontal sector of TRN. 3D-reconstruction of a rhesus monkey brain, rendered transparent to show the position, orientation and size of TRN (dark blue), and the prefrontal sector (cyan), extending in anterior, central and posterior parts of the nucleus. Clockwise from the top left corner the views are: rostral, medial, caudal and lateral.

Supplemental movie 1. The position of TRN in the rhesus monkey brain. 3D-reconstruction of a rhesus monkey brain showing the position, orientation and size of TRN (blue), covering like an umbrella the dorsal thalamus.

Supplemental movie 2. Small and large boutons from prefrontal cortex to TRN are often found on the same axon. 3D-reconstruction and projection of high resolution stacks of images captured as described in Methods. The stacks were imported in ImageJ, reconstructed in 3D and rotated, in 1o increments in the X, Y or Z axis, using the 3D-project plugin; this made it possible to distinguish whether boutons were part of the same or different labeled axons.
