The claustrum receives projections from wMI but not from wSI. A, A′, Nissl-stained section of wMI with adjacent section showing an FR injection in the right Agm (arrowheads). B, B′, Nissl-stained section showing a BDA injection in the right wSI. Dense BDA labeling appears in VPM and POm of the thalamus. C, Nissl-stained section of the left claustrum 1.5 mm rostral to bregma. D, D′, Dense FR-labeled but no BDA-labeled terminals in the claustrum. E, Nissl-stained section of the right claustrum, 1.5 mm rostral to bregma. F, F′, Weak FR-labeling in right claustrum, but no BDA labeling. G–J′, Similar patterns appeared in the left (G–H′) and right (I–J′) claustrum in sections 500 μm caudal to bregma. Scale bars: A, 0.5 mm; B, 1 mm; C, 250 μm; D, 100 μm. NS, Neostriatum; rf, rhinal fissure.

The claustrum projects to wMI and wSI. A, A′, Injection of TB in the right wMI. B, B′, Injection of FG in the right wSI. D, Reconstruction of retrogradely labeled neurons in the left and right claustrum showing intermingled TB (blue) and FG (gold) labeled neurons. Double-labeled neurons are shown in green. Arrowheads correspond to confocal images obtained from the claustrum in the left (C) and right (E) hemispheres. The most prominent double-labeled neurons are indicated with red arrows. Scale bar: A, 0.5 mm; C, 50 μm; D, 1 mm. ac, Anterior commissure; cc, corpus callosum; ec, external capsule.

The same claustral region receives wMI inputs from both hemispheres and projects to the ipsilateral wSI. A–C, AF and FR injections in wMI of the left and right hemispheres, respectively. D–E′, FG injection in the right wSI. G, Bilateral reconstructions of tracer labeling in the claustrum. AF- and FR-labeled terminals shown as green and red dots, respectively; FG-labeled neurons shown as gold circles. F, H, Arrowheads indicate sites for confocal images from left (F) and right (H) hemispheres. Dense AF and FR terminal labeling surrounds FG-labeled neurons on both sides. Scale bars: A, E, 0.5 mm; D, 1 mm; F, 50 μm; G, 1 mm. ac, Anterior commissure.
