Expression of mHCN2 and mHCN4 in the mouse thalamus. A, Coronal section (bregma, −1.58) showing labeling of laterodorsal (ld), ventroposterior (vp), and reticular (nrt) thalamic nuclei by mHCN2 probe. Also visible is the labeling of cells in the medial globus pallidus (mgp). B, Labeling by mHCN4 probe of laterodorsal and ventroposterior thalamic nuclei. Weak labeling is also visible in the medial globus pallidus. Scale bar, 500 μm.
