Fig. 7.
mHCN1 is expressed in selected nuclei in the brainstem and spinal cord. A, Coronal section (bregma, −6.24) showing labeling of ventral cochlear nucleus (vc), spinal trigeminal nucleus (sp), and facial nucleus (7) by mHCN1 probe. Weak labeling of vestibular nuclei is also visible. B, Serial section showing labeling by mHCN2 probe. C, Coronal section (bregma, −7.08) showing labeling of hypoglossal nucleus (12) by mHCN1 probe. Weak labeling of spinal trigeminal and lateral reticular nuclei, as well as of inferior olive (io) is also visible. D, Serial section showing labeling by mHCN2 probe. E, Coronal section through thoracic spinal cord showing labeling by mHCN1 probe; notice strong labeling of the motorneurons in the ventral horn (arrowhead). F, Serial section showing labeling by mHCN2 probe. Scale bars, 500 μm.
