The paper identifies a cardiac neuronal subtype, NA1b, that increases in a murine dilated cardiomyopathy model and shows elevated M-current ion channels and neurodegenerative pathways.

The paper analyzes the morphometric features of postganglionic sympathetic neurons innervating the myocardium and finds they are multipolar and larger than those innervating forelimb skin.

The paper identifies distinct subtypes of cardiac-innervating sympathetic neurons using viral tracing and single-cell RNA sequencing, revealing their unique physiological roles in stress responses.
