Role of neurohumoral systems in beat-to-beat BPV in rats and humans.
| Frequency domain | Rats | Humans |
| Very low frequency | Myogenic vascular function, renin angiotensin system, endothelial-derived NO | Myogenic vascular function |
| Low frequency | Endothelial-derived NO, sympathetic nervous system | Sympathetic nervous system, myogenic vascular function |
| High frequency | Cardiac output | Endothelial-derived NO |

NO: nitric oxide.
