Modulation of Vasomotive Activity in Rabbit External Ophthalmic Artery by Neuropeptides

Figure 1

Example of basal periodic oscillations in vascular tone observed before any drug administration. On the 𝑥 axis, the perfusion pressure recorded at the rabbit external ophthalmic artery is represented in mm Hg. In the 𝑦 axis, we represent the time in seconds.
