The effects of absorbing boundaries at the blood vessels. The effects of absorbing boundaries at the blood vessels. A) Waves persistently re-emerge close to the boundary in response to a short, 30 minutes, pulse of stimuli when p >= 105. The group of cells neighboring the source is locked in "high T"- state as shown by green color. B) The frequency of re-initiation is higher if the source is located closer to the absorbing boundary, here p = 83.
