In the An excellent, the bigger device began capturing during the systole, just like the faster tool proceeded to flames during diastole

4 Hz) early in systole; the brand new indicate capturing rate of particular D muscles within nadir was twenty two ± sixteen Hz. The main section out of difference in the new conduct regarding particular D and kind C muscles (maybe not portrayed) would be the fact type C fibres was indeed silent at the nadir (look for Dining table step one)

Record of two type D baroreceptors. The frequency of the larger unit is shown in the bottom trace. At low pressures (left of A) both receptors fired during diastole. P th for the larger unit is the pressure at A, while P th for the smaller unit is the pressure at B. From their respective P th values each fibre showed an increase in firing rate with increasing pressure. The mean discharge for the larger unit was identical at the lowest and highest pressures shown in this figure (six action potentials per cycle)

We used ramps of increasing pressure to examine the discharge characteristics of the baroreceptors. (more…)
