Figure 3. Simultaneous recording of tail sympathetic activity and back skin CVC-type fibre activity.

Figure 3

A, chart record showing (from top): sympathetic unit activity recorded from a filament in the lateral collector nerve of the tail (tail SNA), sympathetic activity in a filament split from the nerve to back skin (back skin SNA), respiratory pressure and blood pressure. Filled dots and asterisks in the second trace (back skin SNA) indicate two discriminated single CVC-type units. Superimposed spike shapes of each discriminated single unit are shown at the end of their respective traces. B and C show arterial pulse-triggered (B) and respiratory pressure-triggered (C) histograms of tail SNA and back skin CVC-type fibre activity during cooling (bin size 10 ms in B and 100 ms in C; 949 tail SNA spikes and 1237 back skin CVC-type spikes counted in both B and C).
