SOD1 Overexpression Preserves Baroreflex Control of Heart Rate with an Increase of Aortic Depressor Nerve Function

Figure 3

Original recording of PAP, ADNA (Raw ADNA), integrated ADNA (Int. ADNA), and ECG in aC57 mouse. Trace 1: PAP. Trace 2: ADNA occurred as rhythmic bursts that exhibited cardiac rhythmic patterns and was synchronous with PAP. Note: ADNA increased prior to AP increases. This is because the catheter for blood pressure measurement was inserted into the femoral artery. Trace 3: ADNA signal was integrated using a 10 ms time constant to obtain the Int. ADNA curve. The small boxes in the Int. ADNA trace enclose the intervals between ADNA bursts where signal noise can be measured. Trace 4: ECG. The R waves of the ECG signal were used to separate ADNA firing intervals automatically by Chart 5.2 (arrows).
