Figure 3.

Examples of bronchomotor (P_Tr increase), respiratory (inspiratory inhibition) and cardiac (bradycardia) responses to repetitive (50 Hz) stimulation Compared with an intact cervical vagus nerve (left panel), in the contralateral re-anastomosed cervical vagus nerve (right panel) explored 6 months after surgery we noted an absence of both the bronchomotor and cardiac responses to vagal stimulation whereas the ventilatory response reappeared. P_Tr, tracheal pressure; EMG, electromyogram; ECG, electrocardiogram.
