Fig. 2From: Standardization of methods to record Vagus nerve activity in miceComparison of neurograms recorded with hook and cuff electrodes. Baseline activity from the cervical vagus nerve was recorded for 10 min from Balb/c mice with either a hook (n = 72) or a cuff (n = 25) electrode. a Representative recording of the neural signals by three hook electrode in a 10 min window, b) The inset from (a) is expanded as a 2 s window, c) The inset from (b) is expanded as a 100 millisecond window with CAP’s indicated by the asterisk. d Representative recording of the neural signals recorded by the cuff electrode in a 10 min window, e) The inset from (d) is expanded as a 2 s window, and f) The inset from (e) is expanded as a 100 millisecond window with CAP’s indicated by the asterisk. g Addition of KCl (4 mM) indicated by the red line directly to the cervical vagus nerve causes depolarization and CAP’s to fire (indicated by asterisk). h) Pretreatment with 2% lidocaine inhibits the depolarization and subsequent CAP firing induced by the addition of KCl (4 mM) indicated by the red lineBack to article page
