Exposure to Allergen Causes Changes in NTS Neural Activities after Intratracheal Capsaicin Application, in Endocannabinoid Levels and in the Glia Morphology of NTS

Figure 2

Example of ratemeter records which illustrate the spontaneous activity of NTS neurons before and after capsaicin administration (hollow arrow). (a) control rat, (b) ovalbumin-sensitized rat. A single oscilloscope trace (2 min recording) shows spontaneous activity of a single unit (long black arrow) immediately before and after intratracheal capsaicin application. Small black arrowheads indicate single vagal stimulations. Scale bar = 1 min.
