Visual identification of the recorded neurones in the caudal NTS (cNTS)

A, an infrared photomicrograph indicating the position of the patch recording pipette (p) and the stimulation electrode (s) in a 400-μm thick coronal slice from a 16-day-old rat. IV, the fourth ventricle; nTS, the nucleus tractus solitarii; TS, the tractus solitarius; dmnX, nucleus dorsalis motorius nervi vagi; XII, nucleus nervi hypoglossi. B, an infrared microscopic image of cNTS neurones in a slice from a 21-day-old rat. The recording pipette can be seen on the right. Scale bar, 50 μm. C, a confocal microscopic image of a cNTS neurone used in this study filled with lucifer yellow. Left, a coronal view; right, a reconstructed saggital view.
