title: Techniques for the lesion of the vomeronasal organ of the rat.
abstract: Two technical procedures were developed in order to suppress the vomeronasal organ (V.O.) of the rat. The organ was approached through the nasal or oral cavity and electrolytic or thermic lesions were respectively performed. For electrolytic lesions the projection of the organ on the nasal bone was first determined. After opening the nasal bones, the Vs. Os. were lesioned by way of an electric current applied through an electrode introduced between the mucosa and nasal septum. For thermic lesions, the projection of the V.O. on the palate's surface was determined. After opening this area and the underlying part of the maxillary bone, both Vs. Os. were cauterized.
