The Feline Dorsal Nerve of the Penis Arises from the Deep Perineal Nerve and Not the Sensory Afferent Branch
Open accessAbstract
Summary: The cat has been used extensively as an animal model for urogenital studies involving the pudendal nerve. However, discrepancies persist in the literature regarding the origin of the dorsal nerve of the penis (DNP). This study used gross dissections and serial histological cross sections to demonstrate that the DNP arises from the deep perineal nerve and not the sensory afferent branch as previously reported. This finding indicates a better than previously appreciated neuroanatomical homology between the cat and human.

The authors developed a novel, high electrode-density (25 electrodes/mm2), high electrode-count (48-96 electrodes) penetrating neural interface designed for stimulation and recording in sub-millimeter neuroanatomical structures, such as small diameter nerves (<2 mm).
“We have developed a novel, high electrode-density (25 electrodes/mm 2 ), high electrode-count (48-96 electrodes) penetrating neural interface, designed for use in stimulation and recording in sub-millimeter neuroanatomical structures, such as small diameter nerves (<2 mm) like the rat sciatic [37], feline pudendal [38], or feline/human cochlear nerves [46].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
