刺激阴茎背神经（DNP）引起的皮质诱发电位提供了一个独特的机会来记录男性性感觉表征的皮质定位。DNP为人类阴茎的主要部分提供感觉轴突，包括阴茎轴和龟头。动物和人类研究表明，这种神经在勃起和射精中起着至关重要的作用。在接受癫痫病灶切除术前评估的患者中记录了对DNP电刺激的直接皮层诱发反应。这些研究提供的证据表明，初级感觉皮层包含一大片专门用于DNP传入纤维的皮层，并且感觉场位于与先前描述的不同的位置。这种反应的位置和分布表明需要修正传统的感觉皮质小丘的概念。
Cortical evoked potentials resulting from stimulation of the dorsal nerve of the penis (DNP) provide a unique opportunity to document the cortical localization of sexual sensory representation in man. The DNP supplies sensory axons to the major portion of the human phallus, including the penile shaft and glans. Animal and human studies indicate that this nerve plays a crucial role in erection and ejaculation. Direct cortical evoked responses to DNP electrical stimulation were recorded in patients undergoing preoperative evaluation for resection of epileptic foci. These studies provided evidence that the primary sensory cortex contains a large area of cortex devoted to the afferent fibers of the DNP and that the sensory field is in a different location than previously described. The location and distribution of this response indicated the need for revision of the traditional concept of the sensory cortical homunculus.
