Abstract: The Anterior Pagoda neuron (AP) is one of the largest neurons in the leech nervous system. It receives multiple sensory inputs. The physiological function of AP is unknown. With the combination of intra-and extra-cellular electrophysiological recording methods, it is suggested that AP neuron modulates the membrane potential of multiple muscle cells in the contralateral body wall.

摘要： 水蛭前宝塔神经元(AP)是神经节前侧囊中胞体最大的神经元，它接受多种感觉传入，但传出功能未知。通过应用细胞内、外电生理学记录结合方法，揭示了AP神经元的输出效应可能是调制水蛭体壁肌肉细胞膜的兴奋水平。
