摘要

利用电子计算机平均叠加技术在40例家兔上记录到一侧颈迷走神经（CVN）传入冲动投向两侧大脑皮层的躯体-内脏感觉区

并呈现一个范围约为4×4mm

的迷走神经-诱发电位（VEP）中心区。刺激强度由弱到强可以相继使CVN内的不同纤维（A

、A

和C）兴奋

同时可在皮层上记录到相应的不同传导速度的三类诱发电位即A

-VEP、A

-VEP和C-VEP。其中A

-VEP和C-VEP不被阳极电流阻滞

但可被普鲁卡因浸润所减弱。电针可以抑制这种反映内脏信息的VEP

抑制性质是速升速降的。推测这是针刺和迷走神经两种传入信息在CNS内相互作用的结果

Abstract

Experiments were performed on 40 rabbits. The evoked potential was elicited by stimulation of the central end of the cervical vagus nerve with electrical pulses of various intensities. This vagus nerve was blocked by a polarizing current so as to excite different kinds of fibers (A

A or C) in it. The cortical potentials were evoked mainly by stimulating A and C fibers of vagus nerve.The cortical specific representation of vagal evoked potential (VEP) is relatively concentrated. The protective area 2-5mm lateral from sutura sagittalis and 2-5mm posterior to sutura coronalis. It corresponds the somatovisceral sensory area of the cerebral cortex.Electroacupuncture of "Naiguan" and "Waiguan" points

the VEP decreased in 1 out of 18 experiments

increased in 2

remained unchanged in 2. It was suggested that the modulation of visceral afferents by acupuncture is corrected with the various functional situations.
