The cortical processing of cardiac afferent input can be studied by means of event-related potentials (ERP), in which characteristic brain waves are seen to accompany rhythmic activity of the heart. In the present paper, results from three studies, investigating the heartbeat-evoked potential are summarized. These studies demonstrated that (a) cardio-afferent input is projected primarily to fronto-cortical areas; (b) typically, this activity is reflected as a broad positive wave form in a range of 300-600 ms after the EKG R-wave; (c) psychological factors such as level of attention and motivation exert influences on the heartbeat-evoked potential which are comparable to effects known from exteroceptive evoked potentials. On the basis of these data we infer that cardio-afferent input is for the most part transmitted along visceral fibers and that the cortical processing of cardiac activity is similar to the processing of external stimuli.
心脏传入输入的皮质处理可以通过事件相关电位（ERP）来研究，在这种情况下，可以看到特征性脑电波伴随着心脏的节律性活动。在本文中，总结了三项关于心跳诱发电位的研究结果。这些研究表明：（a）心脏传入输入主要投射到额叶皮质区域；（b）通常，这种活动在心电图R波后300 - 600毫秒的范围内表现为一个宽的正波形；（c）注意力水平和动机等心理因素对心跳诱发电位有影响，这与已知的外感受性诱发电位的影响相当。基于这些数据，我们推断心脏传入输入大部分是沿着内脏纤维传递的，并且心脏活动的皮质处理类似于外部刺激的处理。
