The electrical activity of the dorsal and ventral divisions of the hippocampus was investigated quantitatively during the development of discriminative operant training and defensive conditioning. Signal-related (respondent, sign-tracking) and goal-directed (operant, 'voluntary') activities and their hippocampal electrical correlates were compared. Signal-related behaviour was accompanied by significantly higher frequency spectral peaks than lever press behaviour. Spectral peaks were higher during lever pressing in early stages of training as compared to criterion performance. In defensive conditioning overt sign-tracking behaviour disappeared but spectral peak shifts toward higher values upon signal presentation persisted. Comparison of dorsal and ventral hippocampal activity revealed high coherence values and similar frequency shifts during behaviour transitions. These findings argue against suggestions that a close relationship exists between elementary motor acts and hippocampal EEG.
在辨别性操作训练和防御性条件反射的发展过程中，对海马体背侧和腹侧部分的电活动进行了定量研究。比较了信号相关（应答性、符号追踪）和目标导向（操作性、“自愿”）活动及其海马体电相关物。与杠杆按压行为相比，信号相关行为伴随着显著更高的频谱峰值。与标准表现相比，训练早期杠杆按压时的频谱峰值更高。在防御性条件反射中，明显的符号追踪行为消失，但信号呈现时频谱峰值向更高值的偏移持续存在。海马体背侧和腹侧活动的比较显示，在行为转换过程中具有高相干值和相似的频率偏移。这些发现反驳了关于基本运动行为与海马体脑电图之间存在密切关系的观点。
