EEG and DC activity were recorded from the hippocampus and neocortex in freely moving rats during consummatory behavior elicited by electrical stimulation and application of KC1 or norepinephrine to these structures. Eating induced by KC1 application or electrical stimulation of the neocortex or hippocampus was accompanied by single or multiple waves of spreading depression (SD), i.e., by traveling slow potential change. An analysis of single vs. multiple cortical SD waves indicated that when multiple waves occurred, feeding was elicited by the first wave. Injection of norepinephrine into the hippocampus resulted in a significantly larger and qualitatively different feeding response compared to KC1 injections. No apparent changes in the EEG or DC activity occurred upon norepinephrine injections.
在自由活动的大鼠中，通过对海马体和新皮质施加电刺激、氯化钾或去甲肾上腺素引发 consummatory 行为时，记录其脑电图（EEG）和直流（DC）活动。由氯化钾应用、新皮质或海马体的电刺激诱导的进食伴随着单个或多个扩散性抑制波（SD），即缓慢传播的电位变化。对单个与多个皮质 SD 波的分析表明，当出现多个波时，进食是由第一个波引发的。与注射氯化钾相比，向海马体注射去甲肾上腺素会导致明显更大且性质不同的进食反应。注射去甲肾上腺素后，脑电图或直流活动未出现明显变化。
