摘要。蜜蜂蘑菇体区域的单细胞记录显示，大多数细胞对一种以上的方式作出反应。测试了五种不同的方式：光、气味、施加到触角或长鼻的糖水，以及触角的机械刺激（空气抽吸）。神经元的背景放电（自发）频率与记录部位相关，在花萼区域较低，在β叶区域较高。神经元的反应谱与记录位置之间没有相关性，不能简单地将单个细胞分为不同的类别。一些单位在记录过程中改变其响应模式;这被解释为在实验中不可控制的其他输入的指示。在气味、光线和糖水刺激下发现了持续数秒至数分钟的后效。嗅觉和味觉输入在激活多通道单位中起着重要作用。一些神经元在经过多次嗅觉条件反射后，对气味的敏感性增加。这些单位的灵敏度的增加与自发放电频率的增加相关。
ABSTRACT. Single cell recordings in the mushroom body area of the bee revealed that the majority of cells responds to more than one modality. Five different modalities were tested: light, scent, sugar‐water applied to the antennae or the proboscis, and mechanical stimuli of the antennae (air puffs). The background discharge (spontaneous) frequency of the neurons was correlated with the recording site, being low in the calyx area and high in the area of the β‐lobes. No correlation between the reaction spectra of neurons and the recording location was found. A simple classification of single cells into different classes is not possible. Some units change their response pattern during recording; this is interpreted as an indication of other inputs which were not controllable in the experiments. After‐effects, lasting some seconds to minutes, were found with scent, light and sugar‐water stimuli. The olfactory and gustatory inputs obviously play an important role in activating multimodal units. Some neurons showed increasing sensitivity for a scent after a number of olfactory conditionings. An increase of sensitivity in these units is correlated with an increase of the spontaneous discharge frequency.
