这些实验涉及陆生蜗牛 A. fulica 后触角的感觉上皮和神经节。用风速低至 25 毫米/秒的风刺激上皮细胞后，会引起细胞外的多单位反应。混合蔬菜的气味引起了少数记录地点的反应。细胞内记录（N = 60）是从两类神经元中获得的，一类暂时被鉴定为单极中间神经元，另一类为双极中间神经元。在出现食物气味后，两个被刺穿的神经元会做出小幅缓慢的去极化反应。每个细胞都会对某些气味做出一致的反应，而对其他气味则没有反应。
These experiments concerned the sensory epithelium and ganglion in the posterior tentacles of the terrestrial snail A. fulica. Extracellular, multi-unit responses were evoked after epithelial stimulation with winds, at velocities as low as 25 mm/s. The odor of mixed vegetables elicited a response at a minority of recording sites. Intracellular recordings (N = 60) were obtained from 2 classes of neurons, 1 tentatively identified as a monopolar interneuron, the other a bipolar interneuron. Two of the impaled neurons responded with small slow depolarizations after the presentation of food odors. Each cell consistently responded to certain odors, while failing to respond to others.
