Abstract

In the tortoise, Gopherus polyphemus, single unit spikes in the olfactory epithelium in response to amyl acetate were positive relative to the slow potential. The number of spikes in a response train was 4 to 15, the duration 3 to 4 msec, the height 0.5 to 2 mv. The height of successive spikes in a train decreased. The decrement in height, the number, and the frequency of spikes changed with the strength of the odor.

摘要

在沙漠陆龟（Gopherus polyphemus）中，嗅上皮对醋酸戊酯产生的单个单位峰相对于慢电位呈正向。反应序列中的峰数为4至15个，持续时间为3至4毫秒，高度为0.5至2毫伏。序列中连续峰的高度会降低。峰的高度递减、数量以及频率会随气味强度而变化。
