Abstract

Low-intensity electrical stimulation of the olfactory bulb through a set of spatially distributed electrodes was used as a model in order to study the spatial basis of the olfactory coding, in rats. The results indicate that this multipolar stimulation can serve as a conditional stimulus in a learned aversion paradigm; in addition, water-deprived animals displayed high ability to discriminate and memorize various combinations of electrode positions paired with differently palatable solutions.

摘要

通过一组空间分布的电极对大鼠嗅球进行低强度电刺激，以此作为模型来研究嗅觉编码的空间基础。结果表明，这种多极刺激可作为习得性厌恶范式中的条件刺激；此外，缺水的动物表现出很强的能力，能够辨别和记忆与不同可口溶液配对的电极位置的各种组合。
