The role of the anterior commissure in discrimination of and habituation to olfactory stimuli was studied in pigeons by measuring changes in the heart rate. In order to exclude any trigeminal response, we presented odorous stimuli to groups of pigeons with one olfactory nerve cut and either the ipsilateral or the contralateral nostril plugged. When the nostril involved in the experiments was on the same side of the cut olfactory nerve, the pigeons did not show any response, whereas they displayed changes in heart rate when the nostril tested was on the opposite side. In habituation transfer experiments were a control group of pigeons and a group with the anterior commissure cut, both of them subjected to a monolateral habituation training to amylacetate. Later, when the odour was presented to the opposite nostril, both groups maintained the habituation.
通过测量心率，研究了前连合在鸽子对嗅觉刺激的辨别和习惯化中的作用。为了排除任何三叉神经反应，我们对切断一侧嗅神经并堵塞同侧或对侧鼻孔的鸽子群施加气味刺激。当参与实验的鼻孔与切断嗅神经的一侧相同时，鸽子没有表现出任何反应，而当测试的鼻孔在对侧时，它们的心率会发生变化。在习惯化转移实验中，一组对照组鸽子和一组切断前连合的鸽子都接受了对乙酸戊酯的单侧习惯化训练。后来，当气味呈现给对侧鼻孔时，两组都保持了习惯化。
