Three Cynomolgus monkeys (Macaca fasicularis) learned a series of food-visual conditional discrimination problems. In each problem, 1 of 2 possible food items was presented at the beginning of each trial and acted as an instruction cue as to which of 2 visually distinct stimulus objects the monkey must displace on that trial to obtain a further food reward. Following surgical disconnection of olfactory-visual intrahemispheric interaction, the monkeys were unable to use olfactory properties of the food items to guide visual choices. These results show both that olfactory differences between foodstuffs are a powerful olfactory stimulus, which can enter into cross-modal association with visual stimuli, and that this association depends on an intrahemispheric pathway of olfactory-visual interaction.
三只食蟹猴（猕猴）学会了一系列食物视觉条件辨别问题。在每个问题中，每次试验开始时会呈现两种可能食物中的一种，作为一种指示线索，告知猴子在该试验中必须移动两个视觉上不同的刺激物体中的哪一个，以获得进一步的食物奖励。在嗅觉 - 视觉半球内相互作用通过手术切断后，猴子无法利用食物的嗅觉特性来指导视觉选择。这些结果表明，食物之间的嗅觉差异是一种强大的嗅觉刺激，它可以与视觉刺激形成跨模态关联，并且这种关联依赖于嗅觉 - 视觉相互作用的半球内通路。
