蝗虫触角叶中的神经元已经被证明可以使用空间分布的同步神经活动模式来编码气味的身份。最近的工作描述了如何检测这种神经模式。通过使用非线性膜特性，一组目标神经元，蘑菇体的凯尼恩细胞，能够充当重合探测器，对同步活动敏感。此外，触角叶和蘑菇体之间的特定电路细化了凯尼恩细胞的时空选择性。在这个过程中，气味身份的神经表征从密集的时空代码转换为稀疏代码。
The neurons in the antennal lobe of the locust had been shown to encode the identity of odorants using spatially distributed synchronized patterns of neural activity. Recent work describes how such neural patterns are detected. By using non-linear membrane properties, one set of target neurons, the Kenyon cells of the mushroom bodies, are able to act as coincidence detectors, sensitive to synchronized activity. In addition, the specific circuitry between the antennal lobe and the mushroom body refines the spatial–temporal selectivity of the Kenyon cells. In this process, the neural representation of odor identity is transformed from a dense spatial–temporal code into a sparse code.
