Understanding the neural basis of olfactory memory

支持人类活动的记忆被认为是随着细胞形态和活动的变化而嵌入大脑的。然而，记忆背后的机制还没有被很好地理解。通过关注成年果蝇的嗅觉记忆，这项研究旨在从细胞、突触和回路水平上了解记忆的机制。我们能够开发出一种方法，在单个动物身上创造记忆，同时从参与记忆的神经元集合中记录活动，并分析负责嗅觉记忆的大脑区域中神经元和突触的电特性。

Memory that supports human activity is thought to be embedded in the brain as changes in cellular morphology and activity. However, the mechanisms underlying memory is not well understood. By focusing on olfactory memory in the adult Drosophila, this study aimed to understand the mechanisms of memory at cellular, synaptic, and circuit levels. We were able to develop a method to create memories in individual animals, to record the activity simultaneously from an ensemble of neurons involved in memory, and to analyze electrical properties of neurons and synapses in a brain region responsible for olfactory memory.
