行为是神经回路计算的结果,神经回路由感觉神经元和中间神经元之间的大量突触连接组成。负责学习和记忆的环磷酸腺苷反应元件结合蛋白(CREB)几乎在所有神经元中都有表达。然而,我们发现秀丽线虫CREB同源基因CRH-1只在单个双侧热敏神经元AFD中是与记忆相关的行为所必需的。在CREB缺失的CRH-1突变体的AFD中恢复CRH-1可以挽救其趋热缺陷,而在其他神经元中的恢复则不能。在钙成像分析中,CREB缺失的CRH-1突变体的AFD神经元对温度升高表现出异常的反应。我们提出了一个新的平台,用于分析神经回路内单细胞分辨率的行为记忆机制。
Behaviour is a consequence of computation in neural circuits composed of massive synaptic connections among sensory neurons and interneurons. The cyclic AMP response element-binding protein (CREB) responsible for learning and memory is expressed in almost all neurons. Nevertheless, we find that the Caenorhabditis elegans CREB orthologue, CRH-1, is only required in the single bilateral thermosensory neuron AFD, for a memory-related behaviour. Restoration of CRH-1 in AFD of CREB-depleted crh-1 mutants rescues its thermotactic defect, whereas restorations in other neurons do not. In calcium-imaging analyses, the AFD neurons of CREB-depleted crh-1 mutants exhibit an abnormal response to temperature increase. We present a new platform for analysing the mechanism of behavioural memory at single-cellular resolution within the neural circuit.
