动物对其环境的反应依赖于外部刺激对感觉神经元的激活。然而,在许多感觉系统中,神经元在外部刺激之前表现出基础活动。人们认为这种先前的活动可以调节神经功能,但它对动物行为的影响仍然难以捉摸。在这里,我们揭示了嗅觉受体神经元(ORN)先前活动在塑造幼虫嗅觉行为中的潜在作用。我们发现幼虫 ORN 的先前活性是由嗅觉受体复合物(OR 复合物)介导的。 Orco 是 OR 复合体功能所需的气味辅助受体,其突变会导致对 ORN 光遗传学激活的吸引力行为减少。钙成像显示 Orco 突变型 ORN 对光遗传学刺激完全做出反应,但表现出神经反应时间模式的改变。这些发现共同表明,果蝇幼虫 ORN 激活后的信息处理中的先前活动起着关键作用,这反过来又有助于嗅觉行为控制。
Animal responses to their environment rely on activation of sensory neurons by external stimuli. In many sensory systems, however, neurons display basal activity prior to the external stimuli. This prior activity is thought to modulate neural functions, yet its impact on animal behavior remains elusive. Here, we reveal a potential role for prior activity in olfactory receptor neurons (ORNs) in shaping larval olfactory behavior. We show that prior activity in larval ORNs is mediated by the olfactory receptor complex (OR complex). Mutations of Orco, an odorant co-receptor required for OR complex function, cause reduced attractive behavior in response to optogenetic activation of ORNs. Calcium imaging reveals that Orco mutant ORNs fully respond to optogenetic stimulation but exhibit altered temporal patterns of neural responses. These findings together suggest a critical role for prior activity in information processing upon ORN activation in Drosophila larvae, which in turn contributes to olfactory behavior control.
