正确的威胁-奖励决策对动物的生存至关重要。新出现的证据表明,运动系统可能参与决策,但这些功能的神经回路和分子基础知之甚少。我们在线虫中发现,GABA能运动神经元(D-MN)在威胁-奖励决策中通过逆行抑制控制回避神经回路中胆碱能运动神经元的一对运动前命令中间神经元AVA而偏向于奖励行为。D-MNS的这一功能是由AVA中一种特异性的离子型GABA受体(UNC-49)介导的,并依赖于两个AVA中间神经元之间的电耦合。我们的结果表明,AVA是中枢神经元,来自威胁和奖赏的感觉输入和来自D-MN的运动信息被整合在一起。这项研究展示了在单神经元分辨率下,运动神经元如何通过与其他神经元的相互作用来帮助形成威胁-奖励选择行为。运动神经元通常被认为是来自其他神经元的命令的被动接受者。然而,这项研究表明,运动神经元可能通过调节运动前神经元来塑造运动行为,运动前神经元起到整合感觉神经元和运动神经元的信息的作用。
Proper threat-reward decision-making is critical to animal survival. Emerging evidence indicates that the motor system may participate in decision-making but the neural circuit and molecular bases for these functions are little known. We found in C. elegans that GABAergic motor neurons (D-MNs) bias toward the reward behavior in threat-reward decision-making by retrogradely inhibiting a pair of premotor command interneurons, AVA, that control cholinergic motor neurons in the avoidance neural circuit. This function of D-MNs is mediated by a specific ionotropic GABA receptor (UNC-49) in AVA, and depends on electrical coupling between the two AVA interneurons. Our results suggest that AVA are hub neurons where sensory inputs from threat and reward sensory modalities and motor information from D-MNs are integrated. This study demonstrates at single-neuron resolution how motor neurons may help shape threat-reward choice behaviors through interacting with other neurons. Motor neurons are generally considered to be passive receivers of commands from other neurons. However, this study shows that motor neurons may shape locomotor behaviour by regulating premotor neurons, and that premotor neurons serve to integrate information from sensory neurons and motor neurons.
