Abstract
Corollary discharge allows organisms to discriminate external sensory inputs from self-generated cues. However, the underlying synaptic and molecular mechanisms are not well understood. A new study has identified a tyraminergic corollary discharge signal that extrasynaptically modulates chemosensory neurons in Caenorhabditis elegans.
摘要
侧支放电使生物体能够区分外部感觉输入和自身产生的线索。然而，其潜在的突触和分子机制尚不清楚。一项新的研究已经确定了一种酪胺能侧支放电信号，该信号可以在 Caenorhabditis elegans 的化学感觉神经元的突触外调节。
