An inhibitory acetylcholine receptor gates context dependent mechanosensory processing in<i>C. elegans</i>
SUMMARY An animal’s current behavior influences its response to sensory stimuli, but the molecular and circuit-level mechanisms of this context-dependent decision-making is not well understood. In the nematodeC. elegans, inhibitory feedback from turning associated neurons alter downstream mechanosensory processing to gate the animal’s response to stimuli depending on whether the animal is turning or moving forward [1–3]. Until now, the specific neurons and receptors that mediate this inhibitory feedback were not known. We use genetic manipulations, single-cell rescue experiments and high-throughput closed-loop optogenetic perturbations during behavior to reveal the specific neuron and receptor responsible for receiving inhibition and altering sensorimotor processing. An inhibitory acetylcholine gated chloride channel comprised oflgc-47andacc-1expressed in neuron RIM receives inhibitory signals from turning neurons and performs the gating that disrupts the worm’s mechanosensory evoked reversal response..
