@ShanTan See this thread: > [@Has anyone tried conditioned place aversion (CPA) with pain?](https://forum.painresearcher.net/t/has-anyone-tried-conditioned-place-aversion-cpa-with-pain/347): > > I saw this CPA assay in a paper from Cheng et al. (2017) [https://www.nature.com/articles/nn.4549](https://www.nature.com/articles/nn.4549) [07 PM] This looks laborious but useful. To measure the negative valence effect associated with brush-evoked dynamic mechanical hypersensitivity, we used a biased compartment-assignment proce- dure, in which we measured the influence of VT3Lbx1 neurons on the time of mice spending in the dark compartment receiving conditional stimulations. The CPA apparatus consisted of two chambers (10 × 10 × 1… --- _[View the full topic](https://forum.painresearcher.net/t/best-supraspinal-nociceptive-assays/656)._
