Automated detection of blink reflexes evoked by optogenetic stimulation of TRPV1-expressing corneal nociceptors in transgenic mice
This study presents a novel, automated behavioral paradigm that utilizes cell-type-specific optogenetic stimulation of TRPV1-expressing corneal nociceptors combined with DeepLabCut-based machine learning to achieve high-accuracy, observer-independent detection of blink reflexes in transgenic mice, offering a precise alternative to conventional air puff methods for studying corneal pain.
