Protocol for an open-source system to integrate calcium imaging, pupillometry, and locomotion-estimated tracking in head-fixed mice
Abstract
Summary: A wide selection of behavioral assays in systems neuroscience relies on head-fixation protocols to integrate in vivo multi-photon imaging approaches. For this, simultaneous pupillometry and locomotion tracking in head-fixed mice are used to measure behavioral responses and identify neural correlates. Here, we present an open-source protocol for assembling a complete head-fixation system that integrates pupillometry and locomotion-estimated tracking with multi-photon calcium imaging. We include detailed procedures for head-fixation and for data collection. : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
