Protocol for recording the discharge of locus coeruleus neurons in free-moving mice during different sleep-wake stages

Abstract

Summary: Cortical electroencephalography (EEG) is generally used to detect the different sleep-wake states of animals. EEG combined with in vivo multichannel recording provides a powerful tool for decoding the neural network of sleep-wake regulation. Here, we detail a protocol using cortical EEG combined with in vivo multichannel recording to examine the activity of locus coeruleus (LC) neurons in free-moving mice at different sleep-wake stages. The procedures for electrode fabrication, the surgery to implant electrodes, and post-recording data analysis are also included.For complete details on the use and execution of this protocol, please refer to Liang et al. (2021).
