Overview
BLV2.1 and BLV3.0 are neural recording ( ECoG/EMG ) devices designed to help researchers working in neuroscience and especially in the sleep study field. Their compact and light weight design, as well as a long battery life, make them ideal in sleep studies that involve small rodents such as mice. Whilst BLV2.1 supports only ( ECoG/EMG ) recording. BLV3.0 on the other hand, is a closed loop device that has integrated neural recording, temperature measurement, on line sleep-stage scoring and optogenetic stimulation all into one platform.
