Tsinghua University team develops a 1-gram wireless microscope to record brain activity in freely moving miceMachine translation

The fingernail-sized microscope can be mounted on a mouse’s head to observe natural behavior without a tether. The team says it achieves single-cell resolution across a 6 mm field of view and simultaneously recorded more than 8,500 neurons in 14 cortical regions of one mouse. In tests, measures of movement showed no significant difference between mice wearing the device and those without it.
