Bioluminescence imaging in vivo. Lentivirus carrying synapsin-LMO1 (Gluc-ChR2-EYFP) was injected into the right premotor cortex of a mouse. A month later mice were imaged in vivo after intravenous injection of CTZ (luminescence), then perfused and brain-sectioned for fluorescence imaging (fluorescence)
