Depiction GRIN lens+ miniscope in vivo imaging. Miniscope is head mounted to a baseplate and allows for freely animal movement. A blue LED is triggered and light is reflected by a dichroic mirror into brain via the GRIN lens (see also, Figure 1b). Neurons infected with GCaMP emit green fluorescence while active in response to blue light. Green light (i.e., neural activity) is relayed back through the GRIN lens, past the dichroic mirror towards an imaging sensor and relayed offsite for analysis
