Photometry allows brain activity to be observed using fluorophores, with a single optical fibre in animals that are free to move around

➔ Advice prior to purchasing equipment and supplies suited to your experiments.

➔ Installation and testing of your photometry setup.

➔ Synchronization of your photometry equipment with your various behavioural apparatus.
➔ The GCaMP protein (excitation and emission), how to correct for photobleaching.

➔ Understand the different recordings systems and accessories.

➔ Principles of analysis: understanding the isosbestic signal, correcting artifacts, and calculating dF/F.
➔ Introduction to brain surgery and implant placement.

➔ Calcium signal recordings using the principal photometry systems (Doric, RWD, Thorlabs/Hamamatsu).
