2
Imaging system setup
30 minSet up confocal/fluorescence microscope or small-animal MRI parameters and focal plane
💡 Tip Optimize signal-to-noise and frame rate
⚠️ Caution Excess laser causes photodamage

⚠️ 5 Common Beginner Mistakes
- ① Dye quenching/poor loading weakens signal
- ② High laser causes photobleaching/damage
- ③ Motion/drift artifacts interfere
- ④ Focal drift blurs images
- ⑤ Poor stimulus synchronization misreads responses
❓ FAQ
+What does calcium imaging measure?
Calcium imaging monitors population activity reflecting [Ca²⁺] changes from action potentials.
+Confocal vs widefield?
Confocal rejects out-of-focus light with better SNR/resolution; widefield is faster for live populations.
+How to avoid photodamage?
Reduce laser power/exposure, use brighter or low-phototoxic probes.
