Optical imaging of intrinsic signals

WebJan 1, 2024 · Voltage-sensitive dye imaging is an experimental technique to measure neuronal network activity from in vivo brains or live brain slices. In this technique, exogenous chemical agents are employed to continuously and rapidly transduce changes in cell membrane potential into changes in fluorescence emission. Intrinsic optical imaging … WebNov 10, 2024 · Optical imaging of intrinsic signals was performed to map the layout of functional modules, so-called orientation domains, in the visual cortex. Briefly, craniotomy was made above the primary visual cortex, and a Teflon-chamber was implanted using bone screws and dental cement.
