WebSep 23, 2024 · Mice were only excluded from behavioral studies if they could not complete the entire experiment due to health concerns, if there was no dynamic photometry signal 3 weeks after surgery, or if the location of the photometry fiber tip was histologically determined to be outside the LNAc (1 mouse). WebJun 23, 2024 · In this study, fiber photometry was used to record changes in astrocyte Ca 2+ concentrations from head-fixed mice, as Y/C ratios (Fig. 1B). We first confirmed whether Y/C ratios calculated from the YFP fluorescence and CFP fluorescence precisely reflect the changes in astrocyte Ca 2+ concentrations under our experimental conditions.
WebPhotometry recordings of OxLight1 in mice show rapid orexin release assocd. with spontaneous running behavior, acute stress and sleep-to-wake transitions in different brain areas. Moreover, two-photon imaging of OxLight1 reveals orexin release in layer 2/3 of the mouse somatosensory cortex during emergence from anesthesia. WebAstrocytic [Cl −] i changes rapidly in response to awakening. To monitor dynamic changes in astrocytic [Cl −] i in awake freely moving or naturally sleeping mice, we used fibre photometry of astrocytes specifically expressing the fluorescent Cl − sensor mClY 37 under the Gfap-promoter to record the bulk signal from many astrocytes. mCIY was delivered via …
WebOptical mice don't take pictures that are saved anywhere. They use two images to compare them to each other and then throw away the old one to make room for the next image. … WebThe limitations of fiber photometry are low cellular and spatial resolution, and the fact that animals must be securely tethered to a rigid fiber bundle, which may impact the …
WebApr 4, 2024 · Mice were habituated to an FED in their home cage for several days before recording. For electrophysiological recordings, mice were fasted for 4–6 h preceding each recording, and mice ate from FED for 2–3 h. For fiber photometry experiments, mice were not fasted but were run overnight, and so were required to eat pellets to obtain sustenance.
