Photometry mice
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. 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.
