Demand of the Product：we utilized in vivo fiber photometry to measure calcium (Ca2+) dynamics of LDTGABA neurons in awake behaving mice, during the presentation of diverse sensory stimuli. And we combine optogenetic modulation of excitation/inhibition in LDTGABA neurons with fiber photometry of DA release in NAcLat
