a Scheme of in vivo optrode recordings. b Left, spike raster for laser-evoked spikes of a ChR2-tagged neuron. The light pulse was shown in blue (5-ms duration). Right, comparison between light-evoked (blue) and spontaneous (black) spike waveform. c An example of the optogenetically identified LPAGVgat neuron that fired during different predatory phases. d An example of the optogenetically identified LPAGVglut2 neuron that fired during different predatory phases. e PCA and hierarchical clustering dendrogram classified LPAGVgat neurons into three types. The z-score activity plots of 35 LPAGVgat neurons tagged during different predatory phases were shown. f Z-score of firing rates in different predatory phases for each of the three types of LPAGVgat neurons (type I: n = 3; type VI: n = 11; type VII: n = 21 neurons). g PCA and hierarchical clustering dendrogram classified LPAGVglut2 neurons into three clusters. The z-score activity plots of 29 LPAGVglut2 neurons tagged during different predatory phases were shown. h Z-score of firing rates in different predatory phases for each of the three types of LPAGVglut2 neurons (type II: n = 3; type IV: n = 12; type VII: n = 14 neurons).
