CB is also stimulated by nematocytes and basal disk activity. CB then autostimulates itself through Hym-357 ... We used calcium imaging to monitor the activity of RP1 neurons. …
WebMay 1, 2009 · Abstract. Different global patterns of brain activity are associated with distinct arousal and behavioral states of an animal, but how the brain rapidly switches between different states remains unclear. We here report that repetitive high-frequency burst spiking of a single rat cortical neuron could trigger a switch between the cortical states ...
