摘要：

The neocortex gencrates spontaneous slow oscillations that consist of up and down states during quiescence. Up states are Short epochs of persistent activity that resemble the state of cortical activation during arousal and cognition. The excitability of cortical cells and synaptic networks is impacted by up states. This review describes the characteristics and Putative functional role of up states and their similarity with activated states.
