英文摘要
We presented a scenario on the possible mechanism of cortical state transitions which occur associated with the arrival of top-down attention (s). This study would provide the basic framework for mathematical study and modeling of such cortical state transitions. We argue how the three physiological mechanisms including the corticopetal acetylcholine induce transient reconstruction of attractors, which simultaneously work in the layer 1 and 2/3 with top-down attentional glutamatergic spike volleys.
