Fig. 1.

A schematic diagram of the model architecture. The small triangles in layer 2/3 and layer 5/6 represent pyramidal neurons, the small open circles in layer 4 are spiny stellate neurons, and the small solid circles in each layer are inhibitory neurons. The arrows show the connection patterns between different layers and the signal flows coming from the other areas. The large solid open circle in each layer represents the lateral excitatory connection radius, the large dashed open circle in each layer represents inhibitory connection radius. The dotted open circles in layer 2/3 and layer 5/6 denote the top-down attention modulation radius
