Feature-based attention simulations with different proportions of second layer neurons receiving top-down modulation, as indicated above each plot.

A. Example trials from the attention task for each proportion. B. Response functions when the stimulus was attended (solid lines) and unattended (dotted lines). Each line color represents a different level of feature-based attention modulation strength....
