Reaction times. a, Average time to reach the mean activity level after stimulus presentation in the selective pools. A higher gAMPA/gNMDA ratio makes the rates rise faster. The mean activity level is reached fastest for a gAMPA/gNMDA ratio between 0.10 and 0.13. In this range, also the attentional gamma modulation is maximal. b, Time difference in reaching the mean activity level after stimulus presentation between the pools encoding the attended and the unattended stimulus. This difference is biggest for a gAMPA/gNMDA ratio ∼0.12, which is also the range in which attentional gamma modulation is maximal.
