The vehicle used to dissolve PF-3628 had no effect on delay-related firing of dlPFC neurons in aged monkeys. A: An example neuron shows that the vehicle (25nA) produced no change in delay-related firing for the neuron’s preferred direction. B: The mean ± SEM firing rate (delay period of preferred direction) of 7 Delay cells, showing the vehicle had no effect on delay-related firing.
