Effects of Specificity of MIMO-derived stimulation as a function of type of DMS trial. Performance levels averaged over all animals are shown for both Object (left) and Spatial (right) trials with respect to intervening delay (upper) and #images (lower). Performance facilitation on MIMO Scrambled Stim trials was not above that on No Stim trials. On Scrambled Stim trials patterns in which MIMO coefficients were randomized with respect to neuron and time had little or no effect and did not disrupt normal performance. Since only MIMO Strong code patterns were used to generate the Scrambled Stim patterns, they were not functionally equivalent to the weak code patterns shown in Figure 8. *p<0.01, **p<0.001 Stim vs. No Stim.
