Stimulated and non-stimulated task performance by TBI Status for subjects receiving CA1 stimulation based on MDM and MIMO models. Positive stim = stimulation patterns derived from modeling correct DMS trials (MIMO) or from MDM patterns that were congruent with the content classification of the Sample/Match image. NoStim = trials with no stimulation delivered. Negative stim = trials with random stimulation patterns (MIMO) or from MDM that were not specific to the content classification of the Sample/Match image). Stimulation was only delivered during the Sample phase of DMS trials, and not delivered during Match phase, nor during the DR assessment. %Change = percentage of increase (+, no symbol) or decrease (–) compared to NoStim.
