Theoretical prediction of the performance derived from computational simulations of a delayed match-to-sample task with n selective neural assemblies simultaneously stimulated. Performance is calculated by assuming that an item is held in memory when its associated selective pool shows a mean persistent activity νthres ≥ 20 Hz during a period of 2 s after removal of the stimuli. n-1 selective pools are stimulated at λ = 60 Hz and the remaining pool receives a higher stimulation λsal that emulates visual saliency. λsal = 60 Hz (no saliency), 70 Hz, 80 Hz, 100 Hz, 150 Hz and 200 Hz. The results are derived from computational simulations of a biologically plausible network of spiking neurons [3].
