    Abstract

    Tetanic stimulation was applied to affect network connectivity, as assessed by conditional firing probabilities. We showed that the first period(s) of titanic stimulation at a certain electrode significantly alters functional connectivity, but subsequent, identical stimuli do not. These findings support the hypothesis that isolated networks develop a new balance that supports the activity patterns in response to the stimulus. Accordingly, subsequent stimuli no longer disturb the equilibrium. Similar results were obtained with slow pulses (-0.2 Hz) instead of tetani, suggesting that connectivity changes are driven by network activation, rather than the tetanus itself.
