  • Values reported are means ± SD for nine different experiments. InterSDE frequency, The frequency of the periodicities of occurrence of short-duration ictiform events (SDEs); IntraSDE frequency, the frequency of population spike occurrence within SDEs; field spike duration and amplitude, the duration (across baseline) and amplitude (baseline to peak) of population spikes within an SDE.
