EEG activity over the frontal and parietal regions are thought to map onto the seizure pathway in JME. Epileptiform discharges that are not accompanied by obvious clinical events are cautiously termed âsub-clinicalâ and include spike, spike-wave, polyspike-wave and sharp wave discharges. TCIâs are thought to be limited to the actual period in which the sub-clinical discharge occurred without any âpre- or post-dischargeâ effects. The extent of cognitive impairment during such discharges varies according to the type of discharge and its localisation, with the number of spike components and the involvement of fronto-central regions being very important.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information.The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
