Research on event related potential in epilepsy
Objective:To explore the clinical meaning of event related potentials(N400)in epilepsy.Methods:From Jan 2003 to Jan 2007,33 normal people as control group and 30 epilepsy patients in study group were detected by ME-9104k evoked potential detector,and then contrasted and analyzed respectively.Results:At different stages,average wave crest latent period of N400 in study group was longer than that of control group during pretherapy and on therapy(P0.05),but no significant difference in the thirtieth day(P0.05).While average amplitude of wave N400 in the study group was significantly shorter than that of control group during different stage of treatment(P0.05).Conclusion:Event related potentials(N400)could provide objective and effective laboratory data in the diagnosis of epilepsy.
1 Summary For Case Western Reserve University’s debut participation in TREC, we chose to participate in the Enterprise Track expert search task. Our motivation for participation stems from our work developing expert search capability for our prototype vertical digital library, MEMS World Online 1 . Our work incorporates two unique aspects. First, our relevance ranking mechanism relies on term position within each document rather than the number of term occurrences. This mechanism takes into account both term document rank and term co-occurrence proximity. Second, the expert score of closely related colleagues has a small eect on the score of each related expert. This follows the intuition that experts on a particular topic within a single organization tend to closely collaborate with one another. We also make some use of WordNet synonyms. We submitted a total of three runs to this years expert search task.
