Also, we compared the relationships between cognitive function and CNV resolution, cognitive function and P300. The correlation of the data of CNV, CNV resolution, and P300 and the scores on 4 psychological tests; The Wisconsin Card Sorting Test (WCST), number repetition, visual memory test, and block design for 15 subjects whose ages ranged from 7 to 24 years were examined. The results shows that there were significant correlations between P300 latency at Cz and auditory short-term memory, visual conceptual abilities, and executive function. There were also significant correlations between P300 latency at Pz and visual conceptual abilities and executive function. There were no correlations between CNV amplitude and CNV resolution and all psychological test data. We suggested that CNV resolution is not a good measure for evaluation of brain function reflecting cognitive development., 長崎大学医学部保健学科紀要 = Bulletin of Nagasaki University School of Health Sciences. 2003, 16(2), p.97-102}, pages = {97--102}, title = {随伴性陰性変動(CNV)解消課程の発達的変化と4種の認知検査のスコアとの関係}, volume = {16}, year = {2003} }
