Memory function, intelligence, and depression were measured by using the Mini-Mental State Examination, the revised Wechsler Adult Intelligence Scale and the Self-Rating Depression Scale, respectively. P300 latency was measured during silent-count and button-press tests at three midline scalp (Fz, Cz, and Pz) sites for all subjects by using an auditory ‘odd-ball’ paradigm. Neuropsychological memory score was predicted by intelligence score, but neurophysiological P300 latency was predicted by memory score for the silent-count test and by intelligence score for the button-press test. These results show that the P300 event-related potential component is sensitive to the diverse nature of cognitive deficits in post-traumatic brain injury patients during different types of discrimination tasks. However, future research is necessary to replicate and extend these findings.Elsevier LtdJournal Articleapplication/pdfhttp://hdl.handle.net/2115/17120https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/17120/1/JCN13-9.pdf0967-5868Journal of Clinical Neuroscience1399179222006-11enginfo:pmid/17049245info:doi/10.1016/j.jocn.2004.11.026author
