Hemispheric
Function of Japanese Abacus Masters: An Examination by Electroencephalograph
T. Hatta & F. Yamada |
To
examine the hypothesis that the right hemisphere engages more strongly
than the left in mental calculation in abacus masters whereas the
left hemisphere engages more strongly in ordinary people, EEG activities
during mental calculation task and news listening task were measured.
EEG power variations from resting state were analysed as a function
of the frequency bands and brain regions. Parametric analyses did
not necessarily support to the hypothesis while nonparametric results
supported the hypothesis.
