Magnetoencephalography was applied to subjects who imagined themselves hurdling in self-centered space. In three of six subjects all 300 trials in the motor imagery condition revealed the precuneus dipole. When we divided the 300 trials into four overlapping blocks (one block = 150 trials), all six subjects showed precuneus activity. The latency of the(More)
The pharmacokinetics of aniracetam (AP) and its main metabolites, 4-p-anisamidobutyric acid (ABA), 2-pyrrolidinone (PD) and p-anisic acid (AA), in 3 brain regions (cerebral cortex, hippocampus and thalamus) was investigated after single intravenous (i.v.) and oral administrations of AP to rats. AP, AA and PD were rapidly distributed into the 3 brain regions(More)
We investigated the inhibition mechanism of lipid peroxidation by estrogens. Estradiol and 2-hydroxyestradiol showed strong inhibitory activities toward NADPH and ADP-Fe(3+)-dependent lipid peroxidations in the microsomes from rat livers only when the steroids were added to the reaction system before the start of the peroxidation reaction. These steroids(More)
