共有35名受过大学教育的正常男性（24名右手书写者和11名左手书写者）和36名年龄和教育程度匹配的女性（25名右手书写者和11名左手书写者）接受了7个8 cm（3）体素的质子磁共振波谱检查，包括左右额叶尖端、左右颞叶中部、左右丘脑和下丘脑。依赖性指标为N-乙酰天冬氨酸（NAA）、含胆碱化合物（Cho）和肌酸/磷酸肌酸（Cr）代谢产物相对于总H2O的峰面积比。正如预期的那样，丘脑灰质比端脑体素（包含白色和灰质）含有更高的NAA比率（p
A total of 35 university-educated normal men (24 right handwriters and 11 left handwriters) and 36 age- and education-matched women (25 right handwriters and 11 left handwriters) underwent a proton magnetic resonance spectroscopy examination in seven 8 cm(3) voxels including the right and left frontal lobe tips, the right and left mid-temporal lobes, the right and left thalami, and the hypothalamus. Dependent measures were N-acetylaspartate (NAA), choline-containing compounds (Cho) and creatine/phosphocreatine (Cr) metabolite peak area ratios relative to total H2O. As expected, thalamic grey matter contained higher NAA ratios than telencephalic voxels (containing white and grey matter) (p
