Abstract

Three-dimensional images of nuclei facilitate morphological comparisons between differing animal groups. As revealed by computer-assisted techniques, the greater volume in male rats of the sexually dimorphic nucleus of the preoptic area was not proportional in all directions. The nucleus was more elongated in males than females, indicating a sex-dependent shape. This study also indicated that the volume of the suprachiasmatic nucleus was larger in males.

摘要

细胞核的三维图像有助于对不同动物群体进行形态学比较。计算机辅助技术显示，雄性大鼠视前区性二态核的体积更大，但并非在所有方向上都成比例。该核在雄性中比雌性更长，表明存在性别依赖性形状。这项研究还表明，雄性大鼠的视交叉上核体积更大。
