【摘要】 利用组织方法及微机处理技术测量了秋季成年雌、雄鸣禽黄胸巫鸟（ Ｅｍ ｂｅｒｉｚａ ａｕｒｅｏｌａ）发声相关核团 Ｈ Ｖｃ、 Ｒ Ａ、 Ｘ 区、ｎⅩⅡｔｓ 以及与发声无关的核团（ Ｓｐ Ｍ）的体积．结果表明：前脑的发声相关核团 Ｈ Ｖｃ、 Ｒ Ａ 及 Ｘ区具有明显的雌雄差异，而延髓的ｎⅩⅡｔｓ 以及与发声无关的核团 Ｓｐ Ｍ 则差异不明显更多还原

【Abstract】 The volumes of nuclei involve in vocal control or song learning(HVc,high vocal center;RA,nucleus robustus archiastriatalis;X areas;nⅩⅡts,nucleus tracheosyringealis)are observed and measured Emberiza aureola. The result shows that there are significant sexual difference for the volumes of HVc,RA and X area,but the difference is not significant for nⅩⅡts.更多还原
