| 摘 要： | 本文对157例胎儿和新生儿脑的颞平面进行了定量分析和动态学观察。结果如下:1.82%的胎儿和76%的新生儿脑的左侧颞平面大于右侧;2.各胎龄组的胎儿和新生儿脑的左侧颞平面的平均值明显大于右侧;3.最早出现颞平面的胎龄是胚胎6个月;4.各胎龄组中左侧颞平面的出现率大于右侧;5.随着胚胎发育,颞平面的左右比率增大。上述结果表明,颞平面的左右不对称在颞平面出现时就存在,而且随着胚胎发育而变化。

| Abstract: | Quantitative analysis of and developmental observation on the planum temporale of 157 fetuses and infants have been made. The results are as follows: 1. Left planum temporale of 82% fetal brains and 76% infant brains is larger than the right. 2. The average area values of the left planum temporale in infants and various groups of fetuses are larger statistically than those of the right. 3. The earliest age when the planum temporale can be seen is the sixth gestational month. 4. Rate of the appearance of the left planum temporale in fetuses is larger than that of the right. 5. Right/left ratio of planum temporale increases as the fetus develops. The above results show that the asymmetry of the left and right planum temporale is present since the planum temporale appears, and changes as the fetus develops. |
