A factor analysis of the rat''s corpus callosum 总被引:1,自引:0,他引:1
Previous work from our laboratory (Berrebi et al., Brain Research, 438 (1988) 216-224) demonstrated region-specific sexual dimorphisms in the size of the rat's corpus callosum, which are modifiable by extra stimulation in early life. These differences are assumed to reflect regional corticocortical fibers of passage which are altered differentially by gender and our experimental manipulations. In this paper, we report our findings when the original data are reanalyzed using a newly developed computer program. This program not only reproduced, with very high accuracy, the original means, but also permitted us to examine computer generated callosal width scores via a factor analysis procedure. Such a procedure yields useful information concerning the clustering of callosal fibers and thus contributes significantly to our hypothesis that discrete cortical regions are selectively sensitive to experimental variables. Factor analyses of the callosal variables and brain weight of 155 rats found 7 width factors, and an eighth factor which contained the variables of brain weight, callosal length, and callosal perimeter. Callosal area did not load significantly on any of these factors. The percentile locations of the width factors, starting at the anterior (genu) end were: widths 1-5, 6-17, 24-38, 46-57, 62-72, 79-95 and 96-99. Use of these factor scores in analyses of variance revealed that the male callosum is wider than the female's, with the differences most pronounced in the genu and the most posterior portion of the splenium. Both age and early handling experience influenced the callosal width factors.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

The activity of glycogen phosphorylase, the enzyme that controls glycogen breakdown, was histochemically mapped in the olfactory bulbs of 19-day-old rats. The effect of early odor experience on subsequent olfactory bulb phosphorylase activity was also examined. The highest level of phosphorylase staining in the bulb (and seemingly the highest in the brain) was in the glomerular layer, followed by the external plexiform, internal plexiform, granule cell, and olfactory nerve layers. Virtually no activity was visible in the large output neurons of the bulb, mitral, and tufted cells. Early peppermint odor experience, previously shown to increase metabolic activity in specific glomerular foci as measured by 2-deoxyglucose uptake, had no apparent effect on glomerular-layer phosphorylase activity. In some odor-familiar animals, however, patches of activity were seen in the internal plexiform layer in the area of the bulb where foci of high deoxyglucose uptake are seen in response to peppermint. The patches were directly in line with modified glomerular clusters often seen to underlie foci of enhanced deoxyglucose uptake. The existence of particularly heavy activity in the peripheral third of the glomerular layer, where glycogen-containing modified Schwann cells have been localized, raises the possibility that the glomerular-layer activity is at least partially glial in origin. Finally, because of its rich noradrenaline and serotonin innervation and high density of insulin receptors, the olfactory bulb is proposed as a model system to study the interaction of glycogen/glucose metabolism with neural activity in a relatively well-defined neuronal circuit. 相似文献

目的:评价制白附子70%乙醇提取物的急性毒性作用。方法:灌胃给予大鼠25.0g/kg、50.0g/kg、100.0g/kg制白附子70%乙醇提取物1次,测定d1(给药当天)、d2、d3、d7、d14大鼠体重及给药前、给药后4h~28h、28~52h的饲料消耗量,计算摄食量,并于d3和d14各处死50%动物进行尸体解剖、血液生化学检查和血液细胞学检查。结果:给药第3d,低剂量组大鼠脾脏、胸腺系数增大(1.25±0.40,0.27±0.06),高、低剂量组血清CREA含量下降(45.4±6.12μmol/L,41.7±21.4μmol/L),高剂量组血清CK含量上升(2068.3±877.8IU/L),以上数据与对照组比较均有统计学差异。给药14d,低、中剂量组血清CREA含量升高(70.6±15.6μmol/L,67.8±8.10μmol/L)。未观察到对大鼠体重、摄食量及血液细胞学指标有所影响。结论:制白附子70%乙醇提取物的三个受试剂量对大鼠急性毒性作用不明显。 相似文献
