<i>p</i>-values of locomotor functions versus DA tissue content.

Correlation statistics (p-values derived from Spearman correlation) of locomotor activity measures to respective DA tissue content (total ng or total ng per protein) in striatum and SN analyzed in 7 paired 12- and 30-month old rats. Activity measures are further subdivided into the lifetime average (mean of 17 total locomotor trials conducted at 4 and 12 months for the young group and 22 and 30 months for the old group), session 2 (mean of seven locomotor trials that were conducted at 12 and 30 months), highest and lowest lifetime (highest ever, and lowest ever, locomotor activity measures of the 17 sessions), and last trial (the final locomotor activity measure of the 17, recorded immediately prior to tissue dissection). Significant correlations are in bold.本数据集包含7对12月龄与30月龄配对大鼠的纹状体（striatum）和黑质（Substantia Nigra, SN）中多巴胺（Dopamine, DA）组织含量（以总纳克或每蛋白总纳克为单位）与对应各项运动活动指标的相关性统计结果，相关性的显著性p值由斯皮尔曼相关（Spearman correlation）计算得到。运动活动指标进一步细分为以下四类：1. 终生平均活动量：年轻组（12月龄）于4月龄、12月龄时完成17次运动实验，老年组（30月龄）于22月龄、30月龄时开展该17次实验，取全部17次实验的均值作为终生平均活动量；2. 第2组实验活动量：取12月龄、30月龄时开展的7次运动实验的均值；3. 终生最高与最低活动量：即17次实验中记录到的单次最高、最低运动活动水平；4. 末次实验活动量：即第17次实验的运动活动测量值，于组织解剖前即刻记录。显著相关结果以粗体标注。
