We hypothesized that the changes in blood flow of the finger during concentrated finger perception reflect cerebral cortex activation. To identify this hypothesis, we measured finger skin blood flow (FSBF) and cerebral blood oxygenation (CBO2) in prefrontal cortical areas during Braille reading performed under the blind condition. FSBF was decreased during Braille reading (decreased by -32%). On the other hand, CBO2 was increased during Braille reading (increased by 2%). These responses to the discrimination task were also observed in elderly peoples. Moreover, a significant relationship was observed between the changes in FSBF and CBO2 (r = -0.42). The responses in FSBF and CBO2 became gradually fast by leaning effect evoked by repeated tests. These findings suggest that the modulation of finger skin blood flow during a tactile discrimination task is related to cerebrocortical activity.

我们假设集中手指感知期间手指血流的变化反映了大脑皮层的激活。为了验证这一假设，我们在盲文阅读盲文时测量了前额皮质区域的手指皮肤血流量（FSBF）和脑血氧饱和度（CBO2）。盲文阅读期间 FSBF 降低（降低-32%）。另一方面，CBO2在盲文阅读期间增加（增加2%）。在老年人中也观察到了对歧视任务的这些反应。此外，观察到 FSBF 和 CBO2 的变化之间存在显着关系 (r = -0.42)。由于反复测试引起的倾斜效应，FSBF和CBO2的反应逐渐变快。这些发现表明，触觉辨别任务期间手指皮肤血流的调节与大脑皮质活动有关。
