Abstract

Whisker stimulation in rats was found to increase the local cerebral blood flow (lCBF), its SD and to damp slow oscillations. It was established that lCBF drops slightly within a few seconds after the stimulus onset. The data obtained suggest that lCBF evoked sensory stimulation changes are distinctly localized in different layers of the somatosensory cortex.

摘要

研究发现，对大鼠的触须刺激可增加局部脑血流量（lCBF）、其标准差，并抑制慢波振荡。已证实，刺激开始后的几秒钟内，lCBF会略有下降。所获得的数据表明，由感觉刺激引起的lCBF变化明显定位于体感皮层的不同层。
