Abstract

Abstract: Objective To investigate effects of brain activation in the whiter matter during active unilateral limb movement. Methods A functional magnetic resonance imaging study was performed in 21 male subjects in three conditions: active ankle movement on the right side; movement plus concurrent stimulation over the tibialis anterior; and movement plus concurrent stimulation over a control area. SPM8 was used to analyze data. The threshold was set at a familywise error rate correction P<0.01. Results All conditions evoked bilateral activation in the corona radiate. The activation was mainly distributed on the left side. Conclusion Unilateral limb movement can evoke brain activation in the corona radiate on the contralateral side. Such activation may indicate the functional state of neural pathways.

Key words: active movement, white matter activation, magnetic resonance imaging
