为探究手语学习过程中大脑神经变化,利物浦大学等研究人员利用 fMRI 和 DTI 技术,对 26 名健康志愿者进行研究。结果显示,短期手语训练后,参与者行为表现提升,大脑功能和微观结构改变。该研究为理解手语学习神经机制提供依据。 在人们的认知里,语言通常意味着有声的交流,但手语作为一种独特的交流方式,有着别样的魅力。...
Imaging using DTI showed that there were significant decreases in all diffusivity measures (MD, RD and AD) within the left angular gyrus post-learning. Notably, behavioural improvements were significantly correlated with DTI measures, mostly MD and RD. This provides strong evidence that the observed ...
Acute strokePrognosisWhite matter tractsCerebrovascular stroke is one of the leading causes of death worldwide. Imaging with conventional MR techniques cannot provide reliable information as regard the integrity of the white matter tracts and therefore limiting its ability to predict the clinical outcome....
Diffusion Magnetic Resonance Microscopy (MRM) provides near-microscopic resolution without relying on a sample's optical transparency for image formation. Diffusion MRM is a noninvasive imaging technique for quantitative analysis of intrinsic features of tissues. Thus, we propose using Diffusion MRM to ...
