Comparison of two methods of analysis on hand motor functional MRI: statistical method and independent component analysis

摘要

Here we analyze two methods to analysis on the hand motor functional MRI of human. Statistical methods especially correlation method is considered as golden standard for assessing where is the region with some statistical confidence. But dependence on the fixed reference function can be source of error and inflexibility to estimate variable HRF(hemodynamic response function). So we implemented the ICA as a data-driven methods free from prior knowledge and constraints. We found that both of results are almost same in the sense of prior anatomical knowledge about activation site of motor function.
