People have different levels of success in learning new languages, but what are the neuroanatomical factors related to differences in language learning ability?

The advantage of using ultra-high field MRI for this study is that it improves the signal-to-noise ratio and continuous tissue contrast, allows high resolution, limits partial volume effects, and produces more effective tissue segmentation from the T1-weighted image volume
The advantage of using ultra-high field MRI for this study is that it improves the signal-to-noise ratio and continuous tissue contrast, allows high resolution, limits partial volume effects, and produces more effective tissue segmentation from the T1-weighted image volume
The study used ultra-high field (7T) magnetic resonance imaging to estimate cortical thickness and surface area from sub-millimeter resolution image volume

There is a correlation between the surface area of the left posterior lower precuneus cortex and the vocabulary learning ability, which may indicate a greater tendency for vocabulary-graphic association
Using eICV and age as covariates, the Vocabulary Learning Ability Propensity Score (LLAMA B) is related to the surface area of the left posteromedial cortex covering the lower left posterior wedge

Speech memory tendency (LLAMA D) is related to left arcuate tract (AF) axial kurtosis (AK) and left upper longitudinal tract (III) axial kurtosis (AK)
Speech memory tendency (LLAMA D) is related to left arcuate tract (AF) axial kurtosis (AK) and left upper longitudinal tract (III) axial kurtosis (AK)
In addition, there is a negative correlation between the voice memory score and axial kurtosis of the left arcuate tract and the average kurtosis, axial kurtosis, and radial kurtosis of the upper left longitudinal tract III, which connect the cortex that is important for voice working memory The bundle of regions
In conclusion, the results of this study indicate that the larger cortical surface of the left posterior medial group is beneficial to the cultivation of vocabulary learning ability, which may reflect the greater declarative memory storage capacity of language-related vocabulary-graphic associations
