Individual differences in second language (L2) aptitude have been assumed to depend upon a variety of cognitive and personality factors. Especially, the cognitive factor phonological working memory has been conceptualised as language learning device. However, strong associations between phonological working memory and L2 aptitude have been previously found(More)
There are an increasing number of studies on the localization of personality using voxel-based morphometry. Due to the complex analytic challenge in volumetric studies, the specification and treatment of the nuisance covariate (such as age, gender, and global measures) is currently not consistent. Here, we present a study in which we conducted voxel-based(More)
An unanswered question in adult language learning or late bi and multilingualism is why individuals show marked differences in their ability to imitate foreign accents. While recent research acknowledges that more adults than previously assumed can still acquire a "native" foreign accent, very little is known about the neuro-cognitive correlates of this(More)
The characteristics of the cognitive processing of food, body and emotional information in patients with anorexia nervosa (AN) are debatable. We reviewed functional magnetic resonance imaging studies to assess whether there were consistent neural basis and networks in the studies to date. Searching PubMed, Ovid, Web of Science, The Cochrane Library and(More)
Besides food restriction, hyperactivity is considered a key behavioral trait of anorexia nervosa (AN), playing a major role in the pathogenesis and progression of the disorder. However, the underlying neurophysiology remains poorly understood. We used functional magnetic resonance imaging during two affective go/no-go tasks to probe inhibitory control in(More)
The current study aimed to assess the relationship between the neuropsychiatric symptoms in Alzheimer's disease (AD) and the regional grey matter (GM) volume using voxel based morphometry (VBM). Data of 85 AD patients, 208 subjects with mild cognitive impairment (MCI), and 131 healthy controls were selected from the Alzheimer's Disease Neuroimaging(More)
Phosphorylation of histone H3 (H3) on serine 28 (S28) at genomic regions marked by trimethylation of lysine 27 (H3K27me3) often correlates with increased expression of genes normally repressed by Polycomb group proteins (PcG). We show that amphetamine, an addictive psychostimulant, and haloperidol, a typical antipsychotic drug, increase the phosphorylation(More)
Individuals diagnosed with mild cognitive impairment (MCI) are at high risk of transition to Alzheimer's disease (AD). However, little is known about functional characteristics of the conversion from MCI to AD. Resting-state functional magnetic resonance imaging was performed in 25 AD patients, 31 MCI patients, and 42 well-matched normal controls at(More)
bZIP (basic leucine zipper) transcription factors coordinate plant growth and development and control responses to environmental stimuli. The genome of Chinese cabbage (Brassica rapa) encodes 136 putative bZIP transcription factors. The bZIP transcription factors in Brassica rapa (BrbZIP) are classified into 10 subfamilies. Phylogenetic relationship(More)
Elderly individuals with subjective memory impairment (SMI) report memory decline, but perform within the age-, gender-, and education- adjusted normal range on neuropsychological tests. Longitudinal studies indicate SMI as a risk factor or early sign of Alzheimer's disease (AD). There is increasing evidence from neuroimaging that at the group level,(More)
