Abstract We compared hippocampal volume measures obtained by manual tracing to automatic segmentation with FreeSurfer in 44 younger (20–30 years) and 47 older (60–70 adults, each measured magnetic resonance imaging (MRI) over three successive time points, separated four months. Retest correlations were very high for both segmentations. With FreeSurfer, significantly lower the than age group, which was not case segmentation. Pearson between estimates sufficiently high, numerically even higher...
Evidence for experience-dependent structural brain change in adult humans is accumulating. However, its time course not well understood, as intervention studies typically consist of only 2 imaging sessions (before vs. after training). We acquired up to 18 magnetic resonance images over a 7-week period while 15 right-handed participants practiced left-hand writing and drawing. After 4 weeks, we observed increases gray matter both left right primary motor cortices relative control group; 3...
Increases in striatal activity have been suggested to mediate training-related improvements working-memory ability. We investigated the temporal dynamics of changes task-related brain following training working memory. Participants an experimental group and active control group, trained on easier tasks a constant difficulty shorter sessions than were measured before, after about 1 week, more 50 days training. In initial increase related functionally defined right striatum anatomically left...
Magnetic resonance imaging has become an indispensable tool for studying associations of structural and functional properties the brain with behavior in humans. However, generally recognized standards assessing reporting reliability these techniques are still lacking. Here, we introduce a new approach reliability, termed intra-class effect decomposition (ICED). ICED uses equation modeling data from repeated-measures design to decompose into orthogonal sources measurement error that...
Adequate reliability of measurement is a precondition for investigating individual differences and age-related changes in brain structure. One approach to improve identify control variables that are predictive within-person variance. To this end, we applied both classical statistical methods machine-learning-inspired approaches structural magnetic resonance imaging (sMRI) data six participants aged 24–31 years gathered at 40–50 occasions distributed over 6–8 months from the Day2day study. We...
Most studies of brain structure and function, their relationships to cognitive ability, have relied on inter-individual variability in magnetic resonance (MR) images. Intra-individual is often ignored or implicitly assumed be equivalent the former. Testing this assumption empirically by collecting enough data single individuals cumbersome costly. We collected a dataset multiple MR sequences behavioural covariates quantify characterize intra-individual images for individuals. Eight...
The effects of nature on physical and mental health are an emerging topic in empirical research with increasing influence practical recommendations. Here we set out to investigate the association between spending time outdoors brain structural plasticity conjunctions self-reported affect.We established Day2day study, which includes unprecedented in-depth assessment variability structure a serial sequence 40-50 magnetic resonance imaging (MRI) acquisitions each six young healthy participants...
ABSTRACT The hippocampal formation of the brain plays a crucial role in declarative learning and memory while at same time being particularly susceptible to environmental influences. Education requires well‐functioning hippocampus, but may also influence development this structure. Understanding these bidirectional influences have important implications for educational setting. Here, we provide an overview functions review evidence on how experience shape region its functions, discuss age...
In aging humans, aerobic exercise interventions have been found to be associated with more positive or less negative changes in frontal and temporal brain areas, such as the anterior cingulate cortex (ACC) hippocampus, relative no-exercise control conditions. However, individual measures gray-matter (GM) probability may afford reliable valid conclusions about maintenance losses structural integrity than a latent construct based on multiple indicators. Here, we established factor of GM...
Abstract We investigate the reliability of individual differences four quantities measured by magnetic resonance imaging‐based multiparameter mapping (MPM): magnetization transfer saturation (MT), proton density (PD), longitudinal relaxation rate (R 1 ), and effective transverse 2 *). Four MPM datasets, two on each consecutive days, were acquired in healthy young adults. On Day 1, no repositioning occurred 2, participants repositioned between datasets. Using intraclass correlation effect...
Auditory experience-dependent plasticity is often studied in the domain of musical expertise. Available evidence suggests that years practice are associated with structural and functional changes auditory cortex related brain regions. Resting-state magnetic resonance imaging (MRI) can be used to investigate neural correlates training expertise beyond specific task influences. Here, we compared two groups musicians varying expertise: 24 aspiring professional preparing for their entrance exam...
Playing music relies on several sensory systems and the motor system, poses strong demands control processes, hence, offering an excellent model to study how experience can mold brain structure function. Although most studies neural correlates of expertise rely cross-sectional comparisons, here we compared within-person changes over time in aspiring professionals intensely preparing for entrance exam at a University Arts skilled amateur musicians not exam. In group professionals, observed...
White matter integrity and cognition have been found to decline with advancing adult age. Aerobic exercise may be effective in counteracting these declines. Generally, white has quantified using a volumetric measure (WMV) tensor-based parameters, such as fractional anisotropy (FA) mean diffusivity (MD), the validity of which appears compromised presence crossing fibers. Fixel-based analysis techniques claim overcome this problem by yielding estimates fiber density (FD), cross-section (FC),...
