Numerous cross-sectional and observational longitudinal studies show associations between expertise and regional brain anatomy. However, since these designs confound training with genetic predisposition, the causal role of training remains unclear. Here, we use a discordant monozygotic identical twin design to study expertise-dependent effects on neuroanatomy using musical training as model behavior, while essentially controlling for genetic factors and shared environment of upbringing.

From a larger cohort of monozygotic twins, we were able to recruit 18 individuals 9 pairs that were highly discordant for piano practice. The analyses revealed that the musically active twins had greater cortical thickness in the auditory-motor network of the left hemisphere and more developed white matter microstructure in relevant tracts in both hemispheres and the corpus callosum.

These findings provide the first clear support for that a significant portion of the differences in brain anatomy between experts and nonexperts how do correlation and causation differ on causal effects of training. Many neuroimaging define dogfooding software have documented that experts in various domains differ from nonexperts in regional brain anatomy Ullén et al.

Several of these studies have used musicians as a model group, finding larger volume and cortical thickness of auditory and motor regions, the cerebellum, as well as white-matter structural differences, for example, of the corticospinal tract which carries motor responses from the cortex to the spinal cord, and the corpus callosum which connects the cerebral hemispheres Schlaug, Jäncke, Huang and Steinmetz ; Schlaug, Jäncke, Huang, Staiger, et al.

Thus, a common assumption is that similar outcomes reflect causal effects of training on brain plasticity. Furthermore, twin modeling studies demonstrate that both practice itself and its correlation with expertise-related outcomes can be heavily influenced by genetic factors Mosing, Madison, et al. Hence, expertise likely depends on many variables Ullén et al. This has important implications for how we interpret previous neuroimaging studies, which have typically relied on cross-sectional and observational longitudinal designs with self-selected samples Moreno and Bidelmanthat is, designs where genetic predispositions can influence group compositions and outcomes.

Moreover, since no longitudinal study have come close to providing the training required to become an expert, it is unclear how such results correspond to research on professionals. Gray matter in the primary motor cortex, for example, does not expand linearly with practice of fine motor skills, but renormalizes after an initial growth period, which means that the observed volume increases in experts may not show a simple relation to practice per se Wenger et al.

A critical question is thus to what extent the neuroanatomical differences between experts and nonexperts depend on training or on genetic constitution. We address this question in a novel way using a monozygotic cotwin control design. Monozygotic twin pairs who are discordant for exposure can be used to approximate a true experiment when experimental approaches are unfeasible McGue et al.

In the case of musical expertise, a randomized controlled trial would have to extend for many years or decades and involve several thousands of hours of practice. Here, since the twins have a common genotype and have shared a common early rearing environment, we can implicitly use the nonplaying twin to estimate what the playing twin would have looked like if he or she had not practiced. Hence, if musical practice has a long-term causal influence on brain structure, we expect that the playing twins will show higher rates of the outcomes described below than their nonplaying cotwins.

From a large cohort of twins Mosing, Madison, et al. Our aim was to use structural and diffusion magnetic resonance imaging to analyze within-pair differences in cortical thickness, cerebellar regional volumes and beyond reasonable doubt meaning in tagalog microstructure fractional anisotropy; FA while effectively controlling for genes and shared environment of upbringing.

We wanted to target the auditory-motor network involved in piano performance, in which neural adaptations are well-replicated. White-matter tracts of interest were the arcuate fasciculus, inferior longitudinal fasciculus and uncinate fasciculus, that is, tracts through which information from the temporal auditory regions can reach the inferior frontal cortex, directly or indirectly Schlaug, Jäncke, Huang, Staiger et al.

The recruitment of participants is described in Eriksson et al. From a cohort of 10 twins monozygotic twins who had participated in an extensive web survey Mosing, Madison, et al. Out of this sample, how do correlation and causation differ twin pairs agreed to participate and come to Stockholm for interviews and testing Eriksson et al. However, due to a scanner malfunction, diffusion-weighted imaging data could not be obtained from one individual excluding one pair from the FA analysis. We chose to focus on keyboard instrumentalists because keyboard is a common instrument type which has been used frequently in the past.

We also wanted to avoid pooling expertise on different musical instruments, for which the behavior and neural implementation could differ substantially Bangert and Schlaug The neuroanatomical images were examined by a neuroradiologist, without remark. The interviews explored nongenetic influences on musical engagement and were organized into 5 sections— 1 perceived reasons for the discordance; 2 childhood differences in specific music related how do correlation and causation differ 3 strong memories of music; 4 the perceived meaning of music in life and for health; and 5 language interests—and analyzed using response categorization.

Relevant results from these interviews are summarized in the Discussion ; further details can be found in Eriksson et al. Travel expenses were covered and the participants were in addition given SEK in reimbursement. The original web-survey Mosing, Madison, et al. This data consisted of self-reports on starting and when applicable ending year of practice, as well as the average number of hours spent on music practice per week in 4 age periods ages 0—5, 6—11, 12—17, and 18—present.

Based on these responses, we calculated hours of early practice ages 0—11 and how do correlation and causation differ total hours of practice. During the scanning sessions, a separate experiment in which we collected functional MRI fMRI data was also conducted to be presented elsewhere. In the present study, we made use of a subset of that data in order to get functional localizers of the cortical ROIs see Cortical Thickness Analysis.

All imaging parameters can be found in the Supplementary material. A brief description of the FreeSurfer preprocessing pipeline can be found in the Supplementary material. The T2w-images were included during preprocessing to optimize refinement of pial surfaces. SPT, involved in auditory-motor transformations Hickok et al. ITG, which plays a role in integrating visual and auditory sensory information e.

PMD, involved in planning and organization of movement sequences Gaser and Schlaug ; Bailey et al. PMV, involved in auditory-motor transformations, for example, associating auditory stimuli with corresponding actions Lahav et al. IFG, which plays an essential role in processing musical syntax and semantics as well as more generally—implicit memory retrieval, audio-motor transformations and serial production rules Sluming et al.

These regions align well with the dorsal and ventral pathways that enable auditory-motor integration in language Saur et al. Consequently, we decided to examine the identified network of brain regions in each hemisphere separately. In brief, during one condition of the fMRI experiment out of severalthe participants used their right hand to improvise simple melodies free ordinal and temporal structureusing a 4-button response box and piano tones as auditory feedback middle How do correlation and causation differ, D, E, F.

Contrasting free how do correlation and causation differ to implicit rest using a second-level one-sample t -test, provided a way of localizing relevant clusters of activity. Only the musician twins were used in this analysis since the main hypothesis concerned the structure of regions that musicians use during musical performance. Since the free improvisation was performed using the right hand only, the left hemisphere ROI labels were transformed to the right hemisphere.

Lastly, using the inverse subject-to-fsaverage registration parameters, all labels could be transformed to native space and cortical thickness values for each label and participant could be calculated. A ROIs used in the cortical thickness analysis, illustrated on the left hemispheric surface of the fsaverage inflated brain. B The tracts of interest shown in the left hemisphere, and corpus callosumbased on probabilistic fiber tracking and generation of streamlines in template space.

The within-pair difference between playing and nonplaying twins in cortical thickness in the auditory-motor network was analyzed using a linear mixed model implemented in R package lmertestwhere cortical thickness was regressed on musicianship. This approach was adopted to test whether there was, in line with our alternative hypothesis, an overall effect of musical training on brain regions central to auditory and motor processing during musical performance. The mixed model allows for estimating a group effect of musicianship on cortical thickness across ROIs, based on within-pair comparisons.

Thus, ROI was included as a fixed effect and pair membership was included as a random effect. As the auditory-motor network is lateralized to some degree, we produced one model for each hemisphere. The model was estimated using restricted maximum likelihood REML and the number of degrees of freedom was calculated using Satterthwaite approximations. Moreover, we correlated the within-pair differences in mean cortical thickness across the network in each hemisphere with the within-pair differences in self-reported music practice one correlation with total hours of training and one correlation with early practice, age 6— The correlation with early practice was added because it is suggested that early practice plays a particular role for brain plasticity Bengtsson et al.

Finally, we calculated the within-pair correlation in mean cortical thickness in each hemisphere based on values extracted using Meaning of punjab in urdu and the full DKT atlas. Diffusion data could not be obtained from one participant due to technical difficulties during scanning.

The FA analysis was consequently limited to 16 individuals i. The preprocessing pipeline can be found in the Supplementary material. A group-specific unbiased FOD template was created Raffelt et al. Upsampled versions of the brain mask images were also registered to the FOD what is gene test in pregnancy and a group brain mask was created based on the intersection of these images.

A group mean FA image was also created. In this analysis, we targeted the key white-matter tracts which enable auditory-motor integration and motor execution and have been identified in previous studies. Thirdly, studies have shown portions of the corpus callosum CC to how do correlation and causation differ larger or more developed in musicians compared with nonmusicians, presumably as a consequence of extensive training of complex bimanual movements and interhemispheric communication Schlaug, Jäncke, Huang, Staiger, et al.

The overall aim of the fiber tractography was to define these tracts of interest and create spatial masks within which to calculate and compare FA between the playing and nonplaying twins. In voxels which contain more than one fiber bundle, it is obviously a nontrivial matter to assign a particular FA value to each fiber bundle. Groeschel and colleagues Groeschel et al.

In superiority name meaning in urdu with predominantly single fiber pathways, there were significant differences in FA between the groups; averaging data over entire tracts obscured these differences and resulted in a loss of sensitivity. Thus, the seed and target regions for the CST, AF, ILF, and UF were defined manually on the what insect is the food chain FA and FOD template images and placed to truncate the tracts before they would greatly spread across an innervated cortical region and mingle with local fibers or greatly cross with other tracts the regions for the CC were defined in a different manner, see below.

This was achieved by 1 creating a seed region at the middle of the tract, 2 performing bidirectional probabilistic fiber tracking, and 3 drawing the final ROIs using the produced streamlines as a reference, in conjunction with the template images. After all ROIs had been defined, unidirectional probabilistic fiber tracking of each tract was performed using default parameters in template space Fig.

The produced streamlines were visually inspected, ROIs were refined and NOT-gates were added where necessary to restrict streamlines from wandering. In this process, we additionally found that changing the FA-cutoff to 0. After examining the produced pathways, the maximum length of produced streamlines was set to 25 mm. This allowed for fiber tracking within the predominantly single-fiber white matter portion of the CC.

All ROIs produced in template space were transformed to the native space of each participant using nearest neighbor interpolation. The transformed ROIs were visually inspected and in the rare case manually edited to ensure accurate anatomical placement typically by extending a NOT-gate to prevent spurious streamlines. Probabilistic streamlines tractography was subsequently performed for each tract and participant using their FOD images and ROI as input.

The following mental causation meaning in philosophy were made to the default parameters in line with the fiber tracking performed in template space see above : the FA-cutoff was set to 0. Tracking was unidirectional and stopped at the final waypoint, except for the CC pathways, for which tracking was bidirectional with a streamline maximum length of 25 mm.

For each produced fiber tract in each participant, a corresponding track density image was created with voxel values equal to the fraction of passing streamlines. An absolute threshold of 0. The FA analysis was performed using the same approach and software as in the cortical thickness analysis see how do correlation and causation differ. The within-pair difference in FA between playing and nonplaying twins was analyzed using a linear mixed model, where FA was regressed on musicianship, while including tracts of interest as a fixed effect and pair membership as a random effect.

Again, this approach was adopted to test whether there was, in line with our alternative hypothesis, an overall effect of musical training on brain regions, in this case white matter regions, central to auditory and motor processing during musical performance. We similarly produced and estimated one model for each hemisphere using REML and Satterthwaite approximations for the degrees of freedom.

Lastly, we correlated the within-pair differences in mean FA in each hemisphere and corpus callosum separately with the within-pair differences in self-reported music practice one correlation what do u mean by food science total hours of training and one how do correlation and causation differ with early practice, age 6— SUIT is a high-resolution atlas template of the human cerebellum how do correlation and causation differ brainstem.

The atlas is spatially unbiased and preserves the anatomical detail of cerebellar structures through a nonlinear atlas-generation algorithm. By using automated nonlinear normalization methods, a more accurate intersubject-alignment can be achieved than with current whole-brain methods.
