title: Functional connectivity in human auditory networks and the origins of variation in the transmission of musical systems

description: Music producers, whether original composers or performers, vary in their
 ability to acquire and faithfully transmit music. This form of variation
 may serve as a mechanism for the emergence of new traits in musical
 systems. In this study, we aim to investigate whether individual
 differences in the social learning and transmission of music relate to
 intrinsic neural dynamics of auditory processing systems. We combined
 auditory and resting-state functional magnetic resonance imaging (fMRI)
 with an interactive laboratory model of cultural transmission, the
 signaling game, in an experiment with a large cohort of participants
 (N=51). We found that the degree of interhemispheric rs-FC within
 fronto-temporal auditory networks predicts—weeks after scanning—learning,
 transmission, and structural modification of an artificial tone system.
 Our study introduces neuroimaging in cultural transmission research and
 points to specific neural auditory processing mechanisms that constrain
 and drive variation in the cultural transmission and regularization of
 musical systems.
description: Explanation of the data
 and script organization. In the .zip files below you can find
 data and Matlab scripts for the three main experiments and analysis:
 'fMRI' (i.e. fMRI oddball paradigm), rs-fMRI (i.e. resting-state
 functional connectivity), Signaling games, and PPI. A detailed explanation
 of how files are organized can be found in this
 'upd_readme.doc'. For Matlab scripts to work, files must be
 unzipped maintaining the original tree folder structure (see 'Folder
 structure' in readme.doc). suppl_material_fMRI_Analysis_percentagesignalchanges percentage signal change and R script to generate Fig. 3C suppl_material_fMRI_Analysis_secondlevel second-level results from the contrast of interest matlabbatches to pre-process and analyze fMRI oddball data suppl_material_fMRI_Analysis_SPM_matlabbatches.zip suppl_material_fMRI_stimuli_oddballfMRI Auditory stimuli used in the fMRI oddball task suppl_material_rs_fMRI_CONN_batchandData_5mm_sphere_ROIs Regions-of-interest (ROIs) used as seed in the rs-FC analysis suppl_material_rs_fMRI_CONN_batchandData_scripts Batch to run rs-FC preprocessing and analyses, and other scripts suppl_material_rs_fMRI_CONN_batchandData_Data1 rs-FC metadata suppl_material_rs_fMRI_CONN_batchandData_Data2 suppl_material_rs_fMRI_CONN_Results_firstlevel rs-FC results from first-level analysis suppl_material_rs_fMRI_CONN_Results_secondlevel rs-FC results from second-level analysis suppl_material_rs_fMRI_CONN_Results_preprocessing1 rs-FC preprocessing results part 1 suppl_material_rs_fMRI_CONN_Results_preprocessing2 rs-FC preprocessing results part 2 suppl_material_rs_fMRI_CONN_Results_preprocessing3 rs-FC preprocessing results part 3 suppl_material_rs_fMRI_CONN_Results_preprocessing4 rs-FC preprocessing results part 4 suppl_material_Signaling games Raw and processed data files and scripts used to analyze signaling data (upd_Signaling games.zip) regression_lHG Regression analysis with lHG as seed suppl_material_PPI_con_PPI_lHG.zip suppl_material_PPI_con_PPI_lSTG suppl_material_PPI_con_PPI_rHG suppl_material_PPI_con_PPI_rSTG suppl_material_PPI_matlabbatches VOI_coordinates
