   Musicians have been used extensively to study neural correlates of long-term practice, but no studies have investigated the specific effects of training musical creativity. Here, we used human functional MRI to measure brain activity during improvisation in a sample of 39 professional pianists with varying backgrounds in classical and jazz piano playing. We found total hours of improvisation experience to be negatively associated with activity in frontoparietal executive cortical areas. In contrast, improvisation training was positively associated with functional connectivity of the bilateral dorsolateral prefrontal cortices, dorsal premotor cortices, and presupplementary areas. The effects were significant when controlling for hours of classical piano practice and age. These results indicate that even neural mechanisms involved in creative behaviors, which require a flexible online generation of novel and meaningful output, can be automated by training. Second, improvisational musical training can influence functional brain properties at a network level. We show that the greater functional connectivity seen in experienced improvisers may reflect a more efficient exchange of information within associative networks of importance for musical creativity.

   Functional magnetic resonance imaging (fMRI) has opened the possibility to investigatehow brain activity is modulated by behavior. Most studies so far are bound to one singletask, in which functional responses to a handful of contrasts are analyzed and reported asa group average brain map. Contrariwise, recent data-collection efforts have started to tar-get a systematic spatial representation of multiple mental functions. In this paper, weleverage the Individual Brain Charting (IBC) dataset—a high-resolution task-fMRI datasetacquired in a fixed environment—in order to study the feasibility of individual mapping.First, we verify that the IBC brain maps reproduce those obtained from previous, large-scale datasets using the same tasks. Second, we confirm that the elementary spatial com-ponents, inferred across all tasks, are consistently mapped within and, to a lesser extent,across participants. Third, we demonstrate the relevance of the topographic informationof the individual contrast maps, showing that contrasts from one task can be predicted bycontrasts from other tasks. At last, we showcase the benefit of contrast accumulation forthe fine functional characterization of brain regions within a prespecified network. To thisend, we analyze the cognitive profile of functional territories pertaining to the languagenetwork and prove that these profiles generalize across participants.

   The Individual Brain Charting (IBC) is a multi-task functional Magnetic Resonance Imaging dataset acquired at high spatialresolution, which is intended to facilitate the cognitive mapping of the human brain. It consists in the deep phenotyping of twelve individuals in a fixed environment, covering a broad range of psychological domains that allows, in turn, the investigation of atlasing techniques in functional neuroimaging. Here, we present the inclusion of task data from both naturalistic stimuli and trial-based designs, to uncover core structures of brain activation. We rely on the Fast Shared Response Model (FastSRM): an analytical tool that provides a data-driven solution to model naturalistic stimuli, typically containing many features. We show that data from left-out runs can be reconstructed using FastSRM, thus enabling the extraction of functional networks pertaining to vision, audio and language systems. We also present an in-depth study of the topographic organization of the visual system through a retinotopy task. IBC is open access: source plus derivatives imaging data and meta-data are available in public repositories.
