How does the brain mediate visual artistic creativity? Here we studied behavioral and neural changes in drawing and painting students compared to students who did not study art. We investigated three aspects of cognition vital to many visual artists: creative cognition, perception, and perception-to-action. We found that the art students became more creative via the reorganization of prefrontal white matter but did not find any significant changes in perceptual ability or related neural activity in the art students relative to the control group. Moreover, the art students improved in their ability to sketch human figures from observation, and multivariate patterns of cortical and cerebellar activity evoked by this drawing task became increasingly separable between art and non-art students. Our findings suggest that the emergence of visual artistic skills is supported by plasticity in neural pathways that enable creative cognition and mediate perceptuomotor integration.
大脑如何介导视觉艺术创造力?在这里,我们研究了与未学习艺术的学生相比,绘画学生的行为和神经变化。我们调查了对许多视觉艺术家至关重要的三个认知方面:创造性认知、感知和感知到行动。我们发现,艺术学生通过前额叶白质的重组变得更具创造力,但相对于对照组,艺术学生在感知能力或相关神经活动方面没有发现任何显著变化。此外,艺术学生提高了从观察中描绘人物的能力,并且由这项绘画任务引起的皮质和小脑活动的多元模式在艺术学生和非艺术学生之间变得越来越可分离。我们的发现表明,视觉艺术技能的出现得到了支持创造性认知和介导感知运动整合的神经通路可塑性的支持。
