Several papers have investigated the effect of stroke on creativity. While initial evidence favored right hemispheric dominance in artwork creation, subsequent well-founded research has established the left hemispheric participation in creativity, supporting the idea of bi-hemispheric role in artistic production. We here describe the case of a renowned artist who suffered a left hemispheric ischemic stroke involving the occipito-temporal region and subsequently manifested several difficulties in producing visual artworks. We documented his recovery phases in a prospective way during the initial months following stroke and observed that, although his constructional abilities recovered to a significant extent over 3 months, spontaneous creation was persistently impaired. The right hemispheric role in visual art is linked mainly to visuo-spatial skills and global attention, while left hemispheric participation is thought to be related to focal attention and visual imagery. Our case study lends support to the idea that art is a bi-hemispheric function with important complementary contributions from both the right and left hemisphere.
已有多篇文献探讨了卒中对创造力的影响。虽然最初的证据支持右半球在艺术创作中占主导地位,但随后有充分依据的研究确立了左半球在创造力中的参与,支持了艺术创作中双侧半球共同作用的观点。在这里,我们描述了一位著名艺术家的病例,他患有左半球缺血性卒中,累及枕颞区,随后在创作视觉艺术作品时出现了多种困难。我们采用前瞻性方法记录了他在卒中后最初几个月的恢复阶段,并观察到,尽管他的结构能力在 3 个月内得到了显著恢复,但自发创作能力仍持续受损。右半球在视觉艺术中的作用主要与视觉空间技能和全局注意力有关,而左半球的参与被认为与焦点注意力和视觉意象有关。我们的病例研究支持这样一种观点,即艺术是一种双侧半球的功能,右半球和左半球都有重要的互补作用。
