In this study, the cortical activity correlated with the perception and appreciation of different set of pictures was estimated by using neuroelectric brain activity and graph theory methodologies in a group of artistic educated persons. The pictures shown to the subjects consisted of original pictures of Titian's and a contemporary artist's paintings (Orig dataset) plus two sets of additional pictures. These additional datasets were obtained from the previous paintings by removing all but the colors or the shapes employed (Color and Style dataset, respectively). Results suggest that the verbal appreciation of Orig dataset when compared to Color and Style ones was mainly correlated to the neuroelectric indexes estimated during the first 10 s of observation of the pictures. Always in the first 10 s of observation: (1) Orig dataset induced more emotion and is perceived with more appreciation than the other two Color and Style datasets; (2) Style dataset is perceived with more attentional effort than the other investigated datasets. During the whole period of observation of 30 s: (1) emotion induced by Color and Style datasets increased across the time while that induced of the Orig dataset remain stable; (2) Color and Style dataset were perceived with more attentional effort than the Orig dataset. During the entire experience, there is evidence of a cortical flow of activity from the parietal and central areas toward the prefrontal and frontal areas during the observation of the images of all the datasets. This is coherent from the notion that active perception of the images with sustained cognitive attention in parietal and central areas caused the generation of the judgment about their aesthetic appreciation in frontal areas.
在本研究中，通过运用神经电活动和图论方法，对一组接受过艺术教育的人群进行了评估，以确定与不同图片集的感知和欣赏相关的皮层活动。向受试者展示的图片包括提香的原画以及一位当代艺术家的画作（原始数据集），外加两组额外的图片。这些额外的数据集分别是通过去除原始画作中除颜色或形状之外的所有元素而获得的（颜色数据集和风格数据集）。结果表明，与颜色数据集和风格数据集相比，对原始数据集的言语欣赏主要与图片观察最初10秒内估计的神经电指标相关。同样是在观察的最初10秒内：（1）原始数据集比其他两个颜色和风格数据集引发了更多情感，且被感知为更具欣赏价值；（2）风格数据集比其他研究的数据集需要更多的注意力投入。在30秒的整个观察期内：（1）颜色和风格数据集引发的情感随时间增加，而原始数据集引发的情感保持稳定；（2）颜色和风格数据集比原始数据集需要更多的注意力投入。在整个体验过程中，有证据表明，在观察所有数据集的图像时，皮层活动从顶叶和中央区域流向额叶和前额叶区域。这与以下观点一致，即在顶叶和中央区域持续认知注意力下对图像的主动感知会导致在额叶区域产生对其审美欣赏的判断。
