چکیده
|
Improvements in neuroimaging methods have afforded significant advances in our knowledge of the cognitive and neural foundations of aesthetic appreciation. we used magnetoencephalography (meg) to register brain activity while participants decided about the beauty of visual stimuli. the data were analyzed with event-related field (erf) and time-frequency (tf) procedures. erfs revealed no significant differences between brain activity related with stimuli rated as beautiful and not beautiful. tf analysis showed clear differences between both conditions 400ms after stimulus onset. oscillatory power was greater for stimuli rated as beautiful than those regarded as not beautiful in the four frequency bands (theta,alpha,beta,and gamma). these results are interpreted in the frame of synchronization studies. © 2012 munar,nadal,castellanos,flexas,maestú,mirasso and cela-conde.
