![]() ![]() This neural system included regions in posterior temporal cortex associated with identifying human faces and other biological objects. Vignettes interpreted as conveying social interactions elicited a distinct and distributed pattern of neural activity, relative to vignettes interpreted as mechanical actions. ![]() To investigate this issue, functional magnetic resonance imaging (fMRI) was used to record changes in neural activity while subjects interpreted animated vignettes composed of simple geometric shapes in motion. ![]() ![]() However, the extent to which these category-related activation patterns reflect differences in conceptual representation remains controversial. Motivated by neuropsychological investigations of category-specific impairments, many functional brain imaging studies have found distinct patterns of neural activity associated with different object categories. ![]()
