This question continues to elude the neuroimaging field due to at least two kinds of problems: first, the relatively low spatial resolution of fMRI and second, the bias inherent in prevailing statistical methods for analyzing the actual diagnosticity of cortical tissue. We collected high-resolution (1mm x 1mm) imaging data of the fusiform face area (FFA) from 4 subjects while they categorized images as 'animal', 'car', 'face', or 'sculpture.' We performed exploratory analysis to determine the nature of the distributions over classes and the similarity structure between classes. The FFA was visualized using nonmetric... |
