Most current transcultural neuroimaging studies have compared people from Western and East Asian cultures. People from North American and European countries are considered to be Western, whereas people from China, Japan or Korea are considered to be East Asian. This raises problems regarding the homogeneity of cultural groups, because there might be country-specific aspects to cultures even within a broad cultural group. The problems become even more significant when considering factors like education and aging that might also interact with the neural substrates of culture-dependent cognitive differences.
