The proliferation of gray matter and white matter studies in social neuroscience. Both types of research have been rapidly increased over the past 15 year; however, the number of white matter studies per year is always less than 1/3 of the number of gray matter studies. The plotted data were extracted from https://www.ncbi.nlm.nih.gov/pubmed/ on 4/30/2017, using the search term “(social) AND (gray matter OR fMRI OR functional imaging)” for gray matter research (gray bars) and “(social) AND (white matter OR DTI OR diffusion imaging)” for white matter research (white bars).
