 More recent philosophical discussion of these functional imaging techniques has tended to urge more caution resting localization claims on their results. Roskies (2007), for example, points out the tendency to think of the evidential force of functional neuroimages (especially fMRI) on an analogy of that of photographs. Drawing on work in aesthetics and the visual arts, Roskies argues that many of the features that give photographs their evidential force are not present in functional neuroimages. So while neuroimages do serve as evidence for claims about neurofunctions, and even for localization hypotheses, details of their proper interpretation are far more complicated than philosophers sometimes assume. More critically, Klein (2010) argues that images of “brain activity” resulting from functional neuroimaging, especially fMRI are poor evidence for functional hypotheses. For these images present the results of null hypothesis significance testing on fMRI data, and such testing alone cannot provide evidence about the functional structure of a causally dense system, which the human brain is. Instead, functional neuroimages are properly interpreted as indicating regions where further data and analysis are warranted. But these data will typically require more than simple significance testing, so skepticism about the evidential force of neuroimages does not warrant skepticism more generally about fMRI.
