Abstract
Several studies have been published which show that it is possible to
decode semantic representations directly from brain responses. This has
been repeatedly successful when the stimuli used were pictures of
objects. However, there is a distinct scarcity of studies decoding
responses to orthographic stimuli, particularly those employing
time-sensitive imaging methods. We use examples from our own research to
highlight the challenges we have faced when attempting to decode
semantic representations from MEG responses to written words. We discuss
differences in brain responses to pictures and orthographic stimuli to
determine the characteristics of the brain responses that allow for
successful decoding of semantics. We suspect the limited number of
published studies on this topic indicates that these challenges are not
unique to our experience. By bringing attention to these issues, we hope
to stimulate a new wave of discussion leading to eventual progress.
