Reliability of single-subject neural activation patterns in speech production tasks.

New article just published! We looked at how reliable fMRI activation maps were from adults who participated in two simple speech studies in our lab. By focusing on a swath of cortex commonly used during speech, overlap and correlation measures were moderate to high. We then asked if they were also highly discriminable – could a computer correctly identify a participant just from their speech activation maps? Turns out you get almost perfect accuracy across 75 participants with only 1 training sample.
