WebThese issues are described further elsewhere in fMRI for Newbies in the fMRI Design slideshow. I think that in trying to avoid spurious results (Type I errors), many of us err on the side of overcorrecting and disregarding activation that is real (Type II errors). Some scientists regularly use thresholds like p < 10-20. WebDec 4, 2024 · Magnetic Resonance Imaging (MRI) has given doctors the ability to obtain very good images of the brain's structures. A newer technique known as functional MRI can go even farther by indirectly measuring brain activity as well. While most of the time the technique is used only in research studies, it is becoming more common in the clinical …
