Neuroscience: The mind reader 2012-06-13T17:20:30.750Z One thing is clear though, this underlying principle is used in vast majority of neuroimaging methods, including fMRI, and the reported results one way or another catch everyone’s attention. Controversial science of brain imaging 2012-07-05T15:45:03.313Z Fearful brain changes Minutes after therapy, participants were again shown spider photos, but this time, their fMRI scans showed less activity in the fear regions. 2-Hour Therapy Cures Spider Phobia by Rewiring the Brain 2012-05-22T16:15:06.893Z Some people like to use the salmon study as proof that fMRI is woo, but this isn’t the case, it’s actually a study to show the importance of correcting your stats. IgNobel Prize in Neuroscience: The dead salmon study 2012-09-25T15:15:06.347Z Those orange blobs in the image above are actually clusters of voxels—perhaps tens or hundreds of them. fMRI is also too slow to capture all of the changes in the brain. What's a voxel and what can it tell us? A primer on fMRI 2012-06-21T21:45:00.567Z The ambiguity forces the brain to work harder and shows up in characteristic fMRI patterns in healthy people — if, that is, they are comprehending the words. Neuroscience: The mind reader 2012-06-13T17:20:30.750Z Furthermore, another dilemma that always haunts correlational research such as fMRI is that because two things occur at the same time does not prove that one thing causes the other.

Unhurtful Thoughts: A Preoccupied Brain Produces Pain-Killing Compounds 2012-05-17T19:15:00.223Z Having procured the specimen, the authors placed the salmon in the fMRI and ran all the usual anatomical scans, and then ran the experimental set of the study as well. IgNobel Prize in Neuroscience: The dead salmon study 2012-09-25T15:15:06.347Z Trying to explain whether activity in one spot causes activity in another is not possible through fMRI alone. What's a voxel and what can it tell us? A primer on fMRI 2012-06-21T21:45:00.567Z Given those earlier findings, the fMRI data reported by Dr. Nutt’s group are somewhat surprising.
