As a last resort for epilepsy, this bundle can be cut in a procedure known as a callostomy. When this happens, a split-brain patient … Continue reading Split-Brain Patients

In imaging, there are certain methodologies, like the cognitive subtraction methodology. In this method, activity in a control task in subtracted from activity in an experimental task. So for example, take a word task. A simple model of written word recognition is used. In a famous experiment, the Peterson et al. (1988) experiment, they wanted … Continue reading Cognitive Substraction: Why Brain Imaging Techniques aren’t always accurate
Brain Imaging Alphabetical Soup: Making Sense of CAT, PET, MRI, fMRI, SPECT: MRI
I started this mini-series with the articles on how imaging got started, and on CT scans. Now we'll move on to MRI scans.MRI, or magnetic resonance imaging, is used to create images of the body's tissues, specifically of the soft tissues, like organs. X-rays pass through soft tissues undistorted and relatively easily. Now, most human … Continue reading Brain Imaging Alphabetical Soup: Making Sense of CAT, PET, MRI, fMRI, SPECT: MRI

The similarity of this disorder to BIID, coupled with the childhood onset of these disorders, suggest both may be congenital disorders, that is, present from birth. The disorder is a … Continue reading Somatophrenia
