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

Don’t learn to code

With the push to learn code, which I am now a part of, I think we have lost sight of what it means to be a computer programmer.My SO sent me this link, which I think makes sense: Don't learn to code. Learn to think.I think it is well worth a read:http://brikis98.blogspot.gr/2014/05/dont-learn-to-code-learn-to-think.html

Somatophrenia

Look at the right side of your body. It’s yours, right? Or maybe it’s your neighbor’s… Somatoparaphrenia is caused by damage to the right parietal lobe. 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

Brain Imaging Alphabetical Soup: Making Sense of CAT, PET, MRI, fMRI, SPECT: CAT Scans

We've all heard the abbreviations: CAT, PET, MRI, fMRI, SPECT.Now what the heck do they all mean? Brain imaging has an interesting start. But generally, brain imaging techniques fall into two broad categories: Structural imaging, and Functional imaging. Structural imaging does just what its name implies: it provides images of the structure of the brain. … Continue reading Brain Imaging Alphabetical Soup: Making Sense of CAT, PET, MRI, fMRI, SPECT: CAT Scans

Mosso and Bertino: Brain Injury to Imaging Inventions

The earliest ways of peering into the brains of people was invasive, and sometimes, fatal. Consequently, most subjects were those who were mentally disabled, those who had mental illnesses. Therefore, we now know more about dysfunction than we do function. However, this isn’t a bad thing, considering that it’s through dysfunction that we can better … Continue reading Mosso and Bertino: Brain Injury to Imaging Inventions

A neuron can be represented as an electrical equivalent circuit

A neuron can be represented as an electrical equivalent circuit, which is a mathematical model that represents all of the major electrical properties of a given neuron. An equivalent circuit is made up of batteries, capacitors and resistors.Basically, the model gives us a relatively intuitive idea of how currents are caused by ionic movement and … Continue reading A neuron can be represented as an electrical equivalent circuit
