Brain Research – MRI Therapy

Brain Research MRI Therapy

Ambience: MRI Machine
We’re listening to the sound of an MRI a magnetic resonance imaging machine. They’re being used not only to give us views of the insides of our bodies, but also as a form of therapy. I’m Jim Metzner and this is the Pulse of the Planet. Michael Friedlander is the Executive Director of the Viriginia Tech Carillion Research Institute.

Friedlander: Subjects are placed in the MRI so that we can get two types of information from them. One is structural information. The second type of information is the FMRI, or the functional imaging data. And that will be measuring the change in the delivery of oxygen to the brain tissue. This is an indirect report of the activity in the brain cells themselves.

One particularly exciting type of study is to watch the dynamics in the brain of a person who has some kind of injury to the brain, for example, that they’re trying to overcome. They may have a problem with speech, or with moving their fingers or their hand. So what one can do is , while they’re in the scanner, have them try to bring online the damaged circuitry in their brain that’s near that area to try to overcome the deficit.

So you might have somebody try to think very hard about moving a finger that right now is very difficult for them, because the primary area in the motor cortex of their brain that initiates that movement, has been damaged by a stroke. As they think very hard about it, and they activate some of the circuitry surrounding it, they may actually get a little bit of output and see that finger move. Meanwhile, they could see if they’re activating the right area of their brain. So over the course of a training session, you could see the patients learning to recover function in a damaged area of the brain.
