Gaming in an MRI Machine - Toyota's Surprise Findings
Lying on his back, a man is engrossed in a game as he is pulled into the tunnel of an MRI machine.
These machines are elaborate instruments capable of examining cross-sections of the body to check for disease. Heading into a scan with a controller in hand may hint at a gaming obsession, yet this is anything but child’s play. It is all part of Toyota’s groundbreaking research.
Having people play games with a steering wheel-style controller inside an MRI machine is actually part of research that aims to determine which parts of the brain, including the spinal cord, are activated by moving the arm muscles.
Recent advances in MRI technology have astonishingly made it possible to clearly identify neural connections at the level of nerve fibers. The image above shows the result when cranial nerves are captured in detail using a technique called Diffusion Tensor Imaging (DTI).
Furthermore, the researchers have found that the brain behaves differently during unconscious and voluntary hand movements.
According to the research team at the RIKEN CBS-TOYOTA Collaboration Center (BTCC), until the last 20 to 30 years, measuring brain temperature meant sticking a probe directly into the tissue.
In recent years, this crude approach has been replaced by MRI, as increased sensitivity enables cross-sectional images to map temperature changes in the brain.
Just as physical exercise warms up the body, the brain’s temperature rises after a hard day of using your head at work. That comic strip staple of steam coming out of a character’s head is not far off the mark.
