Measuring brain pathways by tensor analysis of MRI data

MRI does it again. Using advanced mathematical analysis scientists have developed a way to take pictures of water diffusing along nerve axons. This provides a picture of how the nerves are connected or the connectome. Different pathologies will result in incorrect neural connections in the human brain. This is different from all the studies one hears about today showing which areas of the brain are active under certain conditions. This technique doesn't show directly which areas of the brain are active how they are connected.

Maintenance on a Can-Am Spyder motorcycle

Today I finally read the manual and found out how to check the fluids including oil, coolant, and brake fluid. All are easily accessible except the oil level which requires the removal of a side panel. Fortunately there are a couple of quick release things and you can bend the panel back enough to reach the filler cap without having to remove the remaining screw. The other level checks are more accessible but the levels are not easy to see. A flashlight is recommended.
