Definition of Midline. The midline is a horizontal axis that is used as the reference line about which the graph of a periodic function oscillates. The equation of the midline of periodic function is the average of the maximum and minimum values of the function. Figure-1 shows y = sin x and Figure-2 shows y = sin x + 1. The second curve is the first curve shifted vertically up by one unit.
The brain is divided into two hemispheres. When seen on a CT scan, the hemispheres are quite symmetrical. When seen from above, a reasonably straight line can be seen between the two sides of the brain. If the brain is swelling on one side, it pushes one hemisphere across this center line. This is called a âmidline shift.â A midline shift is one of the most obvious evidences of brain swelling that can be seen on a CT scan. A midline shift can be particularly dangerous as it may be accompanied by compression of the brain stem, which can be fatal. For an example of a midline shift, click here.
