Neurophysiologic information such as quantitative electroencephalography is used in a method for classifying, diagnosing, and treating physiologic brain imbalances. The image display apparatus receives an image signal corresponding to an image to be displayed, stores the received image signal in a buffer on a partial-image-by-partial-image basis, and corrects the image signal so that correction appropriate to an optical system of a display associated with each of the plurality of partial images is applied to the partial image. A second external storage device includes software and is also electrically coupled to the diagnostic tool. Nucleic acids encoding these antibodies, vectors including these nucleic acids, and host cells transformed with these vectors are also disclosed herein. Furthermore, this system minimizes the amount of time a network administrator spends on attending to users who have no remaining hard drive space on their computers. The x-ray detector includes a detector subsystem configured to output electrical signals in response to reception of x-rays.
