In Win7, if you right-click on the background and pick Screen Resolution, you should get a dialog which has Orientation among the options, letting you pick Landscape or Portrait. This should make it easy to configure the way you want.
Introduction. The forebrain (proencephalon) is the largest part of the brain, most of which is cerebrum. Other important structures found in the forebrain include the thalamus, the hypothalamus and the limbic system.
For these children, the limbic system is often on overdrive. The limbic system is embryologically older than other parts of the brain. In fact, it is called the old brain because it existed tens of millions of years ago, long before the brain developed higher reasoning function and symbolic language.
