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.
One way in which the limbic system has been conceptualized is as the feeling and reacting brain that is interposed between the thinking brain and the output mechanisms of the nervous system. In this construct, the limbic system is usually under control of the thinking brain but obviously can react on its own.
