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.
The limbic system is a set of brain structures located on top of the brainstem and buried under the cortex. Limbic system structures are involved in many of our emotions and motivations, particularly those that are related to survival. Such emotions include fear, anger, and emotions related to sexual behavior.
