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 structures of the limbic system are involved in motivation, emotion, learning, and memory. The limbic system is where the subcortical structures meet the cerebral cortex. The limbic system operates by influencing the endocrine system and the autonomic nervous system.
