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 major portion of the brain, the cerebrum, develops during this second stage of CNS development. The cerebrum has two parts: the outer layer (cerebral cortex) and the inner layer (cerebral medulla). The cerebrum is the structure most of us picture when we think about what a brain looks like.
