Fait-divers by Nancy Andreasen

"All human beings (and their brains) have to cope with the fact that their five senses gather more information than even the magnificent human brain is able to process. To put this another way: we need to be able to ignore a lot of what is happening around us — the smell of pizza baking, the sound of the cat meowing, or the sight of birds flying outside the window — if we are going to focus our attention and concentrate on what we are doing (in your case, for example, reading this book). Our ability to filter out unnecessary stimuli and focus our attention is mediated by brain mechanisms in regions known as the thalamus and the reticular activating system." (Nancy Andreasen)
