Hmmmm... searching on Google was futile, too many websites on World War 2. However, from what I still remember, due to the immense stress on the soldiers, who did not want to die and thus dare not sleep, their body went extreme and adopted the sleeping style of fishes and birds. It was not permanent and lasted only as long as the stress.
Maybe it is not a case of total lobe shutdown, but a 50% reduction in brain efficiency in both lobes? *shrug*
