But another theory says that sleep allows the activation of neuronal
circuits not used (and rather suppressed) during waking, thus preventing
them from being degenerated, and preserving their capability to react to
possibly changed life conditions (Krueger & Obal,
Journal of Sleep Research 2:63-69, 1993).
