title: Adjusting the light in the limit conditions of consciousness by the means of ascending reticular activating system (ARAS) and of subordinated systemsPart 2: Continuation ^|^amp; Conclusion of the Article
abstract: We found a perfect interpenetration between the ARAS and the following two complementary subsystems: 1. The hypothalamic suprachiasmatic nucleus, that has the role of coordinating the periodicity of some biological functions depending on the circadian rhythm; and 2. The main photoperiodic organ, the pineal gland (epiphysis), which together with the ARAS has a role in the photoperiodicity modulation of some biological functions during the state of vigilance.
