We considered at this stage, the processes were unconscious. Investigations of the hypothalmus, limbic system and circumventricular organs followed.
Only molecules less than 500 Daltons can pass into the conscious brain. The actions of signalling hormones and their neural pathways do not appear to cross the blood-brain (CSF)-barrier.
From this information, it is logical to assume we have two brains: the consious one (cerabal cortex, cerebellum, brainstem and spinal cord) for thought, learning, emotion and memory, and the unconscious brain (outside the blood-brain/CSF-barrier), which conducts physiological tasks necessary for balance (homeostasis), protection and survival (immune response). We also noted, as the small compond in both UV/IR modes were less than 500 Daltons, and could easily pass through the blood-brain/CSF-barrier.
The conscious brain cells also needs to maintain metabolism, growth, homeostasis, have an immune response system and deal with apoptosis.
As the small compound has two structures, a weak bonded stucture during UV radiation which synthesises one hormone, and a strong bonded during IR stimulus, which synthesises the other hormone. Perhaps it does not release the hormones in the mitochondrial sac but carries them as a neurotranmitter to the hypothalamus and then releases either neurotransmitter hormones?
This evidence so far suggests, what our body needs in terms of essential nutrients (food) water (drink) and comfort are unconscious actions to maintain homeostasis triggered by weather stimuli. Maslow's theory "Hierarchy of Human Needs" appears to be valid.
