Researchers used deuterium (heavy water) as a molecular probe to study water organization in rat muscle and brain tissue. They found that tissue water behaves dramatically differently from regular liquid water, with much faster relaxation times indicating highly structured, organized water arrangements. This suggests that biological water exists in organized states rather than random liquid form.

Z. V. Gordon et al. · 1969
Soviet researchers exposed albino rats to millimeter wave radiation and found it weakened their nervous system function, altered blood pressure, and caused structural changes in their brains. This 1969 study was among the first to show that millimeter waves, which are absorbed primarily by surface tissues, can still affect deep internal organs. The findings suggest these frequencies may have different biological effects compared to longer wavelengths.
Stephen Herrero · 1969
Researchers used radiofrequency current to create precise brain lesions in female rats' ventromedial hypothalamus, finding that RF and direct current lesions both led to obesity and associated disturbances, although only RF lesions caused marked increases in water intake and adrenal atrophy. Of 19 rats with RF-induced lesions destroying 50% or more of the ventromedial area, 15 developed obesity; both lesion types also reduced running-wheel activity and altered estrous cycles. The author interprets the data as showing that destruction of the ventromedial hypothalamus leads to obesity and associated disturbances regardless of whether the lesions are irritative (direct current) or non-irritative (radio-frequency current).

Researchers exposed rat stomach tissue to electrical currents at frequencies from 10 to 1,000 Hz and found that both alternating and square wave currents caused the stomach lining to depolarize (lose its electrical charge). While acid production remained normal, the electrical properties of the stomach tissue changed significantly, suggesting direct effects on cellular membranes.
