При гигиенических исследованиях актуальной задачей является поиск простых многоклеточных животных с социальным поведением для решения фундаментальных вопросов взаимодействия клеток с дестабилизирующими факторами внешней среды. К таким факторам относится световая среда, которая через спектральный состав света управляет биологическими часами живых организмов. Свет через систему ганглиозных клеток глаз и шишковидную железу с ее системой «серотонин-мелатонин» управляет «циркадными ритмами» человека. Шишковидная железа в своей структуре имеет пространственное распределение микрокристаллов СаСО3, клетки синтеза серотонина и мелатонина из триптофана, а также нейропептидную сеть. Поиск животного для исследования и моделирования процессов в шишковидной железе человека является актуальной гигиенической задачей. Таким модельным животным может стать Trichoplax (Placozoa), имеющий простейшую организацию среди известных организмов всего с шестью различными типами клеток, но с выдающимся социальным поведением. Проведен теоретический анализ спектрального состава света и степени его поляризации в морской среде обитания простейшего многоклеточного животного Trichoplax (Placozoa), а также особенностей его генно-клеточного строения. Исходя из законов гидрооптики и стратегии выживания («пища-жертва») определены координатные оси световой среды для Trichoplax: (световая вертикаль (395 нм) и две горизонтальные световые оси - отраженный горизонтальный свет от пищи (зеленый - 532 нм) и исходящий от арагонитового панциря хищника моллюска флуоресцентный свет (красный - 630 нм). На основании реакций животного на эти RGB световые стимулы высказана и подтверждена гипотеза о наличии RGB-таксиса у Trichoplax. Для управления Trichoplax выбраны монохромные световые сигналы красный - 630 нм, зеленый - 532 нм и синий - 395 нм.

When conducting hygienic research, an urgent task is to search for simple multicellular animals with social behavior to solve the fundamental issues of the interaction of cells with destabilizing environmental factors. Such factors include the light environment, which controls the biological clock of living organisms through the spectral composition of the light spectrum. Light through the system of ganglion cells of the eyes and the pineal gland with its "serotonin-melatonin" system controls the" circadian rhythms" of a person. The pineal gland in its structure has a spatial distribution of CaCO3 microcrystals, serotonin and melatonin synthesis cells from tryptophan, as well as a neuropeptide network. The search for a modal animal for the study and modeling of processes in the human pineal gland is an urgent hygienic task. Such a model animal can become a marine animal Trichoplax (Placozoa) has the simplest organization among all known animals with only six distinguishable cell types, but with outstanding social behavior. The theoretical analysis of the spectral composition of light and the degree of its polarization in the marine environment of the simplest multicellular animal Trichoplax (Placozoa), as well as the features of its gene-cell structure, is carried out. Based on the laws of hydrooptics and the survival strategy ("food-prey"), the coordinate axes of the light medium for Trichoplax are determined (the light vertical (395 nm) and two horizontal light axes - the reflected horizontal light from the food (green - 532 nm) and the fluorescent light coming from the aragonite shell of the predator mollusk (red - 630 nm). Based on the animal's reactions to these RGB light stimuli, a hypothesis is made about the presence of an RGB taxis in Trichoplax. The monochrome light signals red - 630 nm, green - 532 nm and blue - 395 nm are selected for Trichoplax control. Experimentally, within the framework of the work "Trichoplax for Bionics", the discovery of an RGB taxi in Trichoplax was confirmed. Trichoplax Movement control RGB -taxsis - YouTube
