Magnetocyte
comment 2 Information about magnetocyte is very rare. There is more information about brain magnetite. If magnetite exist it naturally is in cells. And there is information that specific cell type containing magnetite/magnetosomes exist. Sorry I cant find more material. New cell type information is exremely important to publish, it may generate some magnetobilogical expert to add more data later.
Magnetocyte Is living organ cell that contain magnetite crystall structures [1] called magnetosomes. [2] [3] Magnetite crystals are found in many animals brains including human. [4] [5] [6] [7] [8] [9] [10] [11] [12] [13]
In human brains there are at least two types of magnetocytes. One differentiating from brain cells and another from immune system cells. [14]
Magnetocyte density in brain tissues amounts to 1–2 cells per 1 g of tissue, though concentrations are higher in the thalamic nuclei and hippocampus. [15] Magnetite concentration varies between 3-10 ng/g tissue (human brain) and in mouse brain range from 0.6 to 17.1 ng/g tissue, average 4.8 ± 4.0 ng/g tissue. [16] [17] [18]
There are findings in many mammalian brain tissues magnetite crystals containing cells called magnetocyte. Magnetocytes exist only less than 1/5000 number of brain cells. Magnetite crystals are in magnetosomes that are inside magnetocyte. Mammalian magnetosomes are different from bacterial one. There are smaller super paramagnetic magnetite crystalls in magnetocyte. In mammalian magnetocytes there is from 1000 to 10000 small 10nm magnetite crystals and magnetite is not arranged linear chains like in magnetotactic bacteria. It can be say that magnetite crystals in such cells are arranged position that geomagnetic field don't disturbate them. Magnetocytes function is yet unknown and function are definitely not to detect geomagnetic field. [19] Magnetoacoustic sense need to investigate. It is posible that Shuman 7.8Hz resonance carry information between magnetocytes. [20] [21]
