Living organisms can produce magnetite. C'est sur ce type d'étude qu'est basé mon roman "Les Voix des Autres". Magnetite is one of the most magnetic substances on Earth. Many animals also have magnetic particles in their brains. Magnetite was identified in ancient times, but it took until the 1990s—when high-resolution electron microscopes were finally available to scientists—to discover them in the brain. Medical Hypotheses 74 (2010) 254–257. Much smaller ones of course. They found magnetite concentrated in the same places in all seven brains—primarily in the cerebellum and brain stem, as shown in the figure. A striking asymmetry also exists in the distribution of particles between the right and left hemispheres. M A Martínez Banaclocha, I Bókkon, H Martínez Banaclocha. Abstract: Biomagnetite, as clusters of magnetic nanocrystals, has been documented in human brains. It's possible, however, that other kinds of magnetic particles exist in the brain besides magnetite, Gilder noted. Magnetite is not usually found in the human brain… That might sound strange, but there has long been evidence that some amount of magnetite might form naturally in brain tissue. A type of iron called magnetite may lead researchers down the path to a more effective treatment for Alzheimer’s disease. This is Your Brain on Magnetite by Iona Miller, 2014. In humans, magnetite can be found in various parts of the brain including the frontal, parietal, occipital, and temporal lobes, brainstem, cerebellum and basal ganglia. Still, not all magnetite is created the same, it would seem, and a study published last week in the Proceedings of the National Academy of Sciences suggests another possible origin: air pollution. As you can probably guess, it has a diverse range of uses; from fridge magnets to generating electricity in power plants. Human brain. Particles of magnetite might be polluting our brains. It plays a significant role in the nervous system. Barbara … Long-term memory in brain magnetite. BIBLIOGRAPHIE (pour ceux d'entre vous qui sont intéressés) But what you probably wouldn’t guess is that your brain actually synthesizes these crystals, and you have hundreds of millions of them inside your head.
