Did You Know? #3: Magnetite Crystals
January 22, 2009 -- Written by: Tim Johnson
Migratory birds, mammals, Salmon and other animals are known to have “Magnetite Crystals” incorporated into geometric patterns in their brains that may effectively give them another sense – the sense of direction. Humans also carry Magnetite Crystals, however they are scattered about the brain in no particular pattern. This may mean that through the use of visual landmarks and other tools humans have evolved out of having this sense of direction.
