The effect of a constant and uniform magnetic field on mouse brain: a study by magnetic nuclear resonance.
Modifications in brain functions after exposure to a constant magnetic field have been noted in animals. For some authors, the main factor is the action of magnetic fields on tissular water. The relaxation times obtained by proton nuclear magnetic resonance should therefore be modified. Mice were placed in a 0.6 T constant magnetic field for 2 h. Their brain relaxation times (spin-lattice T1 and spin-spin T2), were measured 1-5 d after exposure and do not seem compatible with an initial and important modification of the water structure.
