Cryptochrome is a light-sensitive protein used for circadian rhythm regulation. Cryptochrome is also sensitive to magnetism.
Many animals rely upon magnetic field detection for spatial orientation. Magnetic sensitivity is essential for migratory animals such as birds and monarch butterflies. A gene for cryptochromes ostensibly encodes the ability.
Magnetic field sensitivity, which relies upon extra-dimensional (ed) dynamics for biological functionality, is tied to the vision system. Magnetic fields create subtly detectable visual effects that are processed by the mind-brain into useful information.
Humans have a cryptochrome gene that is highly active in the eye. But men have created continuous clouds of electromagnetic interference by their wireless communication devices, which do have a biological effect. Chronic cell phone use, for example, alters brain functioning.
