Michael Levin, biologist at Tufts university discusses the role of electricity in healing and regeneration of lost organs or limbs. In a series of remarkable experiments, he showed how organisms contain information on how to heal wounds or regenerate limbs. In one experiment, by changing the voltage of certain cells, he was able to induce a tadpole to grow extra eyes. Other field changes resulted in the disappearance of cancer tumours. He suggests that all organisms already have the pattern for its healthy growth and development, stored in a morphogenetic field.
