    The memory might be maintained in the nervous system.
    Other than that, perhaps genes which control production of chemicals in response to light
    have been turned on or off.

    Amazing little creatures.
    They have so much, packed into such a compact body.
    In a few million years, they could be anything.

    The easiest way to explain this is with the nerve ladder. This is smart tissue with a relationship to memory. After a worm grows, there is a memory image of an entire worm stored in the nerve ladder. If we cut off the head, the image of the entire worm is retained like a back-up file. System-restore is then activated and the body is returned back toward the image in the back-up file. The back-up data image is not in the head but within the nerve ladders.

    This could be done using simple energy potential. Sensory nerves fire neurons and cause cationic current to flow. If we cut off the head, we loose a large block of sensory nerves, such that the potential coming down the nerve ladder is less. Since the head now regrows, this would imply the firing had a negative feedback effect, that inhibits cell growth. As we fire less, due to loss of head, growth is less inhibited and cells divide back to the data image.

    In our own bodies, nerves are part of the control system that inhibits run away cell growth. In the skin, where there are many nerves, if we cut ourselves, we also cut nerves and lose negative feedback, allowing these specific cells to grow. Cancer could be due to loss of negative feedback from the local nerve system; Cancer does not have nerves and lacks a back up data image.

    From what I remember there is a part on the head if you cut it does not regrow ?
