ABSTRACT
Laser-like long-range coherent quantum phenomena resulting from the instantiation of superradiance and self-induced transparency take place in microtubules of the cytoskeletal network. By taking into account the often neglected interaction between the electric dipole of water molecules confined within a microtubule and the quantized electromagnetic field, it is shown that microtubules play the role of non-linear coherent optical devices. Unlike laser phenomena, superradiance is a specific quantum mechanical ordering phenomenon with characteristic time much shorter than that of thermal interaction, so microtubules may be thought to form an ideal optical network free from both thermal noise and loss. Such a superradiant optical network in cytoskeletal microtubule structure may provide us with a new understanding of holographic brain activity, biophoton emission and the origin of anesthesia.
