Church of the Holy Laser
I enter the church and take my seat among the faithful. The priest flips a switch, and the chapel is bathed in a sea of multicolored lasers, sending the worshippers into a deep, healing, unified, spiritual state.
That is the science fiction future a neurotheologist would invent based on the intriguing research reported in the latest issue of Cell Magazine, in a paper entitled Remote Control of Fruit Fly Behavior.
Dumping the awkward electrodes and transcranial magnetic stimulation devices of the past, the researchers implanted a rat gene into a fly, programmed to function only in the neuron of the fly, and to turn itself on only in the presence of a chemical called ATP. They then engineered a “caged” version of ATP which would not affect the neuron unless released by a flash of ultraviolet light.
Zapped with a laser, the re-engineered flies, even after being cruelly decapitated, jumped up and started flapping their wings (the neuron in question was not in the brain, but a “fiber neuron” extending the length of the fly’s body).
In the church of the future, then, baptism will be your injection with the bioengineered God-genes. Sacrament will be the priest placing on your tongue the drug that activates them. Prayer will be soaking yourself in the ultraviolet light that brings them to life.
