Simplifying, it's thought by some it may be related to the difference between the anatomical flexors behaving differently, more as extensors.

Paralyzis in one limb initiated 2 weeks post scoliosis surgery. clonus spasms and dorsal back pain. upper motor neuron lesion? why? Mri and CT normal.
Lesion Localization: The upper motor neurons also called “Cortical Motor Neurons” are located in the motor cortex of the brain. The the spinal motor neurons are the lower motor neurons. Signs of UMN is a stiffness and resistance to movement. Signs of LMN damage include weakness, muscle atrophy. Hope it helps. ...Read more
Maybe, if...: ... you're a lab rat being given huge doses. No evidence caffeine is "neurotoxic" in us. "Neurotoxicity" used as you are using it is like saying your car has "engine trouble": It's meaningless without a specific definition. Which nerves? We have a lot of different kinds. Timeline?
