reflex arc









































a reflex arc is a neural pathway that controls a reflex. in vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. this allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain. however, the brain will receive the sensory input while the reflex is being carried out and the analysis of the signal takes place after the reflex action.

in 1986, pellionisz described the geometrization of the "three-neuron vestibulo-ocular reflex arc" in a cat using tensor network theory. the "three-neuron vestibulo-ocular reflex arc" is named for the three neuron circuit the arc comprises. sensory input into the vestibular system (angular acceleration of the head) is first received by the primary vestibular neurons which subsequently synapse onto secondary vestibular neurons. these secondary neurons carry out much of the signal processing and produce the efferent signal heading for the oculomotor neurons. prior to the publishing of this paper, there had been no quantitative model to describe this "classic example of a basic sensorimotor transformation in the central nervous system" which is precisely what tensor network theory had been developed to model.
