The distribution hypothesis of our neuron-circuit model. We hypothesize that the input cells used as the cue cells should reside in the superficial layers which receive the stimuli from the outside environment. Additionally, the motor cells used as the output cell are suitable for layer V, where the cells transmit out signals for movement. Finally, layer III is always used to integrate the information, so the four kinds of ramp cells should reside in layer III.
