“Spinal Conduction and Kinesthetic Sensitivity in the Maze Habit”, 1929 (; backlinks):
Rats having serious sensory disturbances, induced by sectioning of the upper cervical region of the cord with consequent interruption of the dorsal, lateral, and ventral funiculi, can still run the maze.
Control experiments, while not suggesting the falling back upon exteroceptive cues, suggest that the behavior is not referable to the remaining proprioceptive sensitivity, but rather to intra-neural mechanisms capable of producing an integrated sequence of movements in the absence of directive sensory cues.
