The mechanism of the semicircular canal. A study of the responses of single-fibre preparations to angular accelerations and to rotation at constant speed

Single-fibre discharges have been recorded from the horizontal ampulla of the isolated labyrinth of Raja. A basis is provided for the interpretation of labyrinthine tone, and of the reflex responses to rotation of unilaterally operated animals. The sensory activity of the semicircular canal provides a framework accounting for nystagmus and after-nystagmus.
