Abstract

When the head is rotated about an axis tilted from the vertical, in total darkness, compensatory eye movements, with a velocity approximately equal to that of the head, are generated and persist indefinitely. This study implements a neural network model which could be trained to produce this velocity estimation and to explicitly but naturally include the tilt angle normalization. A feedforward network was used, with connection weights determined by back-propagation. The input to the network is a pattern of otolith cell excitations as in the mathematical model. Its output is a single activation representing a velocity estimate.
