Figure 5.

An example response of a vestibular nucleus (VN) neuron to roll body rotation, hindlimb movement, and both movements delivered simultaneously. The response to simultaneous delivery of roll and limb stimuli results from the weighted sum of the individual components. A: the observed firing rate (blue dots) and the modeled firing rate (orange solid line, see Iterative Modeling Strategy for Vestibular and Limb Signal Identification) are shown. B: the individual signal components for the unit in A are plotted (with the exception of baseline firing rate, which is a flat line). C: limb and table position. HP, high pass; LP, low pass.
