Neuro-muscular model of ocular microtremor

This paper investigates two implementations of the neuro-muscular model of the fine tremor of the eye known as ocular microtremor (OMT). The neurological model assumes that the spectrum of tremor reflects the distribution of firing frequencies among oculomotor neurones. The neuro-mechanical model assumes that the OMT spectral peak reflects the mechanical resonance of the eye. The results indicate that: (i) the neurological model is not consistent with published data; (ii) the neuro-mechanical model is plausible, provided the resonant frequency of the eye is assumed to be about 75Hz, and the damping factor is assumed to be about 0.2.
