Slow eye movement
Webb13 apr. 2024 · We measured the impulse responses of the compound eye and found their response duration (42 ms) was similar to that seen in other slow-moving ants. We determined the flicker fusion frequency of the compound eye at the brightest light intensity to be 132 Hz, which is relatively fast for a walking insect suggesting the visual … Webb1 aug. 2024 · Pendular nystagmus refers to the waveform of an involuntary eye movement. In pendular nystagmus the eye moves in sinusoidal trajectory, similar to that of a pendulum. Pendular nystagmus generally does not have a "fast phase" including a saccade, but is composed entirely of slow eye movements.
