microsaccades

Before the subjects reported periods of faster motion, their rate of microsaccades — tiny eye movements that occur any time when we ' re looking at an object — increased.

I asked if you could look into someone eyes and tell where they're paying attention, and he said there are these microsaccades, these really tiny eye movements that are sort of correlated to attention.

Each channel was sampled at 250 Hz. The system has a spatial resolution of 0. 025° in pupil-CR mode and saccade event resolution of 0. 05° for microsaccades (see manufacturer specification).

This idea remains to be proven, Hafed concedes, but such a loop could explain why we seldom notice microsaccades: the brain expects the slight movement and somehow subtracts it as it processes incoming signals from the retina.

Blue shows a gentle movement called "drift," while red shows quick, jerky movements called microsaccades.

One potential job for microsaccades is to compensate for a need for change among light-sensitive cells in the eye, Hafed says.

To confirm the finding, Hafed and his colleagues temporarily deactivated some of the control neurons, and found a reduction in the number of microsaccades. saital

In a study of primates, Hafed monitored the activity of individual neurons in the superior colliculus, and found that not only do these cells command microsaccades, but that each cell actually defines a specific type of movement.

This finding could shape the argument over the role of microsaccades, Hafed adds, because neurons in the superior colliculus also connect to other parts of the brain's visual apparatus.

Over the years, microsaccades became the subject of a "raging debate," Hafed adds.

When participants solved problems analytically, their eyes instead made tiny, rapid movements known as microsaccades.
