Patterned optogenetic stimulation and analysis of neural activity provide convergent evidence that cerebellar Purkinje cells drive eye movements with a rapid rate code, without an additional contribution of spike irregularity.
The encoding of visual images by certain retinal ganglion cells is fundamentally altered in the context of eye-movement-like image transitions; the transitions trigger inhibitory interactions, which make these cells particularly sensitive to recurring images.
New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.
An accurate, robust, and lightweight technique for measuring eye movements in mice was developed using magnetic sensing, yielding the first high resolution recordings of eye movements in freely moving mice.
Oculomotor circuits are always busy planning the next eye movement, and this explains why, when a visual target appears, some eye movements toward it are produced very quickly whereas others take a long time to prepare.
Fixational eye movements transform the spatial scene into temporal modulations on the retina, which, together with the known sensitivities of retinal neurons, provide a comprehensive account of human spatial sensitivity.
