Parafovea - Wikipedia
Parafovea or the parafoveal belt is a region in the retina that circumscribes the fovea and is part of the macula lutea. [1] It is circumscribed by the perifovea. Photograph of the retina of the human eye, with overlay diagrams showing the positions and sizes of the macula, fovea, and optic disc

Differences between fovea and parafovea in visual search processes
Tachistoscopic presentations of textures were used to compare the time course of search processes in the fovea and parafovea. Detection of targets differing for a simple feature (line orientation or line crossings) from the surrounding elements was found to have a time course typical of parallel processing for coarse textures extending into the ...

视网膜上中央凹（fovea）和视网膜周边（retinal periphery）的结构存在一些差别。 有超过500万的视锥细胞在中央凹上，然后以其中心向周边迅速减少。 视杆细胞不存在于中央凹上，它们主要存在于视网膜的周边。

2015年1月1日 · The parafovea may refer to a position at a visual angle of approximately 4° from the normal fixation point or to the region extending to that angle from the fovea. It is compositionally distinguished from the fovea by its lower cone and ganglion cell densities and by its higher rod density.

The area outside the fovea is further divided into two functionally distinct regions: parafovea and periphery. The parafoveal area extends up to 5° of visual angle to the right and left from the fixation point, while the visual periphery refers to the area beyond the parafovea.

Definition. The parafovea may refer to a position at a visual angle of approximately 4 from the normal fixation point or to the region extending to that angle from the fovea. It is compositionally distinguished from the fovea by its lower cone and ganglion cell …
Here, we report results on the use of word information from the parafovea for eye-movement control during reading. We present an explicit computational model of parafoveal processing in an ...
In sum, the present study demonstrates that RIFT is a powerful tool for investigating natural reading, and provides neural evi-dence for lexical parafoveal processing in support of parallel graded...

2024年8月18日 · The region surrounding the fovea is called the parafovea; it stretches about 1,250 microns from the centre of the fovea, and it is here that the highest density of rods occurs.
