The size and location of single and multiunit receptive fields were plotted in azimuth and elevation relative to the area centralis. As no significant spatial gradients were detected for these cells at these ages, no attempt was made to define an area centralis or visual streak. The ventral-temporal retinal location of the zebrafish area centralis serves to enhance vision in the upper-frontal visual space. This area is also referred to as the fovea centralis. We plotted and projected retinal landmarks, including the optic disk and area centralis, onto the tangent screen. In the cat, it coincides with the area centralis. The highest densities of neurones in the ganglion cell layer were in temporal retina but no well-defined area centralis was observed. The highest densities of cells were located in region of ventro-temporal retina, subtending a frontal visual axis, but there was no well-defined area centralis. Each pixel corresponded to approximately 1 of a degree in the 4 area centralis. Note that at least three cells were exceptions to this trend with preferred directions towards the area centralis. The cross marks the approximate position of the area centralis. Retinal landmarks (optic disk and area centralis) were projected onto a plotting screen with a reversible ophthalmoscope. For example, the ocular dominance columns representing regions around the area centralis in area 17 are less densely labeled compared to more peripheral retinal representations. The electrode was viewed by direct ophthalmoscopy and, in this set of experiments, positioned to record from the area centralis. These examples are from corpora and from sources on the web.
