Photoreceptor and ganglion cell topographies correlate with information convergence and high acuity regions in the adult pigeon (Columba livia) retina

Querubin, Angeliza; Lee, HieRin; Provis, Jan; Bumsted O'Brien, Keely


The fovea and area dorsalis are high acuity vision regions in the pigeon retina. However, the degree of neural convergence (an important determinant of acuity) has not been quantified consistently in this bird. The purpose of the study was to determine the topographic density changes and degree of photoreceptor to ganglion cell convergence in the fovea and the area dorsalis. Total photoreceptor and ganglion cell densities were calculated on the horizontal and vertical meridia. In four eyes,...[Show more]
