Maturana Romesín, Humberto; Varela G., Francisco (1982)Extracellular recordings were made from cells in the ventral lateral geniculate (GLv) of the Japanese quail (Coturnix coturnix japonica), and their responses studied with chomatic stimuli. A total of 156 units were studied, ...

Guiloff, Gloria D.; Maturana Romesín, Humberto; Varela G., Francisco (1987)The avian thalamic ventral lateral geniculate nucleus (GLv) was studied by light microscopic techniques in order to understand its anatomy, neuronal composition, and the nature of its retinal and tectal afferents. The avian ...

Maldonado Arbogast, Pedro; Maturana Romesín, Humberto; Varela García, Francisco (Karger, 1988)Birds exhibit a variable retinal organization in terms of foveas and areas of high cell density. The distribution of these retinal structures in different species does not follow phylogenetic lines. In order to study this ...

Budnik, Vivian; Mpodozis Marín, Jorge; Varela G., Francisco; Maturana Romesín, Humberto (1984)The ganglion cell density of the quail's retina was studied in sections and whole mounts. Two regions of high ganglion cell density were found, corresponding to an afoveate area centralis and an area dorsalis. Oil droplets ...

Varela, Francisco G. (1971)This paper discusses, first, the selective pressures which led to the two basic types of animal eyes, compound vs. camera eyes. Secondly, it considers what is the significance of the apparent similarity of the wiring ...

Letelier, Juan Carlos; Varela G., Francisco (1984)We examine the arguments advanced recently [by Sakitt (Vision Res. 22, 417-421, 1982), and Tootell et al. (Science 218, 902-904, 1982)] leading to the conclusion that the retino-cortical magnification factor cannot be ...
