    • 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 ...
    • Maturana Romesín, Humberto; Frenk, Humberto R. (1963)
      There are ganglion cells in the pigeon retina that respond selectively, some to any edge moving in a particular direction only, others to any vertically moving horizontal edge. This selective response to a specific stimulus ...
    • 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 ...
    • Malacchini Soto, Simoné; Malacchini, Stefania; Benetton, Luciano; Maturana Romesín, Humberto; Dávila, Ximena (Fabrica, 2014)
    • 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 ...
    • Maturana Romesín, Humberto (1991)
    • Maturana Romesín, Humberto (John Wiley and Sons Ltd, 2000)
      We human beings live in the explanations of our existence as living beings. These explanations of our existence include what we call the 'laws of nature'. Though we name them laws, we cannot claim that they have an existence ...
    • Varela, Fancisco G.; Maturana Romesín, Humberto (1970)
      Latencies of the different types of ganglion cell responses to stimulation within a receptive field were measured in guinea pigs. The latency of the response evoked by stimulation of the center or intermediate zone was ...
