TLDR
Although the cells in the pigeon's optic tectum seem to be preferentially stimulated by moving objects, directional selectivity appears to be a characteristic of the superficial tectal layers.About:

Journal ArticleDOI
Computation of different optical variables of looming objects in pigeon nucleus rotundus neurons.
TL;DR: Three types of looming-selective neurons have been found in the nucleus rotundus of pigeons, each computing a different optical variable related to image expansion of objects approaching on a direct collision course with the bird.
Journal ArticleDOI
Organization of the tectofugal visual pathway in the pigeon: a retrograde transport study.
TL;DR: To examine the detailed organization of this principal ascending visual pathway, small injections of the marker horseradish peroxidase were placed in various sites throughout the ectostriatum (E) or nucleus rotundus (Rt) in pigeons, indicating the tectofugal pathway to be comprised of at least five different channels.
Journal ArticleDOI
The specification of the retino-tectal projection in the chick.
TL;DR: In the chick, as in Xenopus, there is a clear temporal co‐incidence between the withdrawal of the first ganglion cells from the cell‐cycle and the establishment of the topographic specification of the retino‐tectal projection.
Journal ArticleDOI
Visual processing in pigeon nucleus rotundus: Luminance, color, motion, and looming subdivisions
TL;DR: The responses of single cells to luminance, color and computer-generated spots, bars, kinematograms, and motion-in-depth stimuli were studied in the nucleus rotundus of pigeons and indicate that visual information processing of color, ambient illumination, andmotion in depth are segregated into different subdivisions at the level of nucleus rotundaus in the avian brain.
Journal ArticleDOI
Control from below: the role of a midbrain network in spatial attention
TL;DR: The role of the midbrain network in controlling attention, the neural circuits that support this role and current knowledge about the computations performed by these circuits are discussed.

Receptive fields, binocular interaction and functional architecture in the cat's visual cortex
David H. Hubel,Torsten N. Wiesel +1 more
TL;DR: This method is used to examine receptive fields of a more complex type and to make additional observations on binocular interaction and this approach is necessary in order to understand the behaviour of individual cells, but it fails to deal with the problem of the relationship of one cell to its neighbours.

Receptive fields and functional architecture in two nonstriate visual areas (18 and 19) of the cat.
David H. Hubel,Torsten N. Wiesel +1 more
TL;DR: To UNDERSTAND VISION in physiological terms represents a formidable problem for the biologist, and one approach is to stimulate the retina with patterns of light while recording from single cells or fibers at various points along the visual pathway.
Journal ArticleDOI
Discharge patterns and functional organization of mammalian retina
TL;DR: The Limulus preparation shows many features which are similar to other simple sense organs, for instance, stretch receptors, however, instead of photochemical events, stretch-deformation acts as the adequate stimulus on sensory terminals and is translated into a characteristic discharge pattern.

Spatial and chromatic interactions in the lateral geniculate body of the rhesus monkey.
Torsten N. Wiesel,D. H. Hubel +1 more
TL;DR: The opponent principle, in which spatially separated excitatory and inhibitory regions are pitted against each other, has now been observed for retinal ganglion cells in the frog, the lizard, the rabbit, the rat, the ground squirrel, and the monkey.
