Synchronizing retinal activity in both eyes disrupts binocular map development in the optic tectum.
Spatiotemporal correlations in the pattern of spontaneous and evoked retinal ganglion cell (RGC) activity are believed to influence the topographic organization of connections throughout the developing visual system. We have tested this hypothesis by examining the effects of interfering with these potential activity cues during development on the functional organization of binocular maps in the...
متن کاملSmall-field, binocular neurons in the superficial layers of the frog optic tectum.
Binocular neurons with receptive fields about 5 degrees across were recorded just beneath the pia. Most of them responded to dark stimuli in the lower half of their receptive field and to light stimuli above. There was almost no vertical disparity between the left and right fields and the modal value of the horizontal disparity of the population of cells was 1.7 degrees. Because frogs do not ve...
متن کاملThe Optic Tectum in Fishes
The optic tectum forms the roof of the midbrain and is the primary visual center in fishes. The retina and input from other sensory modalities (auditory, lateral line, somatosensory, electrosensory) are mapped topographically over tectum, where the locations of objects and events in body-centered space are represented. Tectum, via its connections to premotor centers, controls eye movements, app...
متن کاملCoding Schemes in the Archerfish Optic Tectum
Many studies have yielded valuable knowledge on the early visual system but it is biased since the studies have focused on terrestrial mammals alone. Here, to better account for visual systems in different environments and animal classes, we studied the structure of early visual processing in the archerfish which harnesses its extreme visual ability to hunt by shooting water jets at prey hangin...
متن کاملHow the optic tectum stacks up
δ-Protocadherins promote family gettogethers in the developing zebrafish brain. These adhesion proteins help related cells stack up to form columns that are essential for responding to visual stimuli, Cooper et al. reveal (1). In human brains, the visual cortex parses the information streaming in from our eyes. The structure is organized as a series of repeating columns of neurons that radiate ...
