Lack of interocular transfer of pattern discrimination learning in chicks

Lateralized Interhemispheric Transfer of Color Cues: Evidence for Dynamic Coding Principles of Visual Lateralization in Pigeons

“…Analogous to IOT results in pigeons, there are dissenting findings in chicks caused by procedural variations within experimental designs. IOT was successful in a pattern-discrimination task when rewarded with food (Gaston, 1984), but not when reinforced with warm air (Gaston, 1979). This very short overview shows that cerebral asymmetries but also a multitude of further variables determine if interhemispheric transmission occurs.…”

Swapping mallards: monocular imprints in ducklings are unavailable to the opposite eye

“…Thus, the content of visual imprinting from one eye did not 406 drive behaviour guided by a contralateral naïve eye, at least within three hours. This is 407 probably due to lack of interhemispheric information transfer, and places the visual 408 behaviour of newborn mallards within the model proposed for some other adult birds, 409 including pigeons and chickens (Gaston, 1979;1984;Diekamp et al, 1999;Manns and 410 Römling, 2012;Martinho et al, 2015), and possibly marsh tits (Sherry et al, 1981;411 Clayton, 1993;Clayton and Krebs, 1994). 412…”

“…Experiments in marsh tits 70 (Poecile palustris) have shown that food cached with one eye open is not found when 71 searching with the other (Sherry et al, 1981), but that information gathered with the left 72 eye system is apparently transferred to long term memory in the right eye system 73 between three and 24 hours following learning (Clayton, 1993). Incomplete contralateral 74 visual input has been demonstrated in local area homing in pigeons (Columba livia) 75 (Martinho et al, 2015), and interhemispheric transfer of pattern discrimination fails in 76 chickens (Gallus gallus) (Gaston, 1979), though in the latter case, reinforcement with 77 food enabled previously failed transfer (Gaston, 1984). This lack of complete access to 78 the other hemisphere's visual memories has produced a similar pattern in binary 79 discrimination and transitive inference tasks in pigeons (Diekamp et al, 1999;Manns and 80 Römling, 2012).…”

Interhemispheric transfer of visual discriminations in split-chiasm monkeys (Macaca nemestrina) and its measurement.

“…Interhemispheric transfer of learned visual discriminations appears to be essentially absent in the rabbit ( van Hof, 1970;van Hof & van der Mark, 1976;Vos-Korthals & van Hof, 1988), and adroit experimentation was needed for its demonstration in the chick (Gaston, 1979(Gaston, , 1984. However, with both the rat (Sheridan, 1965) and the goldfish (Yeo, 1979), good abilities to transfer visual discriminations interhemispherically have been found.…”
