“…Furthermore, an interesting hypothesis about the left nostril use during sniffing at human sweat collected during a fear situation and physical stress is that these heterospecific chemosignals (probably produced during the escape behavioural response to a predator) could elicit dogs' prey drive (i.e., approaching behavioural tendencies) to the stimuli through the selective activation of the left hemisphere. The evidence that, in dogs [36], as in other animal models (e.g., toads [34] and birds [33]), neural structures on the left side of the brain are involved in the control of predatory behaviour supports this hypothesis.…”

“…Furthermore, a shift from the right to the left nostril use was observed with repeated stimulus presentations, indicating the prevalent control of sniffing behaviour by the left hemisphere when routine responses to odour stimuli emerge as a result of familiarization [1,2,30,31]. Left hemisphere specialisation in routine tasks has been observed in pigeons [32], wild stilts [33], toads [34] and chickens [35]. In the latter case, during a routine task of finding food, chicks using the right eye (left hemisphere) and not the left eye learn to find food grains scattered on a back-ground of distracting pebbles (similar to the grains).…”

Understanding the complementary specialisation of the canine brain has been the subject of increasing scientific study over the last 10 years, chiefly due to the impact of cerebral lateralization on dog behaviour. In particular, behavioural asymmetries, which directly reflect different activation of the two sides of the dog brain, have been reported at different functional levels, including motor and sensory. The goal of this review is not only to provide a clear scenario of the experiments carried out over the last decade but also to highlight the relationships between dogs' lateralization, cognitive style and behavioural reactivity, which represent crucial aspect relevant for canine welfare.

“…For example, toads, lizards and birds show more aggression towards conspecifics on their left side than their right [7][8][9]. Feeding responses, on the other hand, are often, but not always, biased towards the right [10][11][12][13][14]. Individuals within & 2016 The Author(s) Published by the Royal Society.…”

At odds with the group: changes in lateralization and escape performance reveal conformity and conflict in fish schools

et al. 2016

Many vertebrates are known to show behavioural lateralization, whereby they differentially use one side of their body or either of their bilateral organs or limbs. Behavioural lateralization often manifests in a turning bias in fishes, with some individuals showing a left bias and others a right bias. Such biases could be the source of considerable conflict in fish schools given that there may be considerable social pressure to conform to the group to maintain effective group evasion. Here, we show that predation pressure is a major determinant of the degree of lateralization, both in a relative and absolute sense, in yellow-and-blueback fusiliers (Caesio teres), a schooling fish common on coral reefs. Wild-caught fish showed a bias for right turning. When predation pressure was experimentally elevated or relaxed, the strength of lateralization changed. Higher predation pressure resulted in an increase in the strength of lateralization. Individuals that exhibited the same turning bias as the majority of individuals in their group had improved escape performance compared with individuals that were at odds with the group. Moreover, individuals that were right-biased had improved escape performance, compared with left-biased ones. Plasticity in lateralization might be an important evolutionary consequence of the way gregarious species respond to predators owing to the probable costs associated with this behaviour.

“…Lateralized eye use has been observed in a wide variety of vertebrate species, including mammals (Braccini, Lambeth, Schapiro, & Fitch, 2012;Guo, Meints, Hall, Hall, & Mills, 2009;Racca, Guo, Meints, & Mills, 2012;Smith, Proops, Grounds, Wathan, & McComb, 2016;Versace, Morgante, Pulina, & Vallortigara, 2007), birds (Martinho, Burns, Von Bayern, & Kacelnik, 2014;McKenzie, Andrew, & Jones, 1998;Rogers, 2012;Ventolini et al, 2005;Zucca & Sovrano, 2008), reptiles (Bonati & Csermely, 2011;Hews & Worthington, 2001;Robins, Chen, Beazley, & Dunlop, 2005), amphibians (Vallortigara, Rogers, Bisazza, Lippolis, & Robins, 1998), and fish (Bisazza, De Santi, & Vallortigara, 1999;Bisazza, Facchin, Pignatti, & Vallortigara, 1998;Karenina, Giljov, & Malashichev, 2013). In vertebrates, the right brain hemisphere (which processes information obtained by the left eye) is thought to control emotions and spatial perception, while the left hemisphere (right eye) is responsible for attention, perceptual processing and the control of motor responses (Rogers, Vallortigara, & Andrew, 2013;Vallortigara, Chiandetti, & Sovrano, 2011).…”

Lateralized eye use is thought to increase brain efficiency, as the two hemispheres process different information perceived by the eyes. It has been observed in a wide variety of vertebrate species and, in general, information about conspecifics appear to elicit a left eye preference whilst information about prey elicits the opposite. In reptiles, this phenomenon has only been investigated using live conspecifics in agonistic contexts, and so it is not clear whether it can be found when using video stimuli. Here, bearded dragons (Pogona vitticeps) were presented with videos of female conspecifics and prey that either moved or were stationary, along with a control video of an empty background.Females exhibited a left eye bias towards conspecifics but males did not, however, both sexes looked at conspecifics significantly longer than prey. Further, animals used their left eye significantly longer when viewing moving stimuli of both categories. These results suggest that, in lizards, lateralized eye use when viewing conspecifics may be controlled by sex, and strongly influenced by stimulus movement. This study therefore provides important insights into the role of lateralized processing in lizard perception, and sets the scene for future work investigating the role of sex on perception of conspecifics and the role of motion in lateralized eye use.
