Lateralisation of short- and long-term visual memories in an insect
The formation of memories within the vertebrate brain is lateralised between hemispheres across multiple modalities, however, in invertebrates evidence for lateralisation is restricted to olfactory memories, primarily from social bees. Here we use a classical conditioning paradigm with a visual conditioned stimulus to show that visual memories are lateralised in the wood ant, Formica rufa. We show that a brief contact between a sugar reward and either the right or left antenna (reinforcement) is sufficient to produce a lateralised memory, even though the visual cue is visible to both eyes throughout training and testing. Reinforcement given to the right antenna induced short-term memories whereas reinforcement given to the left antenna induced long-term memories. Thus, short- and long-term visual memories are lateralised in wood ants. This extends the modalities across which visual memories are lateralised in insects and suggests that such memory lateralisation may have evolved multiple times, possibly linked to the evolution of eusociality in the Hymenoptera.

Data from: Effects of elevated carbon dioxide on male and female behavioural lateralisation in a temperate goby
Behavioural abnormality in fishes has been proposed as a significant threat of the increasing levels of carbon dioxide occurring in the oceans. Negative effects of elevated CO2 have been reported for behaviours such as predator-prey interactions, foraging, hearing and behavioural lateralisation. Importantly, the effects vary greatly both within and between species, and some recent studies have shown minimal effects of CO2 on behaviour. Whether the effect of CO2 also varies between males and females is however virtually unexplored. According to resource allocation theory, females are expected to be more sensitive to elevated CO2, meaning that non-sex specific studies may overlook ecologically important differences between the sexes. In this study, we investigated the possible differences between males and females in their response to elevated CO2 by performing behavioural lateralisation tests in adult temperate two-spotted gobies Gobiusculus flavescens. We found that the strength of the side bias (absolute lateralisation) was unaffected by the CO2 treatment, and there was no difference between males and females. The control fish were slightly right-biased in their behavioural asymmetry (mean relative lateralisation of 14). Exposure to high CO2 affected this pattern, such that treated fish were slightly left biased (mean relative lateralisation of -10), regardless of their sex. The same results were obtained yet again when the study was repeated during a second year. We discuss our results in light of the great variation in lateralisation that has been reported to depend on variables such as species, ecological settings and environmental factors.
Data from: Lateralisation correlates with individual differences in inhibitory control in zebrafish
<p class="MsoNoSpacing"><span><span><span><span><span><span><span><span><span><span><span>The study investigated the relationship between cerebral lateralisation and inhibitory control in zebrafish. Lateralisation was assessed using a mirror test. Fish were observed in an apparatus with mirror walls and eye preference for observing the mirror image was recorded. This preference was used to calculate the relative and the absolute lateralisation index. Inhibitory control was assessed using a foraging task. Fish were exposed to live prey enclosed inside a transparent tube. The number of attacks and its reduction over time were used as measures of inhibition.</span></span></span></span></span></span></span></span></span></span></span></p>
