“…Such quantifications have included differences in time spent in the proximity of the imprinted object (Yamaguchi et al, 2012), differences in locomotion toward the imprinted and novel stimulus (Bolhuis et al, 2000), differences in locomotion during the presentation of imprinted and novel objects and the absence of a stimulus (Maekawa et al, 2006), and number of chickens within a group selecting the imprinted stimulus over several trials (Wallhäusser and Scheich, 1987). In this study, we normalized differences between locomotion to novel and imprinted stimuli by the average baseline locomotion in the wheel when no stimulus was presented.…”

The formation of imprinted memories during a critical period is crucial for vital behaviors, including filial attachment. Yet, little is known about the underlying molecular mechanisms. Using a combination of behavior, pharmacology, in vivo surface sensing of translation (SUnSET) and DiOlistic labeling we found that, translational control by the eukaryotic translation initiation factor 2 alpha (eIF2α) bidirectionally regulates auditory but not visual imprinting and related changes in structural plasticity in chickens. Increasing phosphorylation of eIF2α (p-eIF2α) reduces translation rates and spine plasticity, and selectively impairs auditory imprinting. By contrast, inhibition of an eIF2α kinase or blocking the translational program controlled by p-eIF2α enhances auditory imprinting. Importantly, these manipulations are able to reopen the critical period. Thus, we have identified a translational control mechanism that selectively underlies auditory imprinting. Restoring translational control of eIF2α holds the promise to rejuvenate adult brain plasticity and restore learning and memory in a variety of cognitive disorders.DOI: http://dx.doi.org/10.7554/eLife.17197.001

“…A sensitive (critical) period for imprinting in domestic chicks is well-documented242526272829, and stress vulnerability develops during early susceptible periods in rodent models35. Thus, we examined the existence of a sensitive period of social attachment formation by focusing on four typical behaviour markers (g-move, active approach (aa), freezing, and escape) (Figure 3).…”

“…Nakamori et al28. used visual imprinting toward the computer-generated geometrical images29, whereas in this study, the real chick was used and not only visual stimuli, but also acoustic and somatosensory cues were integrated to develop social affiliation. However, there is a need to clarify precise neuronal substrate for social affiliation toward chicks before we can answer the difference of the ending of the critical period for the imprinting and the question about the nature of social affiliation learning compared with the classical imprinting.…”

Attachment formation is the most pivotal factor for humans and animals in the growth and development of social relationships. However, the developmental processes of attachment formation mediated by sensory-motor, emotional, and cognitive integration remain obscure. Here we developed an animal model to understand the types of social interactions that lead to peer-social attachment formation. We found that the social interaction in a sensitive period was essential to stabilise or overwrite the initially imprinted peer affiliation state and that synchronised behaviour with others based on common motivations could be a driver of peer social attachment formation. Furthermore, feeding experience with supplementation of ubiquinol conferred peer social attachment formation even after the sensitive period. Surprisingly, the experience of feeding beyond the cage window was also effective to reduce the required amount ubiquinol, suggesting that peri-personal space modulation may affect socio-emotional cognition and there by lead to attachment formation.

“…Colours are crucial to discriminate between individuals in a chicken flock (Guhl & Ortman, 1953). In filial imprinting, it has also been described to be an essential characteristic used by the young animal to recognize their artificial objects (Maekawa et al, 2006). Some colours are more effective than others in imprinting (Bolhuis, 1991).…”

Filial imprinting has become a model for understanding memory, learning and social behaviour in neonate animals. This fast attachment mechanism allows the young of precocial bird species to learn the characteristics of conspicuous visual stimuli and display affiliative response to them. Although more prolonged exposure to an object produces a stronger preference for it afterwards, this relation is not linear. Chicks can even prefer to approach novel rather than familiar objects at some stages of imprinting. The time course and stability of imprinting has just started to be investigated. To date, little is known about how filial preferences develop across time, due to the challenges in assessing individual performance. This study aimed to investigate filial preferences for familiar and novel imprinting objects over time. We have used an automated setup to track the behaviour of chicks continuously for subsequent days. After hatching, chicks were individually placed in an arena where stimuli were displayed on two opposite screens. The duration of exposure and the type of stimuli were manipulated while the time spent at the imprinting stimulus was monitored across six days. We showed that prolonged exposure (3 days vs 1 day) to a stimulus produced robust filial imprinting preferences. Interestingly, with a shorter exposure (1 day), animals re-evaluated their filial preferences in functions of their innate preferences and past experiences. Our study suggests that predispositions influence learning when the imprinting memories are not fully consolidated, driving animal preferences toward more predisposed stimuli.
