Abstract

The EEG and EMG of two groups of chicks (Gallus domesticus), (an experimental one who was imprinted, and a control one who was not), were recorded during 3 hours before and 3 hours after imprinting. The fertilized eggs were kept in an incubator under controlled temperature and humidity until ecclosion occurred. The recording session began 10 hours after ecclosion and after two hours of habituation to the recording conditions. During the imprinting session, E group met a natural stuffed white hen moved by a slow motor. The total amount of time spent in paradoxical sleep (PS), as well as the number of PS episodes increased significantly following imprinting in the E group. Opposite results were found in C group: total amount and number of PS episodes decreased significantly after the pseudo-imprinting session. Neither slow wave sleep, nor wakefulness were modified.

The Role of Sleep in Song Learning Processes in Songbird
2019, Handbook of Behavioral Neuroscience
Citation Excerpt :
Also, REM sleep seems to be a critical feature of their imprinting behavior (a general form of learning during which a naive juvenile learns to recognize the first moving individual or object seen). Domestic chicks express more REM sleep episodes after the imprinting (Solodkin, Cardona, & Corsi-Cabrera, 1985). Sleep in birds as in mammals influences the process of memory stabilization or consolidation (Bolhuis & Moorman, 2015; Brawn & Margoliash, 2014; Walker & Stickgold, 2004), as demonstrated by several studies carried out not only in songbirds but also in nonsongbird species.
Songbirds are a unique model to study language development in humans. Birdsong, as human language, is acquired through complex vocal learning processes during which individuals learn to modify their vocalizations, song in songbirds and language in humans, by imitating surrounding individuals. Both birdsong and human speech rely on a complex sensorimotor integration during which the auditory feedback provided by the perception of one's own vocalizations produced is monitored and contrasted to the memorization of vocal sounds to adapt the vocal motor commands. Birdsong is under the control of a set of dedicated brain areas, and researches in the last decades have identified some neurobiological mechanisms involved during song learning and song production. As such, songbirds offer a unique opportunity to investigate the neurobiological mechanisms underlying their singing behavior and better understand the role of sleep in learning, especially in vocal learning.
Neural mechanisms of vocal imitation: The role of sleep replay in shaping mirror neurons
2017, Neuroscience and Biobehavioral Reviews
Citation Excerpt :
In the non-songbird domestic chick, consolidation of a memory for an imprinting stimulus requires sleep within a restricted period shortly after learning (Jackson et al., 2008). Moreover, imprinted chicks exhibit more REM sleep than non-imprinted chicks during the subsequent hours of sleep (Solodkin et al., 1985). In starlings (Sturnus vulgaris), a songbird species, sleep has been reported to provide protection against interference impairment (Brawn et al., 2013).
Learning by imitation involves not only perceiving another individual’s action to copy it, but also the formation of a memory trace in order to gradually establish a correspondence between the sensory and motor codes, which represent this action through sensorimotor experience. Memory and sensorimotor processes are closely intertwined. Mirror neurons, which fire both when the same action is performed or perceived, have received considerable attention in the context of imitation. An influential view of memory processes considers that the consolidation of newly acquired information or skills involves an active offline reprocessing of memories during sleep within the neuronal networks that were initially used for encoding. Here, we review the recent advances in the field of mirror neurons and offline processes in the songbird. We further propose a theoretical framework that could establish the neurobiological foundations of sensorimotor learning by imitation. We propose that the reactivation of neuronal assemblies during offline periods contributes to the integration of sensory feedback information and the establishment of sensorimotor mirroring activity at the neuronal level.
Sleep and memory in mammals, birds and invertebrates
2015, Neuroscience and Biobehavioral Reviews

Such contribution is suggested, for example, by the fact that REM sleep seems to be a prevalent sleep stage during early development not only in mammals but also in birds (Scriba et al., 2013). However, presently clear evidence for an involvement of REM sleep in filial imprinting is missing (Solodkin et al., 1985). To summarize, sleep is of critical importance for the formation of long-term imprinting memory in chicks.
Sleep supports memory consolidation. Based on studies in mammals, sleep-dependent consolidation has been conceptualized as ‘active system consolidation’. During waking, information is encoded into an initial store (hippocampus). During subsequent sleep, some of the newly encoded memories are selected to be reactivated and redistributed toward networks serving as long-term store (e.g., neocortex), whereby memories become transformed into more general, schema-like representations. Here we asked whether sleep in non-mammalian species might play a comparable role for memory. The literature review revealed that sleep produces enhancing effects on memory in all non-mammalian species studied. Furthermore, across species some of the hallmarking features of active system consolidation were identified: Studies of filial imprinting in chicks suggest that a redistribution of imprinting memory toward long-term storage sites occurs during sleep; song learning in birds appears to be driven by reactivations of song representations during sleep; studies of bees demonstrated the selectivity of sleep-dependent consolidation, benefiting extinction but not original classical conditioning. Although overall fragmentary, first evidence in non-mammalian species suggests active system consolidation might be an evolutionary conserved function of sleep.
Variation in sleep behaviour in free-living blue tits, Cyanistes caeruleus: Effects of sex, age and environment
2010, Animal Behaviour
Although sleep is fundamental for survival, not much is known about sleep behaviour in free-living animals and between-individual variation in sleep patterns has hardly been studied, except in humans. We analysed sleep behaviour in a free-living population of blue tits in southern Germany. We recorded individuals roosting in nestboxes between November and April using infrared-sensitive cameras. We investigated the following sleep parameters: time of entering and leaving the nestbox, sleep onset, awakening time, sleep duration, midpoint of sleep, latency to sleep and frequency and duration of nocturnal awakenings. Sleep onset, awakening time and sleep duration followed seasonal changes in daylength. Blue tits slept ca. 4.8 h longer in winter than in spring. During the night, birds woke up between 23 and 230 times, but this did not change seasonally. Local light conditions influenced awakening time: birds at brighter locations woke up earlier. Females slept on average 15 min longer per night than males and this sex difference became more pronounced in early spring. Although females spent a greater proportion of the night awake than males, they still slept more overall. First-year birds spent more time in the nestbox after waking up and left the nestbox later in the morning than older individuals. Repeatability estimates showed that individuals were consistent in their sleep behaviour over the 2-year study period. Our results indicate that sleep patterns are individual-specific traits in blue tits. We suggest that the observed sex difference in sleep duration is caused by sexual selection.
History and future of comparative analyses in sleep research
2009, Neuroscience and Biobehavioral Reviews
The comparative methods of evolutionary biology are a useful tool for investigating the functions of sleep. These techniques can help determine whether experimental results, derived from a single or few species, apply broadly across a specified group of animals. In this way, comparative analysis is a powerful complement to experimentation. The variation in the time mammalian species spend asleep has been most amenable for use with this approach, given the large number of mammals for which sleep data exist. Here, it is assumed that interspecific variation in the time spent asleep reflects underlying differences in the need for sleep. If true, then significant predictors of sleep times should provide insight into the function of sleep. Many such analyses have sought the evolutionary determinants of mammalian sleep by relating the time spent in the two basic states of sleep, rapid eye movement (REM) and non-REM sleep, to constitutive variables thought to be functionally related to sleep. However, the early analyses had several methodological problems, and recent re-analyses have overturned some widely accepted relationships, such as the idea that species with higher metabolic rates engage in more sleep. These more recent studies also provide evolutionarily broad support for a neurophysiological role for REM sleep. Furthermore, results from comparative analyses suggest that animals are particularly vulnerable to predation during REM sleep, a finding that lends further support to the notion that REM sleep must serve an important function. Here, we review the methodology and results of quantitative comparative studies of sleep. We highlight important developments in our understanding of the evolutionary determinants of sleep and emphasize relationships that address prevailing hypotheses for the functions of sleep. Lastly, we outline a possible future for comparative analyses, focusing on work in non-mammalian groups, the use of more physiologically meaningful variables, and electrophysiological sleep studies conducted in the wild.
A behavioural study of sleep patterns in the malachite sunbird, Cape white-eye and fan-tailed widowbird
2009, Animal Behaviour
The function of sleep in birds is poorly understood, even though birds spend a large part of their lives sleeping. Sleep behaviour in passerine birds has not been looked at as extensively as that of nonpasserine birds. We looked at the sleep behaviour of three passerine birds occurring in southern Africa, namely the malachite sunbird, Nectarinia famosa, the Cape white-eye, Zosterops virens, and the fan-tailed widowbird, Euplectes axillaris. By using an infrared-sensitive camera, we recorded basic sleep behaviour, at various ambient temperatures, of all three species, such as sleep position and eye closure. We also investigated the incidence, or lack thereof, of unihemispheric sleep. Individuals of all three species spent most of the night asleep and woke up intermittently throughout the night, with no significant differences between temperatures. Cape white-eyes and malachite sunbirds showed an increase in back sleep and a decrease in front sleep at 5 °C. Little evidence of unihemispheric sleep was found, suggesting that it is more likely to occur in nonpasserines.
