“…The patterns resemble those EEG's obtained from day-old chickens (Corner et al, 1967;Peters et al, 1965); they contain a preponderance of behavioral sleep with occasional transitions from sleeping to alert EEG recordings. These same EEG patterns are found in adult quail (Ookawa and Kadono, 1968), except that the mean amplitude of the slow waves is higher in the adult than in the neonate, 200 juV vs. 50 JL/V, and the percentage of alert EEG is increased. In a few records taken in our lab from quail aged 2 to 4 days (data not shown), a noticeable increase in alert EEG was observed with age.…”

A new method for obtaining bipolar electroencephalographic (EEG) recordings from day-old Japanese quail (Coturnix coturnix japonica) is described. The electrodes are chronically placed stainless steel suture wires sewn into the skull and secured with dental acrylic. Using this arrangement, recordings were made over the hyperstriatum accessorum and dorsoarchistriatum regions of the brain. These records showed a preponderance of high amplitude slow waves. Transitions to low amplitude fast waves were also evident, and rare instances of paradoxical sleep were noted. computerized frequency analyses of the recordings divided wave numbers into distinct groups over the 1 to 17 Hz range: 1 to 4 Hz, 4 to 8 Hz, 8 to 13 Hz, and 13 to 17 Hz. Frequencies of waves detectable across the hyperstriatum accessorum were primarily confined to the 1 to 7 Hz range, whereas waves generated around the dorsoarchistriatus showed more abundant high frequency patterns. Mean amplitude of the waves (10 to 50 muV) showed an inverse exponential relationship with frequency. The method described produced an EEG of good quality on unanesthetized birds with the electrode placement procedures requiring less than 30 min.

“…was transiently found in the adult Japanese quail under early stage of intraperitoneal administration of moderately large dose (about SO mg./kg.) of Nembutal (Ookawa and Kadono, 1967). This period was not conspicuous in the adult chicken anesthetized with intravenous injection of Nembutal (Ookawa and Gotoh, 1965).…”

“…In the quail, there was an excited period accompanying both typical behavior and the EEG pattern of slow waves with moderately high amplitude (Ookawa and Kadono, 1967). The chicken did not show remarkably the typical excited behavior after intraperitoneal administration of Nembutal, but we consider that the stage of level-II may correspond to the excited period in the quail.…”

“…Behaviorally, IA is associated with unilateral eye closure in Cetaceans [Lyamin et al, 2001] eared seals and birds [Ball et al, 1988;Rattenborg et al, 1999a, b], with the hemisphere contralateral to the open eye usually showing greater activation when compared to the hemisphere contralateral to the closed eye. In birds, the association between unilateral eye closure and IA has been reported in five species from three orders: domestic chicken (Gallua gallus domesticus) [Spooner, 1964;Peters et al, 1965;Ookawa, 1967]; japanese quail (Coturnix japonica) [Ookawa and Kadono, 1968]; Northern bobwhite (Colinus virginianus) [Amlaner and Ball, 1994]; glaucous-winged gull (Larus glaucescens) [Ball et al, 1985[Ball et al, , 1988; and mallard (Anas platyrhynchos) [Rattenborg et al, 1999a, b]. IA has also been reported in the European blackbird (Turdus merula), but an association between unilateral eye closure could not be established due to the difficulty of observing both eyes simultaneously [Szymczak et al, 1996].…”

Aquatic mammals (i.e., Cetaceans, eared seals and manatees) and birds show interhemispheric asymmetries (IA) in slow-wave sleep-related electroencephalographic (EEG) activity, suggesting that the depth of sleep differs between hemispheres. In birds, an association between unilateral eye closure and IA has been reported in five species from three orders (i.e., Galliformes, Charadriiformes, and Anseriformes). Moreover, unilateral eye closure has been observed during behaviorally defined sleep in 29 species from 13 avian orders, suggesting that birds in general display IA during sleep. Despite the apparent prevalence of unilateral eye closure and IA in birds, previous work did not detect IA in the pigeon, thereby challenging the conclusion that this is a general feature of birds. Using digital period amplitude analysis, an objective method for quantifying EEG power (a measure of wave amplitude) across different frequencies, we demonstrate that pigeons do, in fact, display an association between unilateral eye closure and IA. For a given hemisphere, standardized 2–4 Hz EEG power was greater when the contralateral eye was closed when compared to open. We also found that pigeons used the open eye during IA to monitor their environment. In addition, individual pigeons showed a bias for keeping one eye open more than the other. The direction (left vs. right) of this bias differed across birds, and appeared to be influenced by the structure of the surrounding environment. Finally, with the addition of pigeons (order Columbiformes), IA associated with unilateral eye closure has been recorded in four avian orders, suggesting that this form of sleep is widespread in birds.
