“…How can cold exposure lead animals to increase their consumption of food rich in antioxidants? Being exposed to cold conditions has been described as altering noradrenergic and serotoninergic systems in the brain, thus relecting psychological stress (Stillman et al, 1998;Lapiz-Bluhm et al, 2009). At the same time, cold exposure also alters cerebral oxidative markers, and can result in increased levels of oxidative damage in the brain (Buzadzić et al, 1997;Şahin and Gümüşlü, 2004).…”

Thermal stress leads to increased production of reactive oxygen species. If an organism is not able to simultaneously mount an efficient antioxidant defense system, this may lead to increased oxidative damage, which is potentially deleterious in terms of health and fitness. Exposure to cold or heat is therefore expected to be associated with a high demand for antioxidants. In agreement, several studies have shown that supplementing the diet of thermally stressed organisms with antioxidants leads to a reduction of oxidative damage. However, whether organisms can actively supplement their diet with antioxidants to alleviate temperature-induced oxidative damage is unknown. Here, we show that captive Gouldian finches (Erythrura gouldiae) supplement their diet more with seeds rich in antioxidants below than within their thermoneutral zone. Moreover, having access to seeds rich in antioxidants at temperatures below thermoneutrality decreases their oxidative damage. These results indicate that, when facing a thermal challenge, animals are able to take advantage of the antioxidant properties of their food to improve their oxidative balance. Having access to food resources rich in antioxidants may therefore be of primary importance for organisms in their natural habitat, as it may help them to cope with oxidative constraints due to challenging temperature regimes.

“…Also, it needs to be recognized that at least some feed restriction was needed presently to increase food drive during RAM testing; otherwise, the use of ad libitum-fed birds at testing would have likely been met with much less or no motivation by the test subjects to consume the feed pellet rewards when traveling down the arms of the RAM. Pre-RAM food or water, or both, restriction protocols similar to the protocol we presently used are well documented in the literature for RAM studies (Stillman et al, 1998).…”

“…In addition, Satterlee and Marin (2006) found that control quail of the LS line that were simply captured and transported to an open field showed a higher mean ambulation rate, less freezing behavior, and increased numbers of floor sectors entered than did HS controls and LS and HS quail stressed by 5 min of immobilization before testing. Finally, in rats, a precedent study that demonstrates short-term memory reduction after brief nor-mothermic restraint treatment using a RAM has been done (Stillman et al, 1998). Indeed, this study, which prompted our present work and from which we modeled our present treatments, showed that 15 min of normothermic restraint treatment decreased the number of correct entries into baited RAM arms out of the first 8 choices made (NUMCOR8) and the total number of RAM arm choices (TOTCHOICES) responses while increasing the time required to make a choice (TIME/ CHOICE) response in RAM-tested rats.…”

“…It is well known that certain regions of the hippocampus of both mammals and birds are involved in various aspects of learning and spatial memory and that the hippocampus can be damaged via the action of glucocorticoid (GC) hormones associated with stress situations that often result in transient (acute stressinduced) or permanent (chronic stress-induced) impaired cognition (Dachir et al, 1993;Levy et al, 1994;Endo et al, 1996;McEwen et al, 1997;McLay et al, 1998;Stillman et al, 1998;Diamond et al, 1999;Rose, 2000;Kitaysky et al, 2003;Sandstrom and Hart, 2005;Montaron et al, 2006;Hodgson et al, 2007;He et al, 2008). Indeed, many researchers ascribe to the wellestablished GC cascade hypothesis of brain aging and neurodegeneration that suggests chronic high levels of corticosteroids or stressful events, or both, underlie accelerated age-dependent hippocampal neuron degeneration (Landfield et al, 1978;Sapolsky et al, 1986;Kerr et al, 1991;Landfield and Eldridge, 1991;McEwen et al, 1997;He et al, 2008).…”

Short-term spatial memory responses in aged Japanese quail selected for divergent adrenocortical stress responsiveness

Stress-induced glucocorticoids can dampen learning and spatial memory via neuronal damage to the hippocampus. Cognition losses can be transient (associated with acute stress episodes) or permanent as in aged individuals who show chronic glucocorticoid-induced accelerated brain aging and neurodegeneration (dementia). Thus, chronic versus acute stress effects on spatial memory responses of quail selected for reduced (low stress, LS) or exaggerated (high stress, HS) plasma corticosterone (B) response to brief restraint were assessed. Aged food-motivated male LS and HS quail were tested for 10 min in a feed-baited 8-arm radial arm maze (RAM) 1) at 255 d of age (quail who had experienced lifelong management stressors but who were otherwise never intentionally stressed; that is, chronically stressed birds), 2) on the next day post-acute stressor treatment (5 min of restraint), and 3) on the next day without treatment (acute stress recovery). The RAM tests used the win-shift procedure in which visited arms were not rebaited. Radial arm maze performance was measured by determination of the total number of arm choices made, the number of correct entries made into baited arms out of the first 8 choices, the time required to make a choice, and the number of pellets eaten. Line effects (P < 0.001 in all cases) were detected for total number of arm choices made (HS < LS), number of correct entries made into baited arms out of the first 8 choices (HS < LS), time required to make a choice (HS > LS), and number of pellets eaten (HS < LS). However, neither the effects of day of RAM testing nor its interaction with line further influenced these variables. Thus, although selection for divergent plasma B responsiveness to an acute stressor was found to be associated with severe impairment of spatial memory in aged male HS compared with LS quail, the observed spatial memory impairments (HS > LS) could not be further altered by acute stressor treatment. Line differences in cognition may reflect lifelong management-induced stress episodes that periodically produce higher plasma B responses in HS than LS quail, which underlie HS quail memory deficits, or other etiologies, or both.
