| dc.description.abstract1 | Temporal information about food availability can be easily entrained, as in the case of
fixed feeding routines of captive animals. A sudden unintentional or deliberate delay (e.g.,
food deprivation—FD) leads to frustration and psychological stress due to the loss of
temporal predictability. How marmosets—an increasingly used small primate—process
and respond to FD stress has not been previously assessed. Here we delayed the
routine feeding of adult captive marmosets for 3 or 6 h. Blood cortisol concentration
was used as a hormonal measure of the stress response. Changes in the left/right
baseline tympanic membrane temperature (TMT) were used as an indirect ipsilateral
indicator of hemisphere activity. Marmosets that were deprived for 3 h had higher cortisol
levels than non-deprived controls. Cortisol concentration in the marmosets deprived for
6 h did not differ from controls possibly due to adaptative mechanisms against the
detrimental effects of prolonged high cortisol levels. Interestingly, FD stress may have
been processed more symmetrically at first, as indicated by the bilateral increase in TMT
at the 3 h interval. As the event progressed (i.e., 6 h), a clear rightward TMT bias suggests
that hemisphere activity had become asymmetrical. Therefore, the sudden loss of
temporal predictability of an entrained routine feeding schedule induces time-dependent
changes in the cortisol stress response and shifts in the TMT (and potentially hemisphere
activity) lateralization bias of adult captive marmosets. | pt_BR |
