The effect of a high ( @entity6353 ) versus low fat/sugar (chow) food on a conditioned-place-preference (CPP) task was evaluated in marmoset monkeys. Anxiety-related behaviors and @entity701 levels before and after the CPP task were also measured. Subjects were habituated to a two-compartment CPP box and then, on alternate days, had access to only one compartment during daily 15-min conditionings, for a total of 14 trials. Marmosets were provisioned with @entity6353 chips in the CC-paired compartment on odd-numbered trials and standard chow in the CW-paired compartment on even-numbered trials. They were then tested for preferring the CC-paired context after a 24-h interval. During the conditioning, a significantly greater amount (in kcal/trial) of @entity6353 was consumed than chow, yet the foraging pattern of both food types was similar. On the test trial, the time spent in the CC-paired context increased significantly compared to pre-CPP levels, yet this response was not readily predicted by baseline behavioral or @entity701 levels. Also, the @entity6353 CPP response was positively correlated with foraging time, rather than the amount of calories consumed. The sudden absence of the food increased exploration, while the @entity6353 CPP effect was associated with vigilance - both @entity146 in marmosets. This behavioral profile occurred regardless of any concomitant change or correlation with @entity701 . Therefore, the high fat/sugar food was more prone to be overly consumed by the marmosets, to induce a CPP response and to lead to anxiety-related behavior in its absence.

High versus low fat/sugar food affects the behavioral, but not the XXXX response of marmoset monkeys in a conditioned-place-preference task.
