Influence of prenatal pre-exposure to an odor on intake behavior of an aversive solution in newborn rats
(Elsevier Ireland, 2018-04)
Early pre- or postnatal sensory experiences significantly influence flavor preference and food intake, and can induce liking for innately unpalatable flavors. Previous work found that newborn rats stimulated with an odor ...
Odor Learning and Its Experience-Dependent Modulation in the South American Native Bumblebee Bombus atratus (Hymenoptera: Apidae)
(Frontiers Media SA, 2018-04)
Learning about olfactory stimuli is essential in bumblebees' life since it is involved in orientation, recognition of nest sites, foraging efficiency and food yield for the colony as a whole. To evaluate associative learning ...
Maternal odor exposure modulates acceptance of a bitter taste in newborn and infant rats
(Frontiers Media S.A., 2018-07)
The acceptance of bitter, aversive, substances during early life is enhanced by stimulation with familiar, pre-exposed odors. Newborn rats exhibited heightened grasp responses toward an artificial nipple dispensing quinine, ...
Interoceptive Insular Cortex Mediates Both Innate Fear and Contextual Threat Conditioning to Predator Odor
(2019)
The insular cortex (IC), among other brain regions, becomes active when humans experience fear or anxiety. However, few experimental studies in rats have implicated the IC in threat responses. We have recently reported ...
Sensitive period for the acceptance of unpalatable flavors in the presence of a preexposed odor in infant rats
(John Wiley & Sons Inc, 2020-12)
It has been shown that exposure to familiar odors facilitate the acceptance of bitter flavors in preweanling rats, yet it unknown how long this phenomenon persists. This study assessed, in 9- or 15-day-old Wistar rats, the ...
Change in the hedonic value of an aversive stimulus in the presence of a pre-exposed odor
(Pergamon-Elsevier Science Ltd, 2014-09)
Rats exhibit a sensitive period from the time of birth until postnatal day 10 during which they develop preferences for odors even if those odors are paired with a moderately aversive stimulus. It is still unknown whether ...
Interoceptive Insular Cortex Mediates Both Innate Fear and Contextual Threat Conditioning to Predator Odor
(FRONTIERS MEDIA SA, 2020)
The insular cortex (IC), among other brain regions, becomes active when humans experience fear or anxiety. However, few experimental studies in rats have implicated the IC in threat responses. We have recently reported ...
Learning experiences comprising central ethanol exposure in rat neonates: Impact upon respiratory plasticity and the activity of brain catalase
(Elsevier Science Inc, 2020-11)
Fetal ethanol exposure represents a risk factor for sudden infant death syndrome, and the respiratory effects of fetal ethanol exposure promote hypoxic ischemic consequences. This study analyzes central ethanol's effects ...
Learning experiences comprising central ethanol exposure in rat neonates: Effects upon respiratory plasticity and the brain catalase system
(Dougmar Publishing Group, 2019)
Fetal ethanol (EtOH) exposure represents a risk factor for the Sudden Infant Death Syndrome and it’s early effects upon respiration also promotes hypoxic ischemic consequences. This study analyzes central ethanol’s effects ...
Brief ethanol exposure and stress-related factors disorganize neonatal breathing plasticity during the brain growth spurt period in the rat
(Springer, 2018-04)
Rationale: The effects of early ethanol exposure upon neonatal respiratory plasticity have received progressive attention given a multifactorial perspective related with sudden infant death syndrome or hypoxia-associated ...
