Behavioral responses to emotional challenges in female rats living in a seminatural environment: The role of estrogen receptors
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-11-06)
Estrogen receptors (ERs) are involved in sexual as well as non-sexual behaviors. In the present study we assessed the effects of stimuli inducing positive or negative affect on sociosexual, exploratory and fear-related behaviors of female rats housed in groups (4 females, 3 males) in a seminatural environment. Ovariectomized females were treated with oil, 17β‑estradiol benzoate (EB, 18 μg/kg), the ...
Action-associated modulation of visual event-related potentials evoked by abstract and ecological stimuli
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-09-19)
This study investigated the influence of action‐associated predictive processes on visual ERPs. In two experiments, we sought evidence for sensory attenuation (SA) indexed by ERP amplitude reductions for self‐induced stimuli when compared to passive viewing of the same images. We assessed if SA is (a) present for both ecological and abstract stimuli (pictures depicting hands or checkerboards), (b) ...
Manual dexterity in young and healthy older adults. 1. Age- and gender-related differences in unimanual and bimanual performance
This study aimed to better characterize age‐related differences in dexterity by using an integrative approach where movement times and kinematics were measured for both hands. Forty‐five young (age 19–31) and 55 healthy older adults (age 60–88) were evaluated during unimanual and bimanual performance of the Purdue Pegboard Test. Gender effects were also assessed. From video‐recorded data, movement ...
Mate Choice could be Random in Female Rats (Rattus norvegicus)
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2017-11-01)
Female mate choice is often investigated in terms of reproductive success in order to understand how male characteristics contribute to sexual attractiveness. Previous studies have found that females rats prefer mating with their first encounter rather than males visited subsequently, suggesting that the rewarding value of this first encounter is enough to reinforce mating with the first partner. ...
