“…Specifically, it is known to cause hypophagia or hyperphagia in rats and humans. 7,8,34 Following a week of chow-only feeding interrupted midweek by 1 day of PF þ chow, half of the BEPs and half of the BERs (N ¼ 10/group) were subjected to four 3-sec bouts of 0.6 m-scrambled footshock at lights out (see Hagan et al, 7 for procedural and apparatus details). The other weightmatched rats of each group were placed in the shock alley for the same amount of time but no current was delivered.…”

“…Intermittent intake of PF alone promotes subsequent binge-like eating; 1,2 it also interacts with caloric restriction 3 and stress 4,5 to produce binge-eating; [6][7][8] and it changes central reward substrates 9,10 in ways similar to that caused by drugs of abuse. 2,11,12 It is also well known that palatable junk food contributes to passive overeating, weight gain and obesity in humans.…”

“…7,10 Others have used a similar sweet/fat combination in their choice of PF (Reese's peanut butter chips) with the same animal model. 8 The combination of sucrose and fat is a very common composition of many junk foods and their consumption is associated with increasing body mass index, particularly in women. 16,33 We first tested the consistency of a high vs low intake of PF pattern within rats (i.e., are high or low PF eaters always high or low PF eaters?…”

Objective: To determine the stability of individual differences in non-nutritive 'junk' palatable food (PF) intake in rats; assess the relationship of these differences to binge-eating characteristics and susceptibility to obesity; and evaluate the practicality of using these differences to model binge-eating and obesity. Design: Binge-eating prone (BEP) and resistant (BER) groups were identified. Differential responses to stress, hunger, macronutrient-varied PFs, a diet-induced obesity (DIO) regimen and daily vs intermittent access to a PF þ chow diet, were assessed. Subjects: One hundred and twenty female Sprague-Dawley rats. Measurements: Reliability of intake patterns within rats; food intake and body weight after various challenges over acute (1, 2, 4 h), 24-h and 2-week periods. Results: Although BEP and BER rats did not differ in amount of chow consumed, BEPs consumed 450% more intermittent PF than BERs (Po0.001) and consistently so (a ¼ 0.86). BEPs suppressed chow but not PF intake when stressed, and ate as much when sated as when hungry. Conversely, BERs were more affected by stress and ate less PF, not chow, when stressed and were normally hyperphagic to energy deficit. BEP overeating generalized to other PFs varying in sucrose, fat and nutrition content. Half the rats in each group proved to be obesity prone after a no-choice high fat diet (DIO diet) but a continuous diet of PF þ chow normalized the BEPs high drive for PF. Conclusion: Greater intermittent intake of PF predicts binge-eating independent of susceptibility to weight gain. Daily fat consumption in a nutritious source (DIO-diet; analogous to a fatty meal) promoted overeating and weight gain but limiting fat to daily non-nutritive food (PF þ chow; analogous to a snack with a low fat meal), did not. The data offer an animal model of lean and obese binge-eating, and obesity with and without binge-eating that can be used to identify the unique physiology of these groups and henceforth suggest more specifically targeted treatments for binge-eating and obesity.

“…It has a direct impact on genetically inherited risk factors and resilience. [11][12][13][14][15][16][17][18][19][20][21][22][23] With the aim of measuring the contribution of parental behavior to the development of appropriate bonds between parents and children, the Parental Bonding Instrument (PBI) was created in 1979 through successive factor analyses, based on 114 items taken from the literature deemed as major parental qualities for normal development. 24 PBI is a self-administered Likert scale (0 to 3) instrument, with 25 questions related to father and mother, in which subjects answer how similar those behaviors were to their parents' behavior until the age of 16 years.…”

OBJETIVO: O artigo apresenta a adaptação transcultural do Parental Bonding Instrument, um questionário auto-aplicável desenvolvido em 1979 e usado desde então para avaliar a percepção da qualidade do vínculo com os pais até os 16 anos. MÉTODO: Foram realizadas as etapas de equivalência conceitual, equivalência dos itens, equivalência semântica, equivalência operacional, equivalência funcional e aprovação da versão final pelo autor original do instrumento. RESULTADOS: Os critérios de equivalência foram satisfeitos, tendo a versão final sido aprovada pelo autor do instrumento original. CONCLUSÃO: A adaptação do Parental Bonding Instrument disponibiliza para uso um instrumento que já demonstrou ser extremamente útil em pesquisas de risco e resiliência nas últimas décadas, ao avaliar a percepção de características do comportamento dos pais tradicionalmente associadas ao desenvolvimento da personalidade.

“…Increased early maternal care by high licking/grooming dams is associated with decreases in fearfulness and anxiety-like behavior in offspring across several measures, both social (Menard and Hakvoort, 2007) and non-social (Caldji et al, 1998;Francis et al, 2000;Hancock et al, 2005;Menard et al, 2004;Menard and Hakvoort, 2007;Starr-Phillips and Beery, 2014). In reaction to a stressor, offspring of low licking/grooming dams mount what is potentially a less adaptive response, including increased adrenocorticotropic hormone (ACTH) and plasma corticosterone (CORT) as well as impaired glucocorticoid (GC) sensitivity, resulting in a delayed GC feedback on the hypothalamic-pituitaryadrenal axis and, therefore, an extended rise in CORT (Liu et al, 1997).…”

Intergenerational transmission of sociality: the role of parents in shaping social behavior in monogamous and non-monogamous species

Social bonds are necessary for many mammals to survive and reproduce successfully. These bonds (i.e. pair-bonds, friendships, filial bonds) are characterized by different periods of development, longevity and strength. Socially monogamous species display certain behaviors not seen in many other mammals, such as adult pairbonding and male parenting. In our studies of prairie voles (Microtus ochrogaster) and titi monkeys (Callicebus cupreus), we have examined the neurohormonal basis of these bonds. Here, we discuss the evidence from voles that aspects of adolescent and adult social behavior are shaped by early experience, including changes to sensory systems and connections, neuropeptide systems such as oxytocin and vasopressin, and alterations in stress responses. We will compare this with what is known about these processes during development and adulthood in other mammalian species, both monogamous and non-monogamous, and how our current knowledge in voles can be used to understand the development of and variation in social bonds. Humans are endlessly fascinated by the variety of social relationships and family types displayed by animal species, including our own. Social relationships can be characterized by directionality (either uni-or bi-directional), longevity, developmental epoch (infant, juvenile or adult) and strength. Research on the neurobiology of social bonds in animals has focused primarily on 'socially monogamous' species, because of their long-term, strong adult affiliative bonds. In this Review, we attempt to understand how the ability and propensity to form these bonds (or lack thereof), as well as the display of social behaviors more generally, are transmitted both genomically and non-genomically via variation in parenting in monogamous and non-monogamous species.
