Pictures of preterm infants elicit increased affective responses and reduced reward-motivation or perspective taking in the maternal brain

Preterm-birth increases the risk of several physical, cognitive, neuromotor, and psychosocial problems in children, and is also related to difficulties in the parent-child relationship. Research suggests that the development of early parent-child interactions in general is affected by deviations from typical infant facial characteristics, which may also be important in the case of small, preterm born infants. Therefore, we examined mothers' (N = 22, of whom 17 had no direct experience with preterm birth) neural responses to pictures of preterm and fullterm infants using functional magnetic resonance imaging (fMRI). We also explored whether neural responses to preterm and full-term infants correlated with mothers' self-reported tendencies to be nurturing and protective with children, and with mothers' ratings of affection or aversion toward pictures of preterm infants. Results revealed that, compared to pictures of full-term infants, those of preterm infants elicited more activity in specific areas of the brain (dmPFC, right insula, left caudate, hippocampi, parahippocampi, and PAG), that have previously been associated with processing of negative emotions and with empathy. In addition, less activity was seen in one area of the brain (vmPFC) known to be associated with reward-motivation or mental state understanding and perspective-taking. Higher self-reported maternal nurturance was associated with increased activity to pictures of preterm infants vs full-term infants in the caudate, which might reflect approach- or reward-related processing. To conclude, neural responses to preterm infants are related to reward-motivation, mentalizing, negative emotions, and empathy. Future studies should examine whether such neural processing of preterm infant stimuli might underlie difficulties in the parent-child relationship of parents with a preterm child

What a cute baby! Preliminary evidence from a fMRI study for the association between mothers ? neural responses to infant faces and activation of the parental care system

Infant facial characteristics, i.e., baby schema, are thought to automatically elicit parenting behavior and affective orientation toward infants. Only a few studies, conducted in non-parents, have directly examined the neural underpinnings of this baby schema effect by manipulating distinctiveness of baby schema in infant faces. This study aims to further our understanding of the intuitive nature of parenting, by studying the baby schema effect in mothers of young children (at least one child aged between 2 and 6 years old). Functional magnetic resonance imaging (fMRI) was used to examine mothers’ (N = 23) neural responses to unfamiliar infant faces varying in distinctiveness of baby schema. Also, it was studied how this neural activation to infant faces was associated with maternal nurturance. Results revealed that infant faces elicited widespread activation in bilateral visual cortices, the hippocampus, sensory-motor areas, parietal and frontal cortices, and the insula, which was not modulated by the distinctiveness of baby schema in the infant faces. Furthermore, higher self-reported maternal nurturance was related to increased neural responses to infant faces in the putamen and amygdala, brain regions known to be associated with reward and salience processing. These findings could suggest that in our small sample of mothers some of the core networks involved in reward and salience processing might be less sensitive to variation in distinctiveness of baby schema. Also, unfamiliar infant faces seem to be rewarding only for mothers who report high nurturance. These findings should be considered preliminary, because they need to be replicated in studies with larger samples

Reflecting on Female Beauty: Cosmetic Surgery and (Dis)Empowerment

This project aims to unwrap some of the complexities related to female beauty and the body. It reflects on the second wave radical feminist view that beautifying the female body serves to attract male approval via the male gaze, both of which are deeply entrenched in patriarchal power. This perspective positions cosmetic surgery as a disempowering act for women. In riposte, we turn to third wave liberal feminist ideas to engage with the narratives of ten participants who tell of their personal experiences of, and motivations for, undergoing a cosmetic intervention. We undertake an in-depth exploration of these lifeworld experiences and the interplay of subjectivity and intersubjectivity in the women’s encounters. Findings suggest that a cosmetic intervention is often obtained for the self as opposed to satisfying the “other.” Importantly, cosmetic interventions allow a process to occur in which an individual’s physical body becomes better aligned to her sense of self. From this liberal feminist perspective, cosmetic surgery is positioned as an empowering act.Dziekan Wydziału Ekonomiczno-Socjologicznego (B18112CZAS1175.01; MPK: 2122524000)

Beauty and the Cosmetic Secret

Cosmetic surgery is often linked to the perception that women who resort to cosmetic interventions to alter their physical appearance are vain, superficial, and narcissistic. Few investigations have acknowledged and explored the individual’s personal motivations and experiences of her action and choice with regards to aesthetic surgery. By focusing on subjective experience, alternative insights can be gained on the cosmetic procedure(s) and on how their reshaped body influences an individual’s lifeworld experience. The article explores the perceived benefits and consequences of reshaping, enhancing, and/or reducing a perceived flaw or shortcoming of the body. From this exploration the focus moves to the individual’s subjective and intersubjective perceptions: how she motivates and justifies her physical transformation whilst keeping private, and at times hiding, her surgical intervention. Drawing on narratives from several women, we attempt to understand how they experience cosmetic surgery in terms of their personal sense of self and their everyday social reality.Dziekan Wydziału Ekonomiczno-Socjologicznego (B18112CZAS1175.01; MPK: 2122524000)

Where Cosmic Dawn Breaks First: Mapping the Primordial Overdensity Powering a z 9 Ionized Bubble

Models of cosmic reionization predict that the earliest star-forming systems develop in primordial overdensities which, in turn, create ionized bubbles. With time, these bubbles grow and coalesce until the intergalactic medium is fully ionized. Since Lyman-alpha photons originating in these protoclusters can propagate freely through ionized gas, the highest redshift Lyman Alpha emitters (LAEs) act as valuable tracers of early ionized bubbles. We present evidence that the highest redshift LAE, EGSz8p7 (z=8.68), is likely embedded in such an overdensity. Collectively, in all of HST's deep fields, blank fields and gravitationally-lensed fields spanning >1000 arcmin^2 there are ~30 photometric candidates at z~9, yet a third lie within 3.75' (10 cMpc) of EGSz8p7. To confirm and exploit this extraordinary early overdensity we seek systemic redshifts and diagnostic features only JWST can provide. We propose blind, grism spectroscopy to map the ionized bubble around EGSz8p7 using the [OIII] doublet. A blind survey is optimal for determining a complete census of EGSz8p7's physical neighbors. Spitzer/IRAC color excesses at z>8 imply extreme [OIII] EWs (~6000 A) ensuring efficient use of JWST. Stellar population modeling of the sources around EGSz8p7 may give us the strongest constraints yet on when star-formation first commenced after the Big Bang (i.e., cosmic dawn). Our spectra will likewise constrain the ionizing photon production efficiency, a key unknown in reionization calculations. Our observing strategy is designed for maximum legacy value with a footprint overlapping the CEERS ERS survey and use of the wide F444W grism that will guarantee additional

Brain ultrasonography findings in neonates with exposure to cocaine during pregnancy

Background: Cocaine exposure during pregnancy has been reported to have detrimental effects on the fetus. Objective: To describe the findings on cranial ultrasonography (CUS) as part of a neonatal screening programme for exposed neonates. Materials and methods: The study was a semiprospective analysis of a 12-year cohort of neonates born to mothers who had used cocaine during their pregnancy and who had follow-up according to a strict clinical protocol. Results: In total, 154 neonates (78 boys, 76 girls) were included, of whom 29 (19%) were born preterm, and 125 (81%) were born full-term. Abnormalities on CUS were seen in 37 neonates (24%; 95% CI 18-31%). The abnormalities were classified as minor in 20 (13%; 95% CI 9-19%) and mildly abnormal in 17 (11%; 95% CI 7-17%). None of the infants showed severe abnormalities. The abnormalities were not associated with the duration or maximum amount of cocaine use during pregnancy. Conclusion: None of the infants had severe abnormalities. Detected abnormalities were not correlated with the duration or maximum amount of cocaine use. Given these findings, we feel that routine cranial ultrasonography in this population is not warranted
