Because of the timetable of fetal development and the changes in maternal and placental physiology medicine woman cast 250 mg flutamide with amex, the consequences of stress exposures will vary based on the gestational period of exposure. Although findings regarding the nature of prenatal influence on postnatal functioning are well established in animal models, it is critical to acknowledge that the differences in reproductive and stress physiology, even in very closely related species such as humans and nonhuman primates, limit the validity of generalizing from animal models (Smith and Nicholson, 2007). For these reasons, this chapter primarily focuses on studies of gestational stress in humans. Cortisol is thought to play critical roles in the promotion of fetal maturation in preparation for extrauterine life. Morphologically, the fetal adrenal gland comprises two zones: the outer, definitive zone, and the large, inner fetal zone. The fetal and definitive zones can be recognized after the eighth gestational week. The fetal adrenals grow rapidly until the third trimester so that at term the fetal adrenals are significantly larger, relative to body weight, than the adult adrenals. The human fetal adrenal has steroidogenic enzymes as early as the seventh gestational week, and cortisol secretion can be detected as early as eighth week. There is evidence that the fetus responds to pain with an increase in cortisol during the latter half of gestation (Gitau et al. Neurodevelopmental processes including neurogenesis, migration, neuronal differentiation, dendritic arborization, axonal elongation, synapse formation and collateralization, and myelination proceed at an exceptionally rapid pace throughout the fetal period (Bourgeois, 1997; Sidman and Rakic, 1973). We specifically discuss regions of the brain that are both integral to the regulation of stress responses and vulnerable to exposure to stress hormones, including the hippocampus and amygdala. Both are identifiable between 6 and 8 gestational weeks, and by term, the basic neuroanatomical architecture of these regions is present. Limited information exists regarding the time course of prenatal development of cortisol receptors in humans. There is evidence that both types of cortisol receptors are present in the human hippocampus by 24 gestational weeks (Noorlander et al. Exposure to prenatal maternal biological and psychosocial stress influences the developing fetal brain and endocrine systems producing long-term effects on cognition, emotion, and physiology in the offspring (Kapoor et al. Evidence for persistent organizational changes or programming influences on the nervous system has been growing and may include changes in neurotransmitter levels, cell growth and survival, and adult neurogenesis. In a human study of over 400 pregnant women, maternal gestational cortisol secretion was found to be inversely related to ultrasound measures of fetal brain size in early, middle, and late pregnancy (Li et al. These data from human and animal models suggest endocrine and brain mechanisms by which early-life stress may provoke long-term effects on stress, emotional regulation, and cognition (see Joëls and Baram, 2009; Seckl, 2007 for reviews). However, studies that have controlled for these key sociodemographic factors as well as obstetric risk factors continue to find a correlation between maternal stress and preterm birth, suggesting that psychological functioning over and above contextual stress affects birth outcomes. Preterm birth is associated with pervasive developmental delays (Aarnoudse-Moens et al.

Visually derived semantic codes contain the information relative to judgments that can be based on the physical structure alone and are independent of identity treatment kennel cough flutamide 250 mg purchase with visa, emotional expression, and facial speech, such as gender, race, age, and some social attributions. Identity-derived semantic codes contain all the information one has acquired about a specific person that one knows. Independent processing of identity and expression after successful structural encoding is a main prediction of the Bruce and Young model (1986). However, the ideas of view-invariant and structural encoding, of a relative functional divide between view-invariant and expression processing, are supported by much empirical evidence. Recent computational models have further established how view-invariant face identity recognition may be achieved mathematically through face-specific internal models of viewpoint transformations (Anselmi et al. These models provide an important theoretical link between the empirical observations of view invariance and domain specificity in human face identity recognition and give computational flesh to the idea of structural encoding. Another class of face-processing models is represented by the prototype-based or face space model (Valentine, 1991, 1999). This type of model has been formulated with the goal of providing a unitary account of various phenomena of face processing including recognition and identification of race and gender. The basic assumption that these models make is that any face can be represented within a multidimensional space. The number of variables needed to discriminate between faces determines the dimensions of the space. The center of the space is assumed to represent the average value of a population on that specific dimension. What makes a face more or less recognizable among other faces is the distance between the target face and neighboring faces in the space. The creation of average faces gives rise to prototypes, which are presumably stored in memory. The concept of "face space" is quite agnostic to what the dimensions of such space specifically represent. In line with other existing empirical data in both species, at least some of the earlier studies in rhesus macaques have tended to emphasize the role of particular facial features in isolation or combination (Freiwald, Tsao and Livingstone, 2009), whereas studies in humans have additionally emphasized the role of second-order relations (Burton et al. The dissociation between shape or position information and facial appearance information additionally confers some degree of view invariance to the model and is empirically reflected in the observed differential selectivities of face patches (Chang and Tsao, 2017). From a developmental perspective, these important results raise the question of how such an internal model of face shape and features may emerge in infancy and childhood, presumably facilitated by an ability to detect facelike patterns from birth (Tsao and Livingstone, 2008). Both implementations make very similar predictions, although overall norm-based coding appears to better account for empirical data than exemplar-based coding (Chang and Tsao, 2017; Leopold et al. Norm-based coding may also, under some assumptions, provide an efficient solution to the view-invariant problem where view invariance would only need to be learned with respect to the prototype (or norm), whereas other faces would be coded with respect to such invariant norm. This means that there is no need to learn how all faces look from all possible angles, etc. Thus, face space models can be reconciled with the original Bruce & Young model (1986) because they provide a potential mechanism for structural encodingdthat is, the multidimensional representation of faces with respect to a norm or prototype may form the basis of invariant face identity recognition.
