Abstract South Africa may be a particularly useful exemplar with which to consider some of the potential promises and pitfalls of cultural neuroscience. This chapter draws on our experience as scientists who have worked in the South African context, who have used both neuroscientific and social science methodologies, and who have wondered how best to integrate these often quite different perspectives. We begin by proposing a heuristic conceptual framework that articulates “classical,” “critical,” and “integrative” approaches to cultural neuroscience, and we then use this to exemplify promises and pitfalls of cultural neuroscience in South Africa and to map out a research agenda for the future.

In general, studies show that PAE results in impaired verbal and visual-spatial episodic memory performance in affected individuals and these impairments are unlikely to be secondary to a global impairment. However, impairments on some memory tests are specific to the encoding stage, whereas retention is relatively spared; suggesting that the episodic memory deficit might be influenced, at least in part, by higher order cognitive processes.

Psychoactive substances are subject to several international and national conventions and laws that have emphasised the importance of the 'war on drugs' and supply reduction. At the same time, it is increasingly clear that evidence-based, balanced policies are needed, which address the important differences between alcohol, tobacco, marijuana and other psychoactive substances or drugs. The Prevention of and Treatment for Substance Abuse Act 70 of 2008 speaks to the National Drug Master Plan, which emphasises a range of strategies for addressing the excessive use of alcohol, tobacco, marijuana and other psychoactive substances.

The 10/90 research gap refers to the fact that only
\n10% of the world’s research resources are spent in lowand
\nmiddle-income countries (LMICs) although 90%
\nof preventable deaths occur in these regions: similar
\ndisparities also exist in mental health research (1).
\nA number of efforts have been made to address the
\nmental health research gap, including establishment
\nof priorities and funding for global mental health

Identification of factors predicting OCD and SPD in TTM provides evidence for the relatedness of these disorders and supports their collective classification as obsessive-compulsive and related disorders (OCRDs) in DSM-5. The findings of this study further underscore the importance of assessing for comorbid OCRDs and family histories of OCRDs in clinical practice.

Maternal nutrition and inflammation have been suggested as mediators in the development of various adverse pregnancy outcomes associated with maternal obesity. We have investigated the relation between pre-pregnancy BMI, B vitamin status, and inflammatory markers in a group of healthy pregnant women. Cobalamin, folate, pyridoxal 5'-phosphate, and riboflavin; and the metabolic markers homocysteine, methylmalonic acid, and 3-hydroxykynurenine/xanthurenic acid ratio (HK/XA); and markers of cellular inflammation, neopterin and kynurenine/tryptophan ratio (KTR) were determined in pregnancy week 18 and related to pre-pregnancy body mass index (BMI), in 2797 women from the Norwegian Mother and Child Cohort Study (MoBa). Pre-pregnancy BMI was inversely related to folate, cobalamin, pyridoxal 5'-phosphate (PLP), and riboflavin (<i>p</i> < 0.001), and associated with increased neopterin and KTR levels (<i>p</i> < 0.001). Inflammation seemed to be an independent predictor of low vitamin B6 status, as verified by low PLP and high HK/XA ratio. A high pre-pregnancy BMI is a risk factor for low B vitamin status and increased cellular inflammation. As an optimal micronutrient status is vital for normal fetal development, the observed lower B vitamin levels may contribute to adverse pregnancy outcomes associated with maternal obesity and B vitamin status should be assessed in women with high BMI before they get pregnant.

Urbach-Wiethe disease (UWD) is an extremely rare autosomal recessive disorder characterized by mutations in the extracellular matrix protein 1 gene on chromosome 1. Typical clinical manifestations include voice hoarseness in early infancy and neuropsychiatric, laryngeal, and dermatological pathologies later in life. Neuroimaging studies have revealed a pattern of brain calcification often but not exclusively leading to selective bilateral amygdala damage. A large body of work on amygdala lesions in rodents exists, generally employing a subregion model focused on the basolateral amygdala (BLA) and the central-medial amygdala. However, human work usually considers the amygdala as a unified structure, not only complicating the translation of animal findings to humans but also providing a unique opportunity for further research. To compare data from rodent models with human cases and to complement existing data from Europe and North America, a series of investigations was undertaken on UWD subjects with selective BLA damage in the Namaqualand region, South Africa. This review presents key findings from this work, including fear processing, social-economic behavior, and emotional conflict processing. Our findings are broadly consistent with and support rodent models of selective BLA lesions and show that the BLA is integral to processing sensory stimuli and exhibits inhibitory regulation of responses to unconditioned innate fear stimuli. Furthermore, our findings suggest that the human BLA mediates calculative-instrumental economic behaviors and may compromise working memory via competition for attentional resources between the BLA salience detection system and the dorsolateral prefrontal cortex working memory system.
