By Emily Bell, PhD Dr. Emily Bell is Researcher at the Neuroethics Research Unit, Institut de recherches cliniques de Montréal (IRCM). Dr. Bell’s MSc and PhD research in Psychiatry at the University of Alberta focused on investigating brain activity in mood and anxiety disorders using functional magnetic resonance imaging (fMRI). Her postdoctoral work shifted her into the field of neuroethics, where she examined ethical and social challenges associated with deep brain stimulation in psychiatric disorders. As an investigator of the Neuroethics Core of NeuroDevNet , a Canadian Network of Centres of Excellence , Dr. Bell has been involved in a wide range of network activities and research in the area of pediatric ethics. This includes recent work on the implications of stigma for public health policies and practices in fetal alcohol spectrum disorder and ethical concerns associated with the transition of youth with neurodevelopmental disorders to adult health services. Dr. Bell has bee...

What if how wealthy your parents were before you were born and while you were developing changed who you are, how smart you are and how well you are going to do in life? Well, it turns out that your socioeconomic status during development really does affect your life that dramatically. In a recent review by Meany et al. the authors discuss how different aspects of low socioeconomic status affect childhood development. In the first part of this blog post I will discuss the findings of this article and in the second I will discuss the ethical issues of discussing this type of human condition as a disease. Socioeconomic status' influence on development ( source ) According to Meany et al. socioeconomic status has wide ranging and influential effects on the developmental outcomes of childhood development. These effects may be accounted for by three quantifiable variables: access to quality prenatal care, the quality of parental care, and the quality of stimulation from the home en...

The question of socioeconomic status in scientific research is an interesting one. Many experiments do not take socioeconomic status into account, yet studies show that socioeconomic status can significantly alter the human brain. The article, “Socioeconomic status and the brain: mechanistic insights from human and animal research” addresses some of these issues. However, one of the main problems I noticed with this article is the equivalence of socioeconomic status with quality of parental care. The article seems to associate lower socioeconomic status with parental neglect. Conversely, higher socioeconomic status is associated with higher quality parental care. While there may in fact be a correlation, status is by no means a perfect predictor of parental quality. Parental care in rats ( source ) One of the studies cited in the article uses lack of grooming in rats as a model for low socioeconomic status based on the idea that parental care is equated to status. However, this model s...

As we have witnessed firsthand through the recent presidential election campaign season, this topic is as electrifying as any, placing labels of “haves” and “have-nots”. With the notion held by some that this is due to a lack of effort or motivational drive alone, disdain is often an emotion conjured in the minds of many when discussing poverty; but, what if the differences between an individual of high socioeconomic status and lower status was more than just attitudes, but was actually manifestation of completely different thought process? What if just the idea of being of a lower socioeconomic status was detrimental or toxic to the long-term development of the brain? Socioeconomic status might have neural effects ( source ) Numerous studies have begun to bring to light evidence that perhaps motivation or will may not be the only difference between socioeconomic status (SES), but it may lie even more intrinsically. Some evidence exists that individuals of different socioeconomic st...
