Does our environment affect the genes in our brains?

• There a link between differences in IQ test performance and the activity of certain genes? Researchers have shown that modifications in the structure of a specific gene have a negative impact on individual test performance. 
•  This suggests that environmentally-induced epigenetic changes to our genetic material have a greater impact on intelligence than previously thought.
• Stress and adverse life experiences are examples of environmental factors that can affect gene activity, leading to structural changes in our genetic material (genome).
• The researchers are hoping to conduct more in-depth studies to determine the extent of environmentally-induced neurobiological modifications, as well as the degree to which these modifications affect IQ test performance.
