Prenatal Exposure to Air Pollution and Early Life Stress Effects on Hippocampal Sub regional Volumes and Associations with Visual-Spatial Reasoning may lead to severe complications like brain-derived neurotrophic factor.
<h3>
What are the Effects on Hippocampal Sub regional Volumes?</h3>
- The hippocampus is also changed by exposure to air pollution, with various effects seen in different hippocampal subfields.
- Following perinatal air pollution exposure in animal models, decreased structural integrity throughout the hippocampus, decreased neurogenesis in the dentate gyrus, and activated microglia in the dentate gyrus and CA1 subfields have all been noted.
- It has been demonstrated that prenatal exposure to PM2.5 is followed by decreased hippocampus brain-derived neurotrophic factor (BDNF) expression and decreased dendritic branching in the CA1 and CA3 subregions.
- In the past, studies on humans have also concentrated on polycyclic aromatic hydrocarbons (PAHs), a class of air pollutants produced by incomplete combustion of organic materials and cigarette smoke, grilling, oil- and coal-burning power plants, and vehicle emissions.

Contractionary money policy is used to combat inflation. In short, contractionary fiscal policy hamper economic growth by increasing interest rates.
Contractionary policy increases the cost of borrowing. It can decreases GDP and dampens inflation, but also leads to reduced disposable income. Another negative side effect is it makes an increase in the unemployment rate. Disposable income itself is the amount of money that households have, available for spending and saving after income taxes accounted.
