A revolutionary research has found that the increased oxygen supply at the beginning of life can give a big boost to brain development through the growth of new neurons. The findings set a new direction on how the environment and brain plasticity are related and might be used in the treatment of neurological disorders.
The Importance of Oxygen in Brain Development
The researchers have always believed that oxygen is vital for brain function, but the degree of involvement in neurogenesis (the development of new neurons) was not clear. In an attempt to verify the effect of oxygen, scientists have carried out experiments on newborn mice by placing them in different oxygen conditions.
According to the published results, mice that lived in an oxygenated environment developed more neurons in the part of the brain called the hippocampus, which is responsible for learning and memory. At the same time, those that were given a lower oxygen concentration decreased neurogenesis.
Meaning for the Health of People
This accomplishment indicates that the oxygen provided during the early stages of development could turn out to be an essential factor for the improvement of cognitive skills. It is well known that premature babies suffer mostly from oxygen deprivation. If this is the case, it is only reasonable that oxygen therapy, which is strictly regulated, should help the brain develop normally.
Besides this, the study facilitates new investigative paths for brain diseases like Alzheimer’s and Parkinson’s. In case scientists succeed in activating the pathways of oxygen leading to cell proliferation, they may even consider using it in the treatment of brain injuries and dementia.
Future Research Directions
Although the experiment was done on mice, the scientists are certain that their results can be applied to humans since the brain development of mammals in general is quite similar. Subsequent investigations will focus on:
- The best oxygen levels that would result in the greatest neurogenesis
- How oxygen and other growth factors in the brain cooperate
- Methods of enabling brain repair in adults by applying new therapies
Besides, this study shows how environmental conditions can affect brain health and places oxygen as a major factor in one’s mental development at an early stage.
