Research has shown there can be sex differences between how male and female brains are wired. An ASU study found that the cerebellum, which was thought to mainly control motor skills, plays a role in learning during adolescence — but that role differs in males and females. Studying sex differences in brain development can help us better understand and treat neurodevelopmental disorders, which can have different symptoms in males and females.

ASU researchers found a link between a chronic viral infection in the gut and the development of Alzheimer’s disease. In some people, a common virus may remain active in the gut and travel to the brain via the vagus nerve. Once there, the virus can contribute to changes tied to Alzheimer’s disease. If the hypotheses are confirmed, scientists may be able to test whether existing antiviral drugs can treat or prevent this form of Alzheimer’s.

ASU research shows contact with a common weed killer can cause lasting damage to the brain. Exposure to the active ingredient glyphosate can inflame the brain and increase risk of neurodegenerative disease. Glyphosate is the most common chemical herbicide used in the global market and often used in agriculture. The EPA considers certain levels of glyphosate safe, but recent studies like this one raise questions about current safety thresholds.
