The autonomic nervous system and cortical systems function similarly in low-risk newborns whether they experienced labor and natural birth or were born via elective cesarean section. However, those who were delivered via C-Section following long periods of labor had increased accelerations in heart rate and lower gamma frequency EEG a day after birth than the other two groups.

Two months after injecting alpha-synuclein into the intestines of rats, researchers discovered the proteins had traveled to the brain via peripheral nerves. Four months later, the pathology was greater. Additionally, the protein had traveled to the heart. The study supports the hypothesis that Parkinson's disease may begin in the intestinal system before migrating to the brain. Read More
Pupillary response in those with PTSD differs from people who have not experienced traumatic events.
