Could your personality be defined by the microbes living in your gut? Science is uncovering a startling connection between the microbiome and complex mental health conditions.
Researchers have discovered that when gut bacteria from patients with schizophrenia are transplanted into germ-free mice, the animals begin to exhibit behaviors and brain chemistry remarkably consistent with the condition. Even more shocking? Independent observers could identify which mice received the bacteria with nearly 100% accuracy, simply by watching how they behaved. It’s a profound look at the gut-brain axis and how the microscopic world inside us might be influencing our thoughts, moods, and actions more than anyone previously imagined.
