Your Microbiome and Your Brain

The video explores the microbiome's significant role in health, particularly its impact on the gut-brain axis. It discusses how microbes in the gut can influence brain chemistry and behavior, challenging previous assumptions about the blood-brain barrier. Research using germ-free mice has shown that gut bacteria can affect stress levels and brain proteins like BDNF. The video also highlights the production of neurotransmitters like serotonin in the gut and the microbiome's influence on the immune system. Although human studies are limited, early research suggests a link between gut microbes and mental health, with future studies aiming to develop new therapies.
