Microbiota and the social brainMany theories have been developed to explain why animals exhibit certain social behaviours, the impact of the #microbiota, however, has rarely been considered.  In a review published in Science Mag this month, scientists have examined several pre-clinical and clinical trials investigating the effect of the microbiota on the social brain. It has been discovered that through a diverse set of pathways the gastrointestinal microbiota is able to send signals to the brain, this is known as the #microbiota-gut-brain axis. The microbiota plays a key role in neurodevelopment from early life into adulthood influencing processes such as #neurotransmission and #neuroinflammation as well as behaviour throughout lifespan. With animals having evolved in a microbial world, these signals may have influenced the animal brain throughout evolution.
