Ingestion of Lactobacillus strain regulates emotional behavior and central GABA receptor expression

Ingestion of Lactobacillus strain regulates emotional behavior and central GABA receptor expression in a mouse via the vagus nerve SUMMARY: This study looked at the effects of Lactobacillus rhamnosus on GABA receptors and the role of the vagus nerve in the gut-brain connection. Results showed that L. rhamnosus decreased cortisone levels in stressed out mice… Continue reading Ingestion of Lactobacillus strain regulates emotional behavior and central GABA receptor expression

Prebiotic Intervention for Children with Autism

A prebiotic intervention study in children with autism spectrum disorders (ASDs) SUMMARY: This study tested the effects of diet and prebiotic on children with autism. The exclusion diet was a gluten-free, casein-free diet and the prebiotic was a galactooligosaccharide that selects for beneficial bacteria in the gut. The study found that the combination of the… Continue reading Prebiotic Intervention for Children with Autism

How the Microbiome Can Change Brain Development

Early Disruption of the Microbiome Leading to Decreased Antioxidant Capacity and Epigenetic Changes: Implications for the Rise in Autism SUMMARY: This is a rather long, but very interesting, article about all the ways gut microbiome can be disrupted. The products of the the gut microbiome can affect brain development, but the article also focuses on… Continue reading How the Microbiome Can Change Brain Development

How the Microbiome Might Affect Microglia

Emerging Developments in Microbiome and Microglia Research: Implications for Neurodevelopmental Disorders SUMMARY: Short chain fatty acids (SCFAs) produced by gut bacteria influence the way microglia develop. This then affects the way synapses are pruned, myelination, and other aspects of brain development. There are three types of SCFAs: acetate, butyrate, and propionate. They each have different… Continue reading How the Microbiome Might Affect Microglia
