Main idea: The neurons present in the enteric nervous system interact directly with the neurochemicals produced by the microbiota of the gut, thereby influencing the signaling to the central nervous system.
Psychobiotics are a special class of probiotics that deliver mental health benefits to individuals. They produce or stimulate the production of neurotransmitters, short-chain fatty acids, enteroendocrine hormones, and anti-inflammatory cytokines. Owing to this potential, psychobiotics have a broad spectrum of applications ranging from mood and stress alleviation to being an adjuvant in therapeutic treatment for various neurodevelopment and neurodegenerative disorders. The two-way crosstalk between the brain and gastrointestinal system is influenced by these bacteria.
