Abstract
The human gut microbiome has emerged as a pivotal modulator of brain function and mental health, acting through intricate bidirectional communication along the gut-brain axis. Mounting evidence suggests that microbial communities influence neurodevelopment, neurotransmission, and behavior via pathways involving the vagus nerve, immune signaling, and microbiota-derived metabolites such as short-chain fatty acids and neurotransmitter precursors. This review critically examines the mechanistic underpinnings of microbiota-brain communication and evaluates current findings linking dysbiosis to psyc
