Learning, memory, and behavior arise from the complex integration of neuronal networks, with the gut–brain axis playing a key role through microbiota, immune signaling, and neural pathways. Gut microflora can influence emotions, cognition, and behavior via metabolites, modulation of inflammation, and communication with the nervous system. Nutrition acts as a central regulator of microbiota composition and function, thereby affecting neural homeostasis and cognitive health.

BIOSPAIN, the largest biotechnology event organized by the national bioindustry association in Europe, was held from October 7 to 9 in Barcelona.
