These microbial chemicals can act on the ENS and vagus or reach the brain to modulate neurotransmission, neuroinflammation, and neuronal health, representing a direct molecular link between gut bacteria and brain function
6 Evaluation of neurotransmitter concentrations 6.1 Dopamine assay In the presence of hydrochloric acid, dopamine oxidizes to form an indole derivative that binds to trihydroxyindoles and forms a fluorescent complex, whose absorbance at 485 nm is proportional to the concentration of dopamine (44)
