Microbiota–Gut–Brain Axis

Recent studies on the gut–brain axis suggested that the gut contains millions of nerve cells, eventually forming an extensive network called the enteric nervous system (ENS). This enteric nervous system is also considered our second brain (Gershon, 1999). The ENS and the central nervous system (CNS) are mainly connected via the vagus nerve and form the gut–brain axis (Goyal and Hirano, 1996; Flannery et al., 2019). The communications within the gut–brain axis occur through the autonomic nervous system, enteric nervous system, neurotransmitters, hormones, and immune responses (Figure 1) (Cryan and Dinan, 2012). Neurotransmitters produced in the gut influence our emotions by regulating the gut–brain axis. Around 90% of neurotransmitters, such as serotonin, are produced in the gut (Mohammad-Zadeh et al., 2008; Warner, 2018). The human gut microbiome consists of trillions of bacterial cells, which is 10-fold more significant than human body cells (Chauhan, 2017; Kumar et al., 2018).
