Paul is a researcher who has studied the endocannabinoid system (ECS). According to a review published in PubMed[1], the ECS is a widespread neuromodulatory network involved in the developing central nervous system as well as playing a major role in tuning many cognitive and physiological processes. Harvard Health Publishing[2] has also discussed the importance of the ECS, noting that it is essential and mysterious. A paper published in PubMed[3] further explains the physiology and pharmacology of the ECS, noting that it is an ubiquitous lipid signalling system that appeared early in evolution and which has important regulatory functions throughout the body in all vertebrates.
TEDx Talks[4] has also discussed the ECS, noting that it is a revolutionary system. Finally, Medical News Today[5] has discussed the ECS, noting that it is a biological system in the body that helps regulate and balance key bodily functions.
