Cerebrospinal fluid is a clear liquid that flows in and around the brain and spinal cord. It is produced by tissues in the brain’s ventricles and serves several important biological functions, including providing nourishment to the brain and protecting the brain and spinal cord from injury.

Dispenza outlines a specific breathing exercise in Becoming Supernatural that he claims forces the cerebrospinal fluid upward along the spinal cord to the brain, carrying electromagnetic energy stored elsewhere in the body. This causes the brain to produce gamma brain-wave patterns.

Epigenetics is an emerging field of scientific study that explores how external factors affect the expression of genes. Dispenza discusses the role that emotions play in gene expression and how the chemical changes produced by emotions can either up-regulate (produce an increased expression) or down-regulate (produce a decreased expression) certain genes.

Heart coherence is a state of alignment between the heart’s rhythm and other bodily systems. Becoming Supernatural presents studies conducted by the HeartMath Institute, which support the idea that achieving heart coherence through practices such as breathing and meditation has significant benefits for physical, mental, and emotional health and wellbeing. Sustaining heart coherence creates a measurable magnetic field that projects beyond the body; this frequency carries information that can influence the heart of another person.
