Myelination is an essential part of human brain development. Nerves can only conduct pulses of energy efficiently if covered by myelin. Like insulation on an electric wire, the fatty coating of myelin keeps the pulses confined and maintains the integrity of the electrical signal so that it has a high signal-to-noise ratio. When the insulation on a wire is damaged or
The prefrontal portions of the cerebrum have a profound influence on human behavior.2 If an individual is injected with vaccines,most of which have adjuvants like mercury and aluminum compounds, as well as foreign proteins (some from other species in which the vaccines were grown) and biological organisms, unprotected nerves may be impacted. The argument for a role of vaccines in the development of autistic disorders hinges on these biological effects upon nerves, damaging them in a way that influences behavior and learning patterns.
The argument for adjuvants evoking an auto-immune response does not hinge on any inherent neuro-toxicity of these compounds, but on the initiation of an allergic response.
