“…We think of the brain as a biochemical and electrical organ, so how can a mechanical event, such as a punch to the face, cause unconsciousness? “…”Granted it’s extreme, but it demonstrates how mechanically sensitive the brain is.”…It seems neurons are also hooked together in a mechanical network, like the cogs in a finely tuned clock. The forces that pass between them might be an unknown way for our brains to store memory and adapt quickly to new circumstances -ensuring that they always run like well-oiled machines….our nervous system is buzzing with movement – albeit at the nanometre scale – setting the scene for a mechanical understanding of the brain…the greater the force applied to an axon terminal, the greater the number of neurotransmitter molecules that are available for release across the synapse. In this way,the movements could alter the strength of the signal and consequently the plasticity of the synapse – key changes that might be a means of storing information during learning and memory…Ultrasound therapy:… external mechanical forces can interfere with processes in the brain, potentially answering that mystery of the boxing knockouts. If our synapses and neurons are tuned to fine mechanical forces, then a blow to the head might disrupt their signalling, forcing them to open up ion channels and activate receptors…One reason for excitement is the possibility of using ultrasound to treat brain disorders.”
This interesting article reveals the latest scientific findings on the brain’s plasticity. Read the whole article to find out how scientists have been able to observe the movement in the brain. It seems that the power of musical waves can cause shifts and movements in the brain. What does that mean in terms of future potential therapeutic strategies? How could this affect the treatment of brain disorders? Could hypnotherapy become a complementary technique to a future ultrasound therapy?
