mind power
What power does the brain / mind have on cells?
Does the brain (or mind, whatever you want to call it) has power over cells our body? Can you change the way we do and replace each other, or change the way we look?
The term "mind" is soft. I do not believe there is agreement on the definition used by biologists and neuroscientists. The brain is a complex organ that can regulate many other systems organ, either by the chains of neurons that enervate different tissues (cause muscles to contract). Electrical impulses are sent by neurons that signal chemical release at synapses to communicate with another neuron or muscle. Other ways the brain communicates with other cells is through the release of hormones in the bloodstream. Hormones may change the activity of the digestive system (never start salivating in anticipation of food? Just the idea of eating is enough to release more saliva and start pumping protons from the stomach and digestive enzymes. In an unconscious way, the brain can change how cells grow. During puberty, many hormones return signals to initiate cell division and differentiation in the sexual organs mature. hormonal signals the brain play a role in the regulation of menstruation involves the growth of uterine lining and egg maturation in the ovary. signals of the hormone in anticipation of sex, can make facial hair grow faster. However, you may not want anything to grow. Most of these signals are not under conscious control.
