This term refers to a condition called brain laterality, meaning one side of the brain’s cortex is over stimulated in regards to the other side. The most common form of brain hemisphericity is right brain dominance. The left and right brain are associated with two major hormones in the body, testosterone and estrogen respectively. The female sex is more susceptible to being effected by emotion or fear is because estrogen and the right brain are associated with emotional control. When the brain is constantly stimulated by emotion, it activates the right cortex, causing an overstimulation and leads to right brain dominance.
Other causes of brain laterality are lack of activation of the cerebellum. Cerebellum is the part of the brain that is responsible for our motion detection and balance. If there are fixated joint segments on the left side of the body, the cerebellum will not receive any motion information, leading to a decrease in cerebellar function. The trick is, that all sensory information that comes from the body, goes to the opposite side of the brain. So any lack of motion in a joint segment on the left side of the body, will shut down activation on the right cerebellum. This can lead to activation of the right cortex, leading to right brain dominance.
Muscle control is also stimulated by the opposite side of the brain, so your left arm is controlled by the right cortex. This is important because when a person falls into right brain dominance, the muscles on the left side of the body are over activated. This doesn’t affect every muscle in the body, mainly just the postural muscles that are fired automatically, meaning they fire without any of our control. The majority of postural muscles are the ones that support the spine. When the body becomes right brain dominant, there is an over activation of the left side spinal muscles in regards to the right side, leading to idiopathic spinal scoliosis. This is why the spinal curvature is always to the left.
Prolonged durations of right brain dominance, brain hemisphericity, brain laterality, can lead to many more common symptoms. As the right brain becomes over stimulated, it starts to build more neuronal ties to the brain’s limbic system. The limbic system is what controls our response to a stimulus, and controls our sympathetic nervous system. The sympathetic nervous system is responsible for our Flight or Fight response to a stimulus. When we over activate the sympathetic nervous system, we shut down the parasympathetic nervous system.
Common signs and symptoms of right brain dominance is someone who uses feelings as a way of describing things, someone who has a big imagination, someone that draws and is more interested in art than math.
This can be treated, and alleviated with controlled care. Stimulation of the nervous system on the left side of the body will increase cerebellar function on the right side of the body, inhibiting the right cortex from being over stimulated. Also, lifestyle changes, that allow us to cope with stress with also decrease the emotional stimulation of the right cortex. This therapy takes time, but is very effective.
If you know anyone who demonstrates any of these symptoms, seek a natural treatment plan.
