Right brain hemispheres are the reason left handed people are right-handed, and vice versa. Lateral part of brain: a set of smaller evolutionarily older brain structures which surround the brain’s top. The limbic system plays more complex roles in instincts, emotions, and eating behaviors. These areas are responsible for our emotions and behaviors.
A phenomenon which happens when one side of the brain dominates over the other. In rare cases, both hemispheres of the brain develop to a certain extent. When this happens, it’s known as hemispheric dominance. This dominance could happen due to genetic factors or due to handedness. With age the size of brain cells tends to become larger in some areas than in other areas. There is an example where a person with a right handed brain will become left handed with age, and vice versa. However, there are also instances where this is not the case, and the extent of change may depend on handedness or general brain development.
Also known as handedness. There are times when two persons, who are of same sex and have the same handedness can have the same degree of hemispheric dominance. When the dominant hemisphere is the left one, this means that the person tends to be a lefty. When the dominant hemisphere is the right one, it indicates that the person tends to be a righty. People often experience left hemispheric dominance for long periods of time without being aware of it. There are other causes of hemispheric dominance such as left handedness gene hypoplasia, handedness due to cerebral tumors, damage of brain tissue during brain surgery, etc.
Although sex does not affect brain structure, it does impact the pattern of brain changes which take place. For example, men tend to have left brain hemispheres while women have right ones. There are other factors such as handedness which can also have significant impacts on brain asymmetry.
Some colors have been shown to influence brain activity more than others. Grey colors are most effective in increasing the brain’s firing rate while green has been found to be more effective in reducing the brain’s firing rate. Colors can also affect how we think and how we see. For example, blue and green are associated with rational thinking and yellow and orange are associated with emotional thinking.
These differences are based on genetic differences between people. These genetic differences are then translated into structural and functional brain differences. The more similar the structural and functional brain changes between two people, the more likely they are to share similar patterns of brain dysfunction. When a similar structural and functional brain difference is found between two individuals, this is an indication that similar genetic influences also affect brain dysfunction. This can also help researchers find which genes are responsible for brain dysfunction.
There are other factors affecting brain function such as the individual’s age and general health. Brain structures tend to consolidate as people get older. However, as people age, the brain’s plasticity, or flexibility decreases because it becomes more difficult to change the brain’s structure. Research findings that link changes in brain’s plasticity to changes in brain dysfunction show that older individuals who experience less plasticity in their brain tend to suffer from more severe brain impairments.
There have been studies that have shown that people who have a higher number of close relatives may have higher than normal chances of developing brain dysfunction. Researchers believe that identical twins are the most likely to share similar brain structures. People who share identical twins and people who do not share identical twins, however, do not share equal amounts of brain volume. These studies suggest that this could be due to genetics. If your family has a history of brain problems, you have a greater chance of developing them also.
Brain Structure And Function
New research is showing that the brain’s overall structure is related to the overall functions of the brain. Those with better functioning brain structures are able to perform better emotionally, cognitively and emotionally. Those who have less healthy brain structures tend to struggle with emotion and cognition as well as with the ability to process information.
New research is indicating that the sex of an individual’s brain plays a role in the brain’s structure. Men have larger brain volumes than women. Women on the other hand have smaller brain structures. The study also indicated that those who were younger at the time of birth have larger brain volumes than those who were older at the time of birth. It was found that the brains of girls on the age of seven had a larger volume of white matter compared to that of boys. This suggests that the differences observed in brain structures are a result of age and gender.
