For a long time, many people believed that human beings only use 10% of their brain capacity. However, research has concluded that this notion is a myth. With that said, you actually are able to unlock your brain’s full potential.
The path to gaining a superbrain starts by understanding the brain and how the cerebral hemispheres function. In this article, we will explore what a cerebral hemisphere is, where it is located, and what are specific functions of each part of the hemispheres.
What Is a Cerebral Hemisphere?
The brain is the epicenter of the nervous system which is found inside the skull.
The biggest part of the brain is located on the top of the head called the Cerebrum. The cerebrum is divided into two parts which are called cerebral hemispheres.
What is a hemisphere definition? A hemisphere is a half of a sphere. Everyone’s brain has two of them where each hemisphere is controlling the opposite side of the body. The right hemisphere of the cerebrum controls the functions on the left side of the body and the left hemisphere controls the right side. Cerebral hemispheres are crucial for our wellbeing as they support cognitive functions and store memories.
Where Are the Cerebral Hemispheres Located?
As mentioned before, two cerebral hemispheres make up the cerebrum which is located on top of the head. This is the biggest part of the brain, taking up to 2/3 of the whole brain.
Cerebra hemispheres undergone the greatest changes throughout human evolution. Today cerebral hemispheres are located on the left and right side of the brain stem, completely covering its front part.
What Are the Specific Functions of Each Cerebral Hemisphere?
Each of the two halves of your brain has its functions in what experts refer to as lateralization. The right cerebral hemisphere helps with vision independence, sense of touch, and object recognition. The left cerebral hemisphere assists in language, logical reasoning, and comprehension.
The hemispheres communicate through the wide flat bundle of neural fibers called corpus callosum.
At the first sight it’s pretty obvious that each cerebral hemisphere hemispheres has its dominant functions.
Left hemispheres being responsible for speech, logical reasoning and language processing and comprehension. And right – responsible for spacial tasks – identifying objects and spaces with any other senses apart from vision.
That’s probably why so many people believe they are left or right brained. Even though each of the hemispheres has some dominant functions, both of them are directly involved in most of the bodily processes.
What Are the Major Regions of The Cerebral Hemispheres?
Each of the hemispheres has four lobes: frontal, parietal, temporal, and occipital. Here are the functions of the different lobes:
1. Frontal lobe
This region of the brain controls:
- Judgment, problem-solving, and planning
- Behavior, personality, and emotions
- Body movements
- Speech, writing, and speaking
- Concentration, self-awareness, and intelligence
2. Occipital lobe
It has one sole purpose, interpreting vision and helps you identify color, movement, and light.
3. Parietal lobe
This region of the cerebral hemisphere is responsible for:
- Interpreting language and words
- Spatial and visual perception
- The sense of touch, temperature, and pain
- Interpreting signals from visual, motor, hearing, memory, and sensory
4. Temporal lobe
This part of the cerebral hemisphere is responsible for:
- Understanding language
- Sequencing and organization
All these parts work together to help you with your daily tasks.
The brain has the ability to adapt by a process called neuroplasticity. In case of a damage, one of the hemispheres has an ability to take on extra functions, which is common in young brains.
Thus, like any other muscle, you can train your brain to become better.
It’s not about mental intelligence, it’s about mental fitness.
