What Are The Cerebral Hemispheres? And Why Are They Important?

by Mindvalley December 3, 2018

It’s a long-standing myth that humans use only 10% of their brain. The fact is research shows that you’re able to unlock your brain’s full potential by understanding how the cerebral hemispheres of the brain work. The two hemispheres communicate with each other to control muscle function, speech, thought, emotions, reading, writing, and learning.

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

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
  • Hearing
  • Memory
  • 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.

Do you have trouble remembering names?

Maybe you struggle to remember important dates or even basic facts and figures you need for a presentation?

If you do, don’t worry - it’s a common problem.

But what’s also common is the myth that some people are just born with good or photographic memory, while the rest of us just have to struggle.

The truth is, memory is just like a muscle - you can train it to be stronger.

Whether you’re a working professional looking to learn new skills, a student cramming for exams, or even just a senior who’s looking to stay sharp - there are techniques you can do to actively and permanently improve your memory.
