Our ability to think, rationalise, and resolve complex issues sets us apart, making us a superior species of our planet. The human brain has unlimited potential and the amount of information and sensations it registers within seconds is unfathomable. Our brain is divided into three parts- the Cerebrum, the Cerebellum, and the Brain Stem. Each part is then further divided into mini sections to achieve a perfectly functioning human body. Come, let’s look at how our brain functions and discover which part of the brain is responsible for our personality and which part controls our breathing. The Cerebrum The largest part of the brain, the Cerebrum is divided into two hemispheres- the left and the right hemispheres. The left hemisphere controls the right side of the body and the right hemisphere controls the left side of the body. Each hemisphere is then further split into four different regions called lobes that control and interpret all the information. The frontal lobe gets activated while we plan and resolve different problems or situations. It controls various human faculties ranging from our body’s movements to our speech. It also determines our levels of concentration, intelligence, and personality traits; making us who we truly are. So, if someone asks you why your mind wanders into distant fields during a lecture or why you are so shy around people, you’ll have a solid, biological answer to back-up your argument. The occipital lobe receives and processes the visual images. It is only because of this that we see the vivid hues of blue in the sky or the green trees with red flowers growing in our yards. The temporal lobe is located near our ears and is responsible for our auditory faculties. It also triggers our emotions and helps us with our pronunciations or when we learn a new language. Along with this, the temporal lobe oversees our memory as well. So the next time you successfully learn a new concept or theorem, don’t forget to thank your temporal lobe. The parietal lobe enables our sense of touch, pain, and temperature. It helps us identify different objects and surfaces with just a touch and lets our body feel all the variations in temperature. It also gives us a spatial and visual sense, making it easy for us to navigate through different rooms and roads. The Cerebellum Located directly under the Cerebrum, the Cerebellum, controls our body’s movement, balance, and posture. It receives information from the sensory receptors, spinal cord, and the different parts of the brain to compile all the information and maintain perfect body posture. Any injury to this part of the brain will cause a loss of basic motor skills and coordination, leading to tremors/shaking in the body. Now imagine, you wouldn’t have been able to play your favourite game or dance to your favourite beats if not for the supportive and thoughtful cerebellum! The Brain Stem Just like a good messenger, the duty of the brain stem is to control the message flow from the brain to the rest of the body. It connects the brain to the spinal cord and controls our swallowing, breathing, and blood pressure. Another significant role of the brain stem is to maintain consciousness and regulate our sleep cycle. So, when your good night’s sleep is disturbed the next time, you know which part of the brain to blame. Now you know how your brain works in its full capacity so that you can think, read, play, sing or in short, do whatever you want to do. You can also get a 360° view of the human brain on the Extramarks Interactive Learning App to see how it actually looks like. The virtual reality modules are designed to enhance your comprehension and engage all the lobes of your mind for better retention. It will activate all your senses and your doubts will stand no chance in front of these interactive learning modules.
