11 Surprising Facts About the Human Brain:
The human brain is a remarkable organ that plays an important role in our daily lives. It is the command center of the nervous system and controls everything we do, from our thoughts and feelings to our bodily functions.
Despite its importance, there are still many fascinating and surprising facts about the human brain that are unknown to most people.
In this article, we will explore 11 surprising facts about the human brain that will astound you with its complexity and capabilities.
#1-Brain weight and size
The human brain may be small in comparison to the rest of our bodies, but it is incredibly powerful. On average, the adult human brain weighs about 3 pounds (1.4 kg) and is about the size of a small watermelon. However, don’t let its size deceive you, as it contains approximately 86 billion nerve cells called neurons that form the complex networks responsible for our cognitive abilities.
#2-Energy Consumption of the Brain
Although the human brain represents only 2% of our body weight, it consumes a significant amount of energy. In fact, the brain uses about 20% of the body’s total oxygen and glucose supply, even when we are at rest. This high energy demand highlights the importance of maintaining a healthy diet to support the continued activity of the brain and its functions.
#3-Processing Speed of the Brain
The human brain is an extraordinary multitasker and can process information at astonishing speeds. It is estimated that the brain can transmit signals between neurons at a speed of 268 mph (432 kph). This remarkable processing speed allows us to react rapidly to our surroundings and make split-second decisions.
#4-Storage Capacity of the Brain
Have you ever wondered how much information can be stored in the human brain? Well, the answer may surprise you. Although the brain’s storage capacity is difficult to measure accurately, some studies suggest it may be as high as 2.5 petabytes, which is roughly equivalent to 3 million hours of TV shows. This vast storage capacity enables us to store a lifetime’s worth of memories and knowledge.
#5- Plasticity of the brain
The human brain is not a static organ, despite what many people think. It has an incredible ability known as neuroplasticity, which allows it to change and adapt throughout our lives. Neuroplasticity enables the brain to reorganize neural connections, form new pathways, and even compensate for damage in certain areas. This adaptability plays an important role in learning, recovering from injuries, and developing new skills.
#6- Electrical activity of the brain
The brain generates electrical signals that facilitate communication between neurons. These electrical impulses can be measured using a technique called an electroencephalogram (EEG). Interestingly, the electrical activity of the brain can be affected by a variety of factors such as our thoughts, feelings, and external stimuli. Scientists continue to study the electrical patterns of the brain to gain insight into different mental states and conditions.
#7 – The brain sleep pattern
Sleep is essential for proper brain function and overall well-being. The brain goes through several stages when you sleep, including REM sleep and non-rapid eye movement (NREM) sleep. These stages play an important role in memory consolidation, learning, and emotional regulation. Lack of adequate sleep can impair cognitive abilities, mood, and even physical health.
#8-cerebral hemisphere specialization
The human brain is divided into two hemispheres, the left and the right, which are connected by a bundle of fibers called the corpus callosum. Each hemisphere specializes in different functions. The left hemisphere is often associated with logical thinking, language, and analytical skills, while the right hemisphere is associated with creativity, intuition, and spatial awareness. However, both hemispheres work together in harmony to support our complex cognitive abilities.

#9-Chemical messengers of the brain
Neurons communicate with each other through special chemicals called neurotransmitters. These chemical messengers play an important role in regulating various processes in the brain, including mood, emotions, and behavior. Imbalances in neurotransmitter levels may contribute to mental health disorders such as depression, anxiety, and schizophrenia. The drugs used to treat these conditions often target specific neurotransmitters to restore balance.
#10-Brain’s Perception of Time
Have you ever wondered why time seems to fly by when you’re having fun, but time flies when you’re bored? Well, it turns out that the brain’s perception of time isn’t always accurate. Studies have shown that our perception of time can be affected by factors such as attention, emotions, and novelty. When we engage in enjoyable activities that capture our attention, time seems to pass more quickly. On the other hand, monotonous tasks can make time feel like it’s slowing down.

The brain and gut are more closely linked than you think. The gut has its own nervous system, known as the enteric nervous system, which communicates with the brain through a network of neurons. This communication pathway is often referred to as the gut-brain axis and plays an important role in regulating our emotions and overall well-being. This explains why our inner feelings and emotions are so intertwined.
Frequently asked questions Facts about the human brain:
1-Q: Can meditation benefit the brain?
Ans-Meditation has been found to have many benefits for the brain. Regular meditation practice can reduce stress, improve attention and focus, promote emotional well-being, and increase resilience to stress. Studies have shown that meditation can lead to structural changes in the brain, including an increase in gray matter density in areas associated with memory and emotional regulation. It is a powerful tool for promoting overall brain health and mental well-being.
2-Q: Can the brain be trained to improve cognitive abilities?
Absolutely! The brain is highly adaptable and can be trained to improve cognitive abilities. Activities such as puzzles, reading, learning a new language and playing a musical instrument can stimulate neural connections and enhance cognitive functions such as memory, attention and problem-solving. It’s never too late to start exercising your brain and reaping the benefits of cognitive training.
3-Q: What role does nutrition play in brain health?
Nutrition plays an important role in brain health. The brain needs a constant supply of nutrients to function optimally. Essential vitamins, minerals, and antioxidants that promote brain health and stave off cognitive decline can be found in a diet high in fruits, vegetables, whole grains, lean meats, and healthy fats. Maintaining a balanced diet and staying hydrated are important for optimal brain health.
