72 Surprising Facts About The Human Brain

We all know the brain is one of the most complex parts of the body. It gives commands to the body so that it can perform its functions well. If you think that the human brain can multitask, then you are wrong. It only switches between different tasks.

Here are 72 surprising facts about the human brain

  30.  The left hemisphere is often considered the logical, analytical side and is responsible for language processing, math, and logic.
  31.  The right hemisphere is considered the creative, intuitive side and is responsible for spatial awareness, music, and art.
  32.  The human brain has the ability to rewire and reorganize itself in response to injury, disease, or learning experiences, known as neuroplasticity.
  33.  The human brain contains specialized structures known as “memory centers” that play a role in forming and storing memories.
  34.  The brain’s cortex, which is the outer layer of the brain, is responsible for higher-level processing, such as perception, thought, and consciousness.
  35.  The brainstem connects the brain to the spinal cord and is responsible for vital functions such as breathing, heart rate, and sleep.
  36.  The hypothalamus is a small but powerful region of the brain that helps regulate important functions such as hunger, thirst, and body temperature.
  37.  Amygdala is a tiny almond-shaped structure in the brain that is involved in processing emotions such as fear and anger.
  38.  The basal ganglia is a subcortical group of nuclei in the brain that is involved in motor control, procedural learning, and certain cognitive functions.
  39.  The hippocampus is a region of our brain that is crucial for learning and memory, particularly the formation of new memories.
  40.  The frontal lobe is responsible for a variety of functions, including decision-making, problem-solving, planning, and movement control.
  41.  The parietal lobe is involved in processing sensory information from the body, such as touch, temperature, and pain.
  42.  The occipital lobe is involved in processing visual information from the eyes.
  43.  The temporal lobe is involved in processing auditory information from the ears, as well as memory and language processing.
  44.  Our brain is protected by the skull and cushioned by cerebrospinal fluid, which helps to absorb shock and protect the brain from injury.
  45.  Brain injuries, such as concussions, can have a significant impact on brain function and can lead to long-term effects such as memory problems and mood changes.
  46.  Environmental toxins like lead and mercury can have a toxic effect on the brain, leading to decreased function and developmental problems.
  47.  The brain consumes a large amount of energy, even though it only makes up 2% of the body’s weight, making it one of the most energy-intensive organs in the body.
  48.  The human brain generates a large amount of electrical activity, which can be measured using EEG (electroencephalography) and used to diagnose various neurological disorders.

  64.  The brain can perform unconscious calculations and make decisions before a person is aware of it.
  65.  The brain has a “second brain” in the gut, also called “the enteric nervous system,” that is capable of processing information and making decisions independently.
  66.  The brain is capable of creating hallucinations, both in a waking and sleeping state.

Note:

The human brain is protected by the skull, and it controls all the functions of the body. Information is received through our five senses by the brain, namely, sight, smell, touch, taste, and hearing. In spite of so many studies and research on the brain, we are still far behind in our knowledge about what can be done by a human brain.
