Answer

  1. The human brain weighs about 1.5 kilograms.
  2. The cerebellum controls voluntary muscle movements. The cerebrum is in charge of senses, personality, emotions, learning, and speech. The brainstem regulates vital body systems like the heart, lungs, and circulatory system.
  3. The right side of the brain controls the muscles on the left side of the body and is responsible for face recognition, visual imagery, and creativity. The left side of the brain dominates logical functions and math. It is sometimes called the 'digital brain.'
  4. The brain needs regular workouts, such as studying, solving puzzles involving numbers and letters, and memorizing facts.
  5. Neurons transmit signals between each other to complete various processes, including thoughts, voluntary and involuntary movements, and sensory experiences. If all neurons worked simultaneously, they would produce enough electricity to light a low-wattage light bulb.
