BRAIN(PART 2)

WATER

According to The Guardian, 75% of our brain is made up of water.

WEIGHT

According to the Express, our brain weighs approximately 1.5 kg and represents 2 to 3% of our body mass. In addition, it consumes about 20% of our oxygen.

STORAGE

Our brain is capable of storing the equivalent of 1,000 terabytes of information, according to the Daily Galaxy.

CONNECTIONS

The Daily Galaxy reports that the human brain has more connections than the number of stars in our galaxy.

CONSCIOUSNESS

Consciousness allows us to experience and react in a seemingly self-directed way. However, neuroscientists still can't explain how sensations are processed and translated into subjective impressions.

MEMORY

Human memory is characterized by the ability of humans to 'encode, store, retain and recall information' through neurobiological devices and social interaction.

INTELIGENCE

Intelligence has been popularly defined as one's ability for logic, abstraction, memorization, understanding, self-knowledge, communication, learning, emotional control, planning, and problem solving, according to Encyclopedia Britannica.

PERCEPTION

The main function of the brain is to convert our senses into experiences. This ability to perceive allows us to organize, identify, and interpret sensory information in a way that helps us build and understand our world, according to Utne Reader.

DÉJÀ VU

It's a psychological reaction where the brain transmits the feeling that we've been in a place or have seen a person before, even though we never did. The phenomenon is actually a fault in the brain where the facts that are happening are stored directly in long or medium term memory when the information should go into short-term memory - hence the feeling that we've experienced the situation before, says The Conversation.

DREAMS

Freud and psychoanalysis claim that dreams have the function of 'releasing' repressed desires and fears that embarrass us but are deeply present in our psyche.

REALITY VS. IMAGINATION

When we look at an object, we request a sequence of neurons and patterns from our brains. If we're imagining an object, the process is the same: the same brain sequence will create a representation of the object. Therefore, the brain does not differentiate between reality and imagination.

MOVEMENT

One of the mysteries of the mind is that we manage to move in a controlled and precise manner, even though our motor nerve impulses are considered slow, random, and unpredictable.

PERSONALITY

A study revealed that the shape of our brains can reveal a lot about our behavior and the risks of developing mental disorders.

HOW MUSIC AFFECTS OUR EMOTIONS

Music affects the nervous system directly through the thalamus, so the center of our emotions and feelings can be stimulated, says HealthLine.

PHOBIAS

Over 400 different types of phobias are recognized. According to a study by the Emory University School of Medicine, phobias can be directly related to genetics, the memory of a negative experience recorded in the DNA and passed on from generation to generation.

EXTRASENSORY PERCEPTION

It is the human capacity to acquire information without using any of the five senses. It's like using a sixth sense, says The Telegraph.

PRECOGNITION

Known as premonition, people who claim to experience it get information about future events without having indications in the present that would allow them to come to such conclusion. Premonition can manifest through dreams, according to the Encyclopedia Britannica.

TELEPATHY

It is usually characterized by the interaction between two minds, including the transmission of thoughts, memories, or images, according to IFL Science.
