How the Brain Works.

How your brain responds to reading, fear, and sees your surroundings. By Meagan R.

How does reading affect the brain?

     Reading causes changes in your brain. These changes usually linger in the brain for about five days. The change is a height of connectivity in the left temporal cortex. The left temporal cortex is associated with with receptivity of language. Reading is a work out for your brain. Your brain must see the words, register what they mean, and put it all together to make a story. Reading, especially the genre fiction, also makes you use your imagination.

How Does the Brain Respond to Fear?

     First of all, you need to know what fear is in order to know what the brain reacts to it. fear is a chain reaction in the brain that starts with a stressful stimulus and ends with the release of chemicals. The chemicals that are released cause your body to become tense and react to your surroundings and the thing that you fear. Some examples of what these chemicals cause is a racing heartbeat, fast breathing, and energized muscles. All of these reactions are caused without your consent. All these responses these chemicals cause are automatic. The sections of your brain related to responding to fear are the Thalamus, Sensory Cortex, Hippocampus, Amygdala, and Hypothalamus. Your Thalamus is responsible for deciding where to send income sensory data meaning whether to send it to your eyes, ears, mouth, hands, or other body parts. The Sensory Cortex interprets the sensory data to find out what it means. The Hippocampus stores and retrieves memories and processes sets of stimuli. The Amygdala decodes the emotion; it decides if you are feeling fear or not. It also determines if a possible threat is around you. The Amygdala also stores fear me memories. The last section of your brain that responds to fear is the Hypothalamus. The Hypothalamus determines whether to fight or flight. In other words, it determines whether you should stand up to the threat or to run away from the threat. This is how the brain responds to fear.

How Does the Brain See Things Around You?

    Your brain creates a picture of the things around you when it sees things, but in order to that, it has to add details in order to register some of the items. Some items it adds are movement, color, depth, and shape. Certain things can cause brain damage that causes the brain to not be able put the whole picture together. For example, agnosia is where you have trouble seeing things correctly such as thinking  a glove is a continuous surface enfolded upon itself. If your brain doesn't have a problem, it responds to edges to create an object. the color and shading of the object help the brain decipher what the item is. Each of your eyes sees a different picture. Your brain puts those two pictures together to create the finished product. this also tells how far away the object is. Enhancements such as shadows, textures and prior knowledge help tell how far away it is. Specific signals are sent to your brain to tell if an object is moving. Features such as makeup, hairstyle, thickness of eyebrows, and how much their nose sticks out helps the brain decide whether someone is a boy or girl. When seeing someone unfamiliar, your brain  automatically looks for things like gender, age, and race. this is how your brain sees the things around you.
