1. 3.The brain can be strengthened through exercise.

1.1. The article about exercising the brain states,"The brain is made up of cells called neurons, which are connected to each other by links called synapses... Cotman’s work has shown that in older rodents, exercise increases the number of synapses and stimulates the brain to develop more neurons" (Deardoff).

1.2. A video about music's effect on the brain explains that, "[c]hildren that had at least three years of instrumental music training," (exercising the brain),"performed better than their non-musical counterparts in a variety of tests... decoding written music might increase reading ability and visual pattern recognition" (Fantano).

2. 2.negative effects of marijuana

2.1. an article about marijuana's effect on the brain argues,"In particular, the study identified changes to the nucleus accumbens and the nucleus amygdala, regions of the brain that are key to regulating emotion and motivation, in marijuana users who smoke between one and seven joints a week" (Dobuzinskis).

2.2. While describing "marijuana disorder," another negative effect on the brain, the second article states,"About 4 percent of adults between 2001 and 2002 reported having used marijuana in the past year, compared to about 10 percent between 2012 and 2013. Similarly, 1.5 percent had abuse or dependence problems - so-called marijuana use disorder - at the start of the 21st Century, compared to about 3 percent from 2012 to 2013" (Seaman).

3. 1.stress' negative effects

3.1. Displaying the truth that stress causes anger and furthermore confusion, the article about being 'hangry' states,"'In a brain lacking glucose, it’s harder to control signs of anger. Acute bouts of hunger trigger the release of stress hormones which makes it harder to manage our anger and irritability'" (Ahmed, "Being Hangry Is Normal").

3.2. An article on stress' effect on the body explains, "Known as 'fight or flight,' the stress response evolved to help us survive. But it is also triggered by events that aren’t life-threatening. This can include academic and relationship pressures, or even stress from being over-connected to technology and social media" ("Stressed Out?" 30-31).

4. 4.concussions

4.1. In Phineas Gage there is a vivid description of what a concussion is and its effect on the brain. The story states, "A hard blow to the head can rattle the brain around inside like a BB in a tin can. The rattling bruises the brain, and bruised tissue swells. The brain swells, but the skull stays the same size. A swollen brain can jam itself so tightly it will cut off its own blood supply. This swelling can choke off oxygen to parts of the brain long enough to cause permanent damage. It can also cause death" (Fleischman 9-10).

4.2. Concussions are very dangerous to the brain partially because people don't recognize them as serious medical issues and check with their doctors about them. The article about sport and head injuries explains,"The CDC has estimated that up to 3.8 million concussions occur in sports and recreational activities each year. However, some experts wonder if those numbers underestimate total brain injuries. Some individuals may not seek treatment for mild or moderate symptoms" (Vertuno).

5. 5.Importance of different areas are the brain.

5.1. In describing the function of the brain stem, the video about the different parts of the brain and their function explains,"It's going to keep your um self breathing, keep circulation going, and digestion, swallowing. All of this is going to be controlled by the brain stem" (Jolly).

5.2. The article about Einstein's brain explains the function of the corpus Callosum saying,"A dense network of neural fibers, the corpus callosum stretches nearly the full length of the brain from behind the forehead to the nape of the neck. It carries electrical signals between the brain’s right and left hemispheres, making brain regions with very different functions work together" (Healy).

6. 6.adaptability

6.1. The article about lies and their effect on the brain explains,"The scientists assert that the reduction in amygdala activity was a result of 'emotional adaptation,' which causes neural responses to repeated stimuli to decline over time. 'The first time you cheat on your taxes, for example, you might feel quite bad about it,' Sharot said. 'But the next time you cheat, you have already adapted, and there is less of a negative reaction to hold you back — and you might lie more'" (Mantha).

6.2. In regards to the improvement of the brain in ADHD patients, the article about using video games to possibly help ADHD patients states,"Eddie Martucci, the co-founder of Akili, says the hope is that 'when you engage in the game pretty intensely for long periods of time, it actually reconditions how the brain processes information”' (Landhuis).
