“Severe stress hurts children’s brains, hurts hippocampus, study shows.” Krista Conger Stanford Report. March, 2007. http://news.stanford.edu/news/2007/march7/med-carrion-030707.html

In this article, Victor Carrion did a study on children and how stress affects their brains. He studied 15 children from the ages of 7-13 that were suffering from PTSD for a 12-18 month period to see how they cope with stress and who copes better. In this study, they found that kids with higher cortisol levels (a marker level of stress) and more severe PTSD syndromes at the beginning of the study were more likely to have reductions in their hippocampal levels than their peers, who were not as affected. It is shown that the decrease in hippocampal levels is related to the increase in stress and cortisol levels. The cortisol is also proven to decrease the hippocampal size, which then makes it harder to cope and increasing cortisol levels, again decreasing the size. It is a viscous cycle. It is shown that children with more damage to their hippocampal levels at a young age will have a harder time dealing with large amounts of stress later in their life.

“The Teen Brain: It’s Just Not Grown Up Yet.” Richard Knox NPR. March, 2010. http://www.npr.org/templates/story/story.php?storyId=124119468

This article explains why teenagers are worse at making decisions and how the connection to the frontal lobe can have other effects on us as well. The frontal lobe is the part of the brain that controls decision making. Some may think that teenagers can’t access it as well, they can, it just happens slower. The myelin sheaths that surround the axons on the neurons are not as developed in that area, making the neural communications slower to the frontal lobe. This slower connection means

explanation is the serotonin and dopamine neurotransmitters and how they affect our aggression; the hormonal mechanisms are the testosterone and cortisol chemicals. Testosterone is a hormone that is more concentrated in men than in women as it is a male sex hormone, it is thought to influence aggression from a young age onwards, due to its actions on the brain areas involved in controlling aggression.

experiences throughout their life If this explanation is valid then we would expect a higher rate of depression amongst genetically similar relatives of sufferer because of genetic predisposition. GENETIC EXPLANATIONS Family studies select people who already have depression and examine whether other members of their family have been, or might be, diagnosed with depression.

How Music Affects Brain

help prevent seizers, and even help repair the brain. Music is a powerful ally for modern medicine and affects the brain in interesting ways. To better understand how music affects the brain, scientists have observed the brain of a musician compared to that of a normal person for physical differences. Some quite interesting discoveries were maid from this discovery such as a musician’s brain is more symmetrical than a normal person. “Areas of the brain responsible for motor control, auditory processing…

Delta Brainwave Patterns

electroencephalography (EEG)—which the human brain assumes during different stages of development, stimulation, and consciousness. Between 0.1 to 4 hertz, Delta brainwaves are the slowest yet deepest frequency of six dominant brainwaves measured in humans. These patterns first appear in infancy but remain crucial through adulthood adulthood, where they're primarily detected in states of deep, dreamless sleep, bodily healing, and unconscious memory formation. Each brain is unique and hews to certain brainwave…

Laboratory (NREL) PRODUCTIVITY AND ATTENDANCE A school with insufficient light can also reduce a student’s ability to learn due to the effect lighting has on the brain. Poor spectral light can create strain on students’ eyes, leading to a decrease in information processing and learning ability, as well as causing higher stress levels (Liberman 1991). Dr. Walker (1998) found that stress impacts…
