Human genome, twin study, genetic testing
determine sequences of the 3 billion chemical base pairs that make up human DNA, store this information in databases, improve tools for data analysis. Imagine how many diseases can be cured from this, never before. A normal gene may be inserted into a nonspecific location within the genome to replace a nonfunctional gene. This approach is most common.
Twins:
By studying twins and siblings and their families, we can estimate how genes and environment interact to influence character, strengths, vulnerabilities and values. Beginning in 2000, the MTFS enrolled an additional 500 pairs of twins and their parents into the MCTFR.

from Psychology / Psychiatry News From Medical News Today
Black cancer patients report having poorer physical and social well-being than their white counterparts but better emotional well-being, according to a study published in the November issue of the Journal of Pain and Symptom Management, Reuters Health reports. Previous studies have indicated that blacks have poorer physical health than whites.
Sleeping In School
from Psychology / Psychiatry News From Medical News Today
Up to 10% of children starting school suffer from sleep disturbances and these may lead to poor performance or behavioral difficulties. In the current edition of Deutsches Arzteblatt International, the child and adolescent psychiatrist Gerd Lehmkuhl and his colleagues present the results of a study from Cologne, Germany. The authors have as yet interviewed 1388 children starting school and their parents from all parts of Cologne.

WATCHING DEATH!
Scientists think death is the end of personal consciousness. Religious people think that their spirits and souls live on. Near-death-experience people claim that they "travel down a long tunnel of light, looking down their body." These are caused by disorganized brain signals while on the verge of dying. The most important experiment that’s never been done is to take fMRI or PET scans of people as they die.

VORB video & reading
It surprised me to see a bunch of mice injected with all sorts of drugs to keep them high (hence mouse party, haha.) I selected the mouse with cocaine in it and put it in a centrifuge machine thing. The machine shows the dopamine inside the mouse's brain. Dopamine is responsible for movement, emotion, and attention. With cocaine inside the mouse's body, it blocks the dopamine transporters from receiving dopamine to the neuron. Lacking of dopamine, a person can get Parkinson's disease this way. The mouse's brain is also similar to a human's brain, so if a person consumes cocaine they will not get enough dopamine inside the brain to their body. Also, a person with cocaine cannot control their movements, so they will not stay still.
Heroine mouse: Body's natural opiate blocks the inhibitory receptor so that dopamine can get out freely. This acts as a natural mood-enhancer like sudden overwhelm of happiness or natural painkiller. Heroin users can feel "good" when the heroin mimics natural opiates, making dopamine to flow out and makes a person feel better when in their down times or has an injury. Although frequent use of heroin will lead to depression if not enough dopamines can get out anymore without the heroin's aid.
Meth mouse: Meth mimics dopamine, can get in the neurons. Meth will force dopamines to get out of their vesicles. Excess dopamine are trapped in the synapses. Therefore, those dopamines will overstimulate the cell, making the person feel intense pleasure.
Your iBrain: How Technology Changes the Way We Think
The brain is adapted to change within the environment. An older person might think of newspaper and jazz or R&B music, while a hip and younger person might think of techno, rap and computer. Therefore, the brain only processes what the person has been exposed to the most (mere exposure can work here too.) Also, younger generations have better experience with computers than older generations because they grow up exposed to these sorts of information that older people don't have back then. For example, taking notes can never be easier with advanced electronic notepads. Whereas taking notes the old fashion way on paper might deem useful decades ago, but not anymore. However, a lady with an old, ragged notebook might have a better chance of keeping it longer than a man with his Blackberry phone which one day he will eventually drop and ruin it. Also, the brain has this plasticity that allows it to change information at will to adapt to different environments. For example, a boy who lives on a farm will eventually adapt to the city life, but it takes time.

http://www.blogger.com/www.learner.org/resources/series150.html The Mind
What I found: The brain's natural Morphine, or pain reliever, is Endorphins. Those soldiers during the Vietnam War used heroin because they were under a lot of stress during battle. This relieved them of emotional pain as well as physical pain when they got injuries and there were no hospitals near by. Sometimes when you get cuts and bruises you don't notice them instantly because endorphins is also released out at the same time to ease the pain. A while later you will notice the pain after the endorphins calm down. I also get cuts and bruises that I don't notice until later a sharp pain kicks in. One example of this is when I cut my knee on a glass table I didn't feel the pain. A moment later I noticed the blood trickling down, that's when I began to cry/scream/bawl (I was 9.) Maybe the image of blood made me think of pain or the pain itself, I'm not sure. Morphine can replace endorphins and vice versa. Therefore, people who use heroin will stop their process of making endorphins in the brain, so if they stop using heroin they will feel pain.
Understanding the Brain Through Epilepsy
The boy's brain neurons switch on and off uncontrollably, resulting in seizures, or spasms of muscles. Patients with seizures often forget what they recently did when asked. I saw the doctors performing a brain surgery (which is pretty gross...). They can remove a part of the brain that causes Ashley's seizures, cool :).
Brain to Muscle Link in the Monkey http://www.blogger.com/scienceblogs.com/purepedantry/2008/10/brain_to_muscle_link_in_the_mo.php
Even without access to the wrist, the monkey still responds to the game that involves his wrist by using brain neurons. One neuron can connect to other specific parts and muscles of the monkey's body to make them work. Therefore, the monkey can use that one neuron to move his wrist without actually using his wrist. Other neurons overtime can copy that action and move his wrist also, not just that one neuron. This could be useful for making synthetic limbs when one person damages a neuron, the doctor can replace that neuron with another neuron that does the same job.

The Mirror Neuron Revolution: Explaining What Makes Humans Social
Mirror neurons are located in the premotor cortex and inferior parietal cortex in the brain. They both activate when an action takes place. Mirror neurons can mimic action of another person or recognizing our own. For example, someone smiles at you, you smile back. People with autism process other people's emotions much slower. Therefore, they have a hard time to be sociable. Social people are the ones who respond to another's feelings and emotions (otherwise they're antisocial.) Mirror neurons are also important in language because we mimic our mother's sound and voice and try to repeat back the words we hear. This is why children need to stay in school so that they can learn positive things from their elders. Also, Lehrer shows that we can mimic other people's actions through movies and music, so bad movies and bad music can influence gang activities and violence in youth.

Aggression, Attraction, Conflict, Altruism
Conflict: I usually have conflicts with my older sister. Sometimes she wants me to take AP classes either to torture me or to help me going to a good college... Whenever I'm watching a TV show I like, she comes up and changes the channel. This is called a social trap since she wants to watch something against my liking for her own benefit. My sister complains when I spent like 10$ on a shirt while she spends 300$ on a new lap top and that's ok since it's for school work and hw :D. This just-world phenomenon leads to me believing that there's only some justice in the world.

Video, Outside Readings, Experiments
Video games link to violence? Gameplays are social activities for boys while girls socialize in real life. Although girls play less video games than boys on a weekly basis, a girl is more prone to physical fights than boys when exposed to M-rated games. This leads to anger and aggression in youth. Limit play time to 1-2 hrs a day.
Cults are groups that recruit weak-minded, depressed, or traumatized people to do strange actions for them. There are political cults, therapy cults, and business cults. Cults tend to realize things that are not real, and convince people to do so. Also, cults want people to get rid of their normal thinking. Example is the book 1984 by George Orwell whereas the leader took control over the citizens and make them think that they have freedom but they don't, and 2+2 =5. Therefore, we have to be careful when exposing to a cult and one asks us to join.
Cognitive Control: The ability to create subjective realities for oneself, or as directed by a leader.
Pygmalion Effect: Positive change of a person's performance or perception of a situation, based on expectation and encouragement by others.
Thought-Stopping: A behavior modification technique in which independent thinking is discouraged or disallowed

Stanford Prison
People would go crazy or isolated. They would have mindshock, and feel that 1 day is as long as 1 year. They would stare and sit at one spot all the time.
d. At first push-ups were not a very aversive form of punishment, but they became more so as the study wore on. Why the change?
At first, the body is kinda used to do push up, but as time goes on the body's muscles become weaker in prison so push ups will be harder to do. The guards or other prisoners step on the prisoner's back while he's doing push up. Also, the push up count is increased to several hours later on. Push up is also used in Nazi camps as punishment.

Memory test
They asked me to remember which flower is in which position that "hides the bee" in each different set of 2 flowers. The point of this research is to test out my memory to see if I still remember which flower belongs to which group. I had it right most of the time. Conclusion is if the same images occur over time, people will have a better chance of grasping them and get them right than just one time.

Sometimes it helps to group things separately instead of trying to learn them at once, as Ebbinghaus showed.
Proactive interference: old info overlapping new info. Example: me learning new language sometimes I use words from my other language into context. When I start playing a new game then come back to the old one I forget its key configs, thinking they're the same as the old one's but they're not.
Retroactive interference: new info overlaps old info: after learning English, I kinda forgot some of my root language.
