In mammalian brain anatomy, the prefrontal cortex (PFC) is the cerebral cortex which covers the front part of the frontal lobe. The PFC contains Brodmann areas 9, 10, 11, 12, 46, and 47.
Many authors have indicated an integral link between a person's personality and the functions of the prefrontal cortex. This brain region has been implicated in planning complex cognitive behavior, personality expression, decision making, and moderating social behaviour. The basic activity of this brain region is considered to be orchestration of thoughts and actions in accordance with internal goals.
The most typical psychological term for functions carried out by the prefrontal cortex area is executive function. Executive function relates to abilities to differentiate among conflicting thoughts, determine good and bad, better and best, same and different, future consequences of current activities, working toward a defined goal, prediction of outcomes, expectation based on actions, and social "control" (the ability to suppress urges that, if not suppressed, could lead to socially unacceptable outcomes).
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.
Robert Morris Sapolsky (born 1957) is an American neuroendocrinologist, professor of biology, neuroscience, and neurosurgery at Stanford University, researcher and author. He is currently a professor of biological sciences, and professor of neurology and neurological sciences and, by courtesy, neurosurgery, at Stanford University. In addition, he is a research associate at the National Museums of Kenya.
Sapolsky was born in Brooklyn, New York to immigrants from the Soviet Union. He was raised as an Orthodox Jew and spent his time reading about and imagining living with silverback gorillas. By age 12, he was writing fan letters to primatologists. He attended John Dewey High School and, by that time, he was reading textbooks on the subject and teaching himself Swahili.
Sapolsky describes himself as an atheist. He stated in his acceptance speech for the Emperor Has No Clothes Award in 2003, "I was raised in an Orthodox (Jewish) household, and I was raised devoutly religious up until around age 13 or so. In my adolescent years, one of the defining actions in my life was breaking away from all religious belief whatsoever."
The limbic system (or paleomammalian brain) is a complex set of brain structures located on both sides of the thalamus, right under the cerebrum. It is not a separate system but a collection of structures from the telencephalon, diencephalon, and mesencephalon. It includes the olfactory bulbs, hippocampus, amygdala, anterior thalamic nuclei, fornix, columns of fornix, mammillary body, septum pellucidum, habenular commissure, cingulate gyrus, parahippocampal gyrus, limbic cortex, and limbic midbrain areas.
The limbic system supports a variety of functions including epinephrine flow, emotion, behavior, motivation, long-term memory, and olfaction. Emotional life is largely housed in the limbic system, and it has a great deal to do with the formation of memories.
Although the term only originated in the 1940s, some neuroscientists, including Joseph LeDoux, have suggested that the concept of a functionally unified limbic system should be abandoned as obsolete because it is grounded mainly in historical concepts of brain anatomy that are no longer accepted as accurate.
Crash Course (also known as Driving Academy) is a 1988 made for television teen film directed by Oz Scott.
Crash Course centers on a group of high schoolers in a driver’s education class; many for the second or third time. The recently divorced teacher, super-passive Larry Pearl, is on thin ice with the football fanatic principal, Principal Paulson, who is being pressured by the district superintendent to raise driver’s education completion rates or lose his coveted football program. With this in mind, Principal Paulson and his assistant, with a secret desire for his job, Abner Frasier, hire an outside driver’s education instructor with a very tough reputation, Edna Savage, aka E.W. Savage, who quickly takes control of the class.
The plot focuses mostly on the students and their interactions with their teachers and each other. In the beginning, Rico is the loner with just a few friends, Chadley is the bookish nerd with few friends who longs to be cool and also longs to be a part of Vanessa’s life who is the young, friendly and attractive girl who had to fake her mother’s signature on her driver’s education permission slip. Kichi is the hip-hop Asian kid who often raps what he has to say and constantly flirts with Maria, the rich foreign girl who thinks that the right-of-way on the roadways always goes to (insert awesomely fake foreign Latino accent) “my father’s limo”. Finally you have stereotypical football meathead J.J., who needs to pass his English exam to keep his eligibility and constantly asks out and gets rejected by Alice, the tomboy whose father owns “Santini & Son” Concrete Company. Alice is portrayed as being the “son” her father wanted.
A very brief outline of the prefrontal cortex.

This talk was given at a local TEDx event, produced independently of the TED Conferences. Why is there a stigma associated with our brain's health? Consider that the brain is the most powerful, most staggeringly complex electro-biochemical machine ever created. Above and behind our eyes are 100 billion neurons in a small calcium shell, laced with organic pumps, channels and switches. Until recently, this complicated organ was thought to be static and unchangeable. Far from it. Learn from Dr. Sandra Bond Chapman, founder and chief director of the Center for BrainHealth at The University of Texas at Dallas seven scientifically-validated secrets anyone can implement to improve brain performance.

Mentioning of Prefrontal Cortex in Qur'an
Thanks to MRI and fMRI bran scans, we now know much more about how damage to or deficiencies in certain parts of the brain may underlie "evil" behavior. Topic: The neurobiology of evil Michael Stone: For a long time, people wondered: "Is there something different about the brain of somebody who does violent acts, particularly repetitive violent acts in comparison to an ordinary person's brain?" But not very much was known about it until the last maybe 15-20 years, particularly as we entered the era of the Magnetic Resonance Imaging. And with MRI and functional Magnetic Resonance Imaging where you're actually are taking pictures of the brain as the person is looking at some picture or hearing certain words and showing how the brain blood flow differs from moment to moment, now we really...

Stanley Center & Poitras Center Translational Neuroscience Joint Seminar Speaker: Amy Arnsten, Yale University December 1, 2015 The newly evolved circuits of the primate dorsolateral prefrontal cortex (dlPFC) generate the mental representations needed for working memory, the foundation of abstract thought. These layer III dlPFC pyramidal cell microcircuits are a focus of pathology in cognitive disorders such as schizophrenia and Alzheimer’s Disease. Research in the Arnsten lab has found that these circuits are uniquely regulated at the molecular level in ways that facilitate mental flexibility but make them particularly vulnerable to atrophy and degeneration. For example, in contrast to the primary visual cortex where calcium-cAMP signaling strengthens connections and increases neuronal ...
