Santiago Ramón y Cajal Santiago Ramón y Cajal ForMemRS (Spanish: [sanˈtjaɣo raˈmon i kaˈxal]; 1 May 1852 – 18 October 1934) was a Spanish pathologist, histologist, neuroscientist and Nobel laureate. His original pioneering investigations of the microscopic structure of the brain have led him to be designated by many as the father of modern neuroscience. His medical artistry was legendary, and hundreds of his drawings illustrating the delicate arborizations of brain cells are still in use for educational and training purposes. Biography The son of physician and anatomy lecturer Justo Ramón and Antonia Cajal, Ramón y Cajal was born of Aragonese parents in Petilla de Aragón in Navarre, Spain. As a child he was transferred between many different schools because of his poor behavior and anti-authoritarian attitude. Over the summer of 1868, Cajal's father, hoping to interest his son in a medical career, took him to graveyards to find human remains for anatomical study. Works and theories
The brain needs downs to have ups Four neurochemicals cause happiness : endorphins, dopamine , oxytocin and serotonin. Each evolved to do a different job. When you know what the job is, you know why your happy chemicals can't be on all the time. 1. Endorphins evolved to mask pain. If you're escaping a predator, neurochemical euphoria promotes survival by mask pain until you're in a safe place. 2. Happy chemicals evolved to alert us to survival-relevant information around us. Yet it's natural to desire more happy chemicals and to do everything possible to stimulate them.

The fine dopamine line between creativity and schizophrenia | Sc New research shows a possible explanation for the link between mental health and creativity. By studying receptors in the brain, researchers at the Swedish medical university Karolinska Institutet have managed to show that the dopamine system in healthy, highly creative people is similar in some respects to that seen in people with schizophrenia. High creative skills have been shown to be somewhat more common in people who have mental illness in the family. "We have studied the brain and the dopamine D2 receptors, and have shown that the dopamine system of healthy, highly creative people is similar to that found in people with schizophrenia," says associate professor Fredrik Ullén from Karolinska Institutet's Department of Women's and Children's Health. "The study shows that highly creative people who did well on the divergent tests had a lower density of D2 receptors in the thalamus than less creative people," says Dr Ullén.
Khan Academy The dark side of Oxytocin August 1st, 2011 in Psychology & Psychiatry / For a hormone, oxytocin is pretty famous. It’s the “cuddle chemical”—the hormone that helps mothers bond with their babies. Salespeople can buy oxytocin spray on the internet, to make their clients trust them. It’s known for promoting positive feelings, but more recent research has found that oxytocin can promote negative emotions, too. Oxytocin’s positive effects are well known. But the warm fuzzy side of oxytocin isn’t the whole story. But Kemp and Guastella think oxytocin’s role is slightly different. If Kemp and Guastella are right, that could mean that oxytocin could also increase anger and other negative approach-related emotions. Further research will show more about what emotions are promoted by oxytocin, Kemp says. Provided by Association for Psychological Science
Eye Movement and Lying - How to detect lies Interesting Info -> Lying Index -> Eye Direction & Visual Accessing Cues Eye Movement and Direction & How it Can Reveal Truth or Lies This is a continuation of our previous article Detecting Lies. Many comments by our visitors asked about how eye direction can indicate the presence of a lie. Can the direction a person's eyes reveal whether or not they are making a truthful statement? In these shows a detective will deduce if a person is being untruthful simply because they looked to the left or right while making a statement.
