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.
How to increase serotonin in the human brain without drugs 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. In reality, it would be foolish to make such a snap judgment without further investigation... but the technique does have some merit. So, here it is... read, ponder and test it on your friends and family to see how reliable it is for yourself. Visual Accessing Cues - "Lying Eyes" When asked a question a "normally organized" right-handed person looks (from your viewpoint, looking at them): The Gist of it... How this information is used to detect lies: Final Notes:
Two drugs show best treatment possibility for MS In massive news for neurology, The New England Journal of Medicine has published three important studies reporting that two new drugs for multiple sclerosis are more effective than existing treatments and can be taken in pill form. Multiple sclerosis is a bitch. It’s a neurological disorder where the immune system starts attacking myelin – the protective covering of nerves in the brain and spinal cord – leading to unpredictable attacks that typically leave the person a little more disabled each time. Problems can include movement difficulties, chronic pain, fatigue, cognitive problems, mood instability and impairments to the body’s automatic processes like digestion, bladder and bowel control. One problem with the the current treatments that try and slow down the disease itself, rather than just manage the effects, is that they all require regular injections or infusions via a drip. The studies that investigated these drugs were very impressive.
How the Brain Stops Time One of the strangest side-effects of intense fear is time dilation, the apparent slowing-down of time. It's a common trope in movies and TV shows, like the memorable scene from The Matrix in which time slows down so dramatically that bullets fired at the hero seem to move at a walking pace. In real life, our perceptions aren't keyed up quite that dramatically, but survivors of life-and-death situations often report that things seem to take longer to happen, objects fall more slowly, and they're capable of complex thoughts in what would normally be the blink of an eye. Now a research team from Israel reports that not only does time slow down, but that it slows down more for some than for others. An intriguing result, and one that raises a more fundamental question: how, exactly, does the brain carry out this remarkable feat? Researcher David Eagleman has tackled his very issue in a very clever way . Was it scary enough to generate a sense of time dilation?
