Santiago Ramón y Cajal Santiago Ramón y Cajal ForMemRS[1] (Spanish: [sanˈtjaɣo raˈmon i kaˈxal]; 1 May 1852 – 18 October 1934)[2] 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.[3] Biography[edit] The son of physician and anatomy lecturer Justo Ramón and Antonia Cajal, Ramón y Cajal was born of Aragonese parents in Petilla de Aragón[2] 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[edit]
An afternoon nap markedly boosts the brain’s learning capacity If you see a student dozing in the library or a co-worker catching 40 winks in her cubicle, don’t roll your eyes. New research from the University of California, Berkeley, shows that an hour’s nap can dramatically boost and restore your brain power. Indeed, the findings suggest that a biphasic sleep schedule not only refreshes the mind, but can make you smarter. Students who napped (green column) did markedly better in memorizing tests than their no-nap counterparts.

In the recent UC Berkeley sleep study, 39 healthy young adults were divided into two groups — nap and no-nap.
RadioBlagon Khan Academy The Brain's Dark Energy Imagine you are almost dozing in a lounge chair outside, with a magazine on your lap. Suddenly, a fly lands on your arm. You grab the magazine and swat at the insect. What was going on in your brain after the fly landed? It turns out that when your mind is at rest—when you are daydreaming quietly in a chair, say, asleep in a bed or anesthetized for surgery—dispersed brain areas are chattering away to one another.

Forestiers par nature : ONF Forestiers par nature : le forestier naturaliste Claude Lagarde est forestier naturaliste à l'ONF : « Nous œuvrons pour pérenniser ces milieux et pour que les espèces qui vivent dans les forêts continuent d’être observées par nos successeurs. » Seen 25209 times Le forestier naturaliste : - réalise des inventaires de la faune et de la flore - participe à la préservation des milieux naturels - échange avec le monde scientifique et associatif. Chaque jour, les femmes et les hommes qui travaillent à l’ONF assurent le renouvellement des forêts publiques, participent au développement de la filière bois, veillent sur la biodiversité et vous accueillent. L'ONF a réalisé une série de portraits de forestiers pour découvrir les différentes facettes de leurs métiers et comprendre comment les forêts publiques sont gérées durablement.

Is the Internet Warping Our Brains? - Technology Is this a bad thing? Not necessarily, says Sparrow. For instance, for years people in the educational community have known that rote learning—that is, forcing children to memorize facts and dates—is a poor way to educate. If that's the case, allowing computers to do some of the memorizing for us might be a way to focus more on the more philosophical aspects of learning. "Perhaps those who teach in any context, be they college professors, doctors or business leaders, will become increasingly focused on imparting greater understanding of ideas and ways of thinking, and less focused on memorization," Sparrow told Time. Of course, while you might think that this research suggests people on the internet are using less of their brains than those not online, you'd be wrong.
Eskeletons How to increase serotonin in the human brain without drugs La Cellule Animale The Brain-Information about the Brain 1 Introduction “I think, therefore I am.” —René Descartes, 17th-century philosopher Few of us question the crucial importance of the brain. The brain makes up only 2 percent of our body weight, but it consumes 20 percent of the oxygen we breathe and 20 percent of the energy we consume. Scientists have worked for many years to unravel the complex workings of the brain. Despite these and other significant advances in the field of brain research, most of the processes responsible for the integrated functioning of billions of brain cells remain a mystery. An essential aspect of any scientific research is communicating results to the public in a way that is easily understood. To correctly interpret the information transmitted through these venues, we need a better understanding of basic concepts related to the brain. 2 Myths and Realities about the Brain As a result of the misinformation presented by various media, many people maintain misconceptions about the brain and brain function.
Neuroscience of Music - How Music Enhances Learning - Neuroplasticity Neuroscience research into the neuroscience of music shows that musicians’ brains may be primed to distinguish meaningful sensory information from noise. This ability seems to enhance other cognitive abilities such as learning, language, memory and neuroplasticity of various brain areas. Scientific review of how music training primes nervous system and boosts learning Those ubiquitous wires connecting listeners to you-name-the-sounds from invisible MP3 players, whether of Bach, Miles Davis or, more likely today, Lady Gaga, only hint at music’s effect on the soul throughout the ages. Now a data-driven review by Northwestern University researchers that will be published July 20 in Nature Reviews Neuroscience pulls together converging research from the scientific literature linking musical training to learning that spills over to skills including language, speech, memory, attention and even vocal emotion.
