neurogenesis Neurotechnology Neurotechnology is any technology that has a fundamental influence on how people understand the brain and various aspects of consciousness, thought, and higher order activities in the brain. It also includes technologies that are designed to improve and repair brain function and allow researchers and clinicians to visualize the brain. Background The field of neurotechnology has been around for nearly half a century but has only reached maturity in the last twenty years. As the field’s depth increases it will potentially allow society to control and harness more of what the brain does and how it influences lifestyles and personalities. Current technologies Imaging Magnetic resonance imaging (MRI) is used for scanning the brain for topological and landmark structure in the brain, but can also be used for imaging activation in the brain. While detail about how MRI works is reserved for the actual MRI article, the uses of MRI are far reaching in the study of neuroscience.
Psicología Psi (Ψ), letra griega comúnmente asociada con la psicología. La psicología (también sicología, cuyo uso es menos frecuente) (literalmente «estudio o tratado del alma»; del griego clásico ψυχή, transliterado psykhé, «psique», «alma», «actividad mental», y λογία, logía, «tratado» o «estudio») es, a la vez, una profesión, una disciplina académica y una ciencia que trata el estudio y análisis de la conducta y los procesos mentales de los individuos y grupos humanos en distintas situaciones,     cuyo campo de estudio abarca todos los aspectos de la experiencia humana y lo hace para fines tanto de investigación como docentes y laborales, entre otros. Por medio de sus diversos enfoques, la psicología explora conceptos como la percepción, la atención, la motivación, la emoción, el funcionamiento del cerebro, la inteligencia, el pensamiento, la personalidad, las relaciones personales, la conciencia y la inconsciencia.

Brain Waves The human brain is more complex than your scientists suspect. They are busily mapping where certain functions occur, and how parts of the brain activate in syncronicity. They know that parts of the brain, near the stem, are older than, for instance, the forebrain, and that a human can survive remarkably well with only half a brain, as long as that half is either the right or left, intact. But what your scientists do not know is that beyond the old brain and the new, the subconscious and the conscious, the right and the left halves - there are yet more subdivisions of the human brain. Where brain functions are localized close to the data stores, the chemical paths and links that constitute memory and the potential for thought, these functional mother lodes cannot be mined without the greased lightning that is the communication substrata. Brain waves are but a symptom of the process, whereby the brain, as an organ, hums to itself. All rights reserved: ZetaTalk@ZetaTalk.com
Brain Atlas - Introduction The central nervous system (CNS) consists of the brain and the spinal cord, immersed in the cerebrospinal fluid (CSF). Weighing about 3 pounds (1.4 kilograms), the brain consists of three main structures: the cerebrum, the cerebellum and the brainstem. Cerebrum - divided into two hemispheres (left and right), each consists of four lobes (frontal, parietal, occipital and temporal). – closely packed neuron cell bodies form the grey matter of the brain. Cerebellum – responsible for psychomotor function, the cerebellum co-ordinates sensory input from the inner ear and the muscles to provide accurate control of position and movement. Brainstem – found at the base of the brain, it forms the link between the cerebral cortex, white matter and the spinal cord. Other important areas in the brain include the basal ganglia, thalamus, hypothalamus, ventricles, limbic system, and the reticular activating system.

Brain Structures and Their Functions The nervous system is your body's decision and communication center. The central nervous system (CNS) is made of the brain and the spinal cord and the peripheral nervous system (PNS) is made of nerves. Together they control every part of your daily life, from breathing and blinking to helping you memorize facts for a test. Nerves reach from your brain to your face, ears, eyes, nose, and spinal cord... and from the spinal cord to the rest of your body. Sensory nerves gather information from the environment, send that info to the spinal cord, which then speed the message to the brain. The brain then makes sense of that message and fires off a response. The brain is made of three main parts: the forebrain, midbrain, and hindbrain. The Cerebrum: The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. What do each of these lobes do? Note that the cerebral cortex is highly wrinkled.
Brain Awareness Week 2015: How Brain Research Has Progressed, And Ways You Can Enhance Cognition Twenty years ago, the Dana Alliance for Brain Initiatives launched Brain Awareness Week (BAW) — March 16 to 22 — in the U.S. to celebrate and increase the public’s awareness of the progress and benefits of brain research. What began as a partnership with 160 organizations stateside has now expanded to thousands of organizations and hundreds of countries across the globe. Why then, is a growing global campaign still unknown to so many, its reach not quite on par with, say, heart health and sleep? “I think brain health is lagged behind,” neuroscientist Dr. Deborah Yurgelun-Todd, of The Brain Institute at the University of Utah, told Medical Daily. “Where other areas of health research have made advances, we haven’t had as many good solutions to problems. Hard but not impossible, considering the “unbelievable advances” brain imaging tools have made in the last few decades. “I think people are less worried of dying of a heart attack and more worried with living with dementia,” she said.
Tecnología Educativa Neuropsychology Neuropsychology studies the structure and function of the brain as they relate to specific psychological processes and behaviors. It is seen as a clinical and experimental field of psychology that aims to study, assess, understand and treat behaviors directly related to brain functioning. The term neuropsychology has been applied to lesion studies in humans and animals. In practice neuropsychologists tend to work in research settings (universities, laboratories or research institutions), clinical settings (involved in assessing or treating patients with neuropsychological problems), forensic settings or industry (often as consultants where neuropsychological knowledge is applied to product design or in the management of pharmaceutical clinical-trials research for drugs that might have a potential impact on CNS functioning). History Imhotep The study of the brain can be linked all the way back to around 3500 B.C. Hippocrates René Descartes Thomas Willis
Science: A New Map of the Human Brain Who hasn't heard that people are either left-brained or right-brained—either analytical and logical or artistic and intuitive, based on the relative "strengths" of the brain's two hemispheres? How often do we hear someone remark about thinking with one side or the other? A flourishing industry of books, videos and self-help programs has been built on this dichotomy. You can purportedly "diagnose" your brain, "motivate" one or both sides, indulge in "essence therapy" to "restore balance" and much more. Everyone from babies to elders supposedly can benefit. The left brain/right brain difference seems to be a natural law. Except that it isn't. The origins of this myth lie in experimental surgery on some very sick epileptics a half-century ago, conducted under the direction of Roger Sperry, a renowned neuroscientist at the California Institute of Technology. Our theory's roots lie in a landmark report published in 1982 by Mortimer Mishkin and Leslie G. Messrs.
Researchers show that memories reside in specific brain cells Our fond or fearful memories — that first kiss or a bump in the night — leave memory traces that we may conjure up in the remembrance of things past, complete with time, place and all the sensations of the experience. Neuroscientists call these traces memory engrams. But are engrams conceptual, or are they a physical network of neurons in the brain? In a new MIT study, researchers used optogenetics to show that memories really do reside in very specific brain cells, and that simply activating a tiny fraction of brain cells can recall an entire memory — explaining, for example, how Marcel Proust could recapitulate his childhood from the aroma of a once-beloved madeleine cookie. In that famous surgery, Penfield treated epilepsy patients by scooping out parts of the brain where seizures originated. Fast forward to the introduction, seven years ago, of optogenetics, which can stimulate neurons that are genetically modified to express light-activated proteins. False memory
Eating green leafy vegetables keeps mental abilities sharp -- ScienceDaily Something as easy as adding more spinach, kale, collards and mustard greens to your diet could help slow cognitive decline, according to new research. The study also examined the nutrients responsible for the effect, linking vitamin K consumption to slower cognitive decline for the first time. "Losing one's memory or cognitive abilities is one of the biggest fears for people as they get older," said Martha Clare Morris, Sc.D., assistant provost for community research at Rush University Medical Center and leader of the research team. "Since declining cognitive ability is central to Alzheimer's disease and dementias, increasing consumption of green leafy vegetables could offer a very simple, affordable and non-invasive way of potentially protecting your brain from Alzheimer's disease and dementia." "Our study identified some very novel associations," said Morris, who will present the research at the American Society for Nutrition (ASN) Annual Meeting during Experimental Biology 2015.
The First Real Reason We Need To Sleep We know we need to sleep. We know our brains and bodies work better after sleep. But what we didn't know, until now, was why. Scientists have just reported the first major mechanical reason our brains need to sleep — certain cleaning mechanisms in the brain work better when we shut the brain down. Just like how dump trucks take to the city streets during the pre-dawn hours because there's less traffic, our brain's cleaners also work best when there's less going on. "This study shows that the brain has different functional states when asleep and when awake," study researcher Maiken Nedergaard, of the University of Rochester said in a statement. We've known that our brains consolidate memories during sleep and perform other important functions. We know that sleep has all of these benefits, but until now we didn't know any of the specific changes that bring about these sleep benefits. The paper was published in the journal Science on Oct. 17. Toxic cells J. Sleeping mice Understanding sleep
