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. The advent of brain imaging revolutionized the field, allowing researchers to directly monitor the brain’s activities during experiments.
La neuroética About the Course “Perhaps a man really dies when his brain stops, when he loses the power to take in a new idea.” --George Orwell Neuroethics might well be the most rapidly growing area within bioethics; indeed, in some respects neuroethics has grown as an independent field, with its own journals, professional society and institutional centers. Bruxism Bruxism, also known as tooth grinding, is the excessive grinding of the teeth and/or excessive clenching of the jaw. It is an oral parafunctional activity; i.e., it is unrelated to normal function such as eating or talking. Bruxism is a common problem; reports of prevalence range from 8–31% in the general population. Bruxism may cause minimal symptoms, and therefore people may not be aware of the condition. Several symptoms are commonly associated with bruxism, including hypersensitive teeth, aching jaw muscles, and headaches.
Brain Surface and Tractography Viewer Surface Opacity: Surface Overlay Display Range: Histogram Min: Max: Minimum Track Length: The pial surface is the "outer" cortical surface and represents the boundary between gray matter and cerebrospinal fluid. Typically, it is the surface that comes to mind when visually thinking of a brain. 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.
Raynaud's phenomenon In medicine, Raynaud's phenomenon /reɪˈnoʊz/ or Raynaud phenomenon is excessively reduced blood flow in response to cold or emotional stress, causing discoloration of the fingers, toes, and occasionally other areas. This condition may also cause nails to become brittle with longitudinal ridges. Named after French physician Maurice Raynaud (1834–1881), the phenomenon is believed to be the result of vasospasms that decrease blood supply to the respective regions.
JCESOM Radiology Library The practice of medicine now requires physicians to understand and interpret digital images of body structure obtained by CT, MRI and ultrasound. Imaging technology has made major advances in increasing resolution and flexibility in visualization and three-dimensional reconstruction of the human body. The rapid expansion of digital data bases and systems has brought those images to the computers of doctors' offices. Interpretation of digital images requires detailed training in the anatomical sciences and is no longer limited to specialists. . Fundamentos cerebrales: Conozca a su cerebro: Instituto Nacional de Trastornos Neurológicos y Accidentes Cerebrovasculares (NINDS) Introduction The brain is the most complex part of the human body. This three-pound organ is the seat of intelligence, interpreter of the senses, initiator of body movement, and controller of behavior. Lying in its bony shell and washed by protective fluid, the brain is the source of all the qualities that define our humanity.
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 it is known that the brain seems to specialize in activity that requires Beta frequency brain waves during wakefulness, and Alpha frequency waves during sleep or meditation, and Theta waves during rage, and Delta waves in coma - no one is quite sure why.
