Brainport (Eindhoven)
BrainPort is a technology whereby sensory information can be sent to one's brain through an electrode array which sits atop the tongue. It was initially developed by Paul Bach-y-Rita as an aid to people's sense of balance, particularly of stroke victims. Bach-y-Rita founded ''Wicab'' in 1998. It has also been developed for use as a visual aid, demonstrating its ability to allow a blind person to see his or her surroundings in polygonal and pixel form. In this scenario, a camera picks up the image of the surrounding, the information is processed by a chip which converts it into impulses which are sent through an electrode array, via the tongue, to the person's brain. The human brain is able to interpret these impulses as visual signals and they are then redirected to the visual cortex, allowing the person to "see." This is similar in part to how a cochlear implant works, in that it transmits electrical stimuli to a receiving device in the body. The BrainPort V100 oral electro ...

Truman State University Index
The ''Truman State University Index'' is a weekly student newspaper distributed at Truman State University and throughout the Kirksville, Missouri community. The publication is entirely student-run and funded mostly through its own advertising revenue. It has published continuously since 1909, and its current circulation is about 4,500. The Index publishes about 14 issues per academic term for a total of 28 per year, on Thursdays, and does not publish when classes are not in session. An issue usually includes 20 pages. Membership Staff members of the Index attend conferences sponsored by the Society of Professional Journalists (SPJ) and College Media Advisers, Inc. and many belong to the Truman chapter of SPJ. Recognition The Index has won regional and national awards through SPJ and CMA, including the nationwide Apple Award by College Media Advisers in 2003, 2005, 2006, 2007 and 2009 in its category of best non-daily broadsheet newspaper and national Best in Show award, given ...

Paul Bach-y-Rita
Paul Bach-y-Rita (April 4, 1934 – November 20, 2006) was an American neuroscientist whose most notable work was in the field of neuroplasticity. Bach-y-Rita was one of the first to seriously study the idea of neuroplasticity (although it was first proposed in the late 19th century), and to introduce sensory substitution as a tool to treat patients with neurological disorders. Bach-y-Rita is known as "the father of sensory substitution". Biography Bach-y-Rita was born on April 4, 1934, in New York City to Anne Hyman and Pedro Bach-y-Rita, the latter a Catalan poet and teacher at City College of New York. He studied at the Bronx High School of Science, from which he graduated at the age of fifteen before studying at Mexico City College (now the University of the Americas in Puebla). After his early education, he studied medicine at Universidad Nacional Autónoma de México (UNAM). He initially dropped out, going through several varied jobs, but later returned to finish his deg ...

Senses
A sense is a biological system used by an organism for sensation, the process of gathering information about the world through the detection of stimuli. (For example, in the human body, the brain which is part of the central nervous system receives signals from the senses which continuously receive information from the environment, interprets these signals, and causes the body to respond, either chemically or physically.) Although traditionally five human senses were identified as such (namely sight, smell, touch, taste, and hearing), it is now recognized that there are many more. Senses used by non-human organisms are even greater in variety and number. During sensation, sense organs collect various stimuli (such as a sound or smell) for transduction, meaning transformation into a form that can be understood by the brain. Sensation and perception are fundamental to nearly every aspect of an organism's cognition, behavior and thought. In organisms, a sensory organ consist ...

Stroke
A stroke is a disease, medical condition in which poor cerebral circulation, blood flow to the brain causes cell death. There are two main types of stroke: brain ischemia, ischemic, due to lack of blood flow, and intracranial hemorrhage, hemorrhagic, due to bleeding. Both cause parts of the brain to stop functioning properly. Signs and symptoms of a stroke may include an hemiplegia, inability to move or feel on one side of the body, receptive aphasia, problems understanding or expressive aphasia, speaking, dizziness, or Homonymous hemianopsia, loss of vision to one side. Signs and symptoms often appear soon after the stroke has occurred. If symptoms last less than one or two hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke. A subarachnoid hemorrhage, hemorrhagic stroke may also be associated with a thunderclap headache, severe headache. The symptoms of a stroke can be permanent. Long-term complications may include pneumonia and Urinary incontin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cochlear Implant
A cochlear implant (CI) is a surgically implanted neuroprosthesis that provides a person who has moderate-to-profound sensorineural hearing loss with sound perception. With the help of therapy, cochlear implants may allow for improved speech understanding in both quiet and noisy environments. A CI bypasses acoustic hearing by direct electrical stimulation of the auditory nerve. Through everyday listening and auditory training, cochlear implants allow both children and adults to learn to interpret those signals as speech and sound. The implant has two main components. The outside component is generally worn behind the ear, but could also be attached to clothing, for example, in young children. This component, the sound processor, contains microphones, electronics that include digital signal processor (DSP) chips, battery, and a coil that transmits a signal to the implant across the skin. The inside component, the actual implant, has a coil to receive signals, electronics, and an ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Food And Drug Administration
The United States Food and Drug Administration (FDA or US FDA) is a List of United States federal agencies, federal agency of the United States Department of Health and Human Services, Department of Health and Human Services. The FDA is responsible for protecting and promoting public health through the control and supervision of food safety, tobacco products, caffeine products, dietary supplements, Prescription drug, prescription and Over-the-counter drug, over-the-counter pharmaceutical drugs (medications), vaccines, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation emitting devices (ERED), cosmetics, Animal feed, animal foods & feed and Veterinary medicine, veterinary products. The FDA's primary focus is enforcement of the Federal Food, Drug, and Cosmetic Act (FD&C), but the agency also enforces other laws, notably Section 361 of the Public Health Service Act, as well as associated regulations. Much of this regulatory-enforcement work is not d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sensory Substitution
Sensory substitution is a change of the characteristics of one sensory modality into stimuli of another sensory modality. A sensory substitution system consists of three parts: a sensor, a coupling system, and a stimulator. The sensor records stimuli and gives them to a coupling system which interprets these signals and transmits them to a stimulator. In case the sensor obtains signals of a kind not originally available to the bearer it is a case of sensory augmentation. Sensory substitution concerns human perception and the plasticity of the human brain; and therefore, allows us to study these aspects of neuroscience more through neuroimaging. Sensory substitution systems may help people by restoring their ability to perceive certain defective sensory modality by using sensory information from a functioning sensory modality. History The idea of sensory substitution was introduced in the 1980s by Paul Bach-y-Rita as a means of using one sensory modality, mainly taction, to gai ...

Neuroplasticity
Neuroplasticity, also known as neural plasticity, or brain plasticity, is the ability of neural networks in the brain to change through growth and reorganization. It is when the brain is rewired to function in some way that differs from how it previously functioned. These changes range from individual neuron pathways making new connections, to systematic adjustments like cortical remapping. Examples of neuroplasticity include circuit and network changes that result from learning a new ability, environmental influences, practice, and psychological stress. Neuroplasticity was once thought by neuroscientists to manifest only during childhood, but research in the latter half of the 20th century showed that many aspects of the brain can be altered (or are "plastic") even through adulthood. However, the developing brain exhibits a higher degree of plasticity than the adult brain. Activity-dependent plasticity can have significant implications for healthy development, learning, memor ...
