Sensory substitution

Sensory substitution means to transform the characteristics of one sensory modality into stimuli of another sensory modality. It is hoped that sensory substitution systems can help handicapped people by restoring their ability to perceive a certain defective sensory modality by using sensory information from a functioning 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. History[edit] Physiology of sensory substitution[edit] In a regular visual system, the data collected by the retina is converted into an electrical stimulus in the optic nerve and relayed to the brain, which re-creates the image and perceives it.

What is the Tongue Display Unit (TDU)? The TDU is a device that can help transmit visual information via the tongue using electro-tactile signals. The dream of beiong able to restore certain functions of vision via tactile senses is actually a very old one, but one we are only beginning to approach today thanks, in part, to a better understanding of how the brain functions, and also to recent technological adavancements like the miniaturisation of computers and capture devices like web-cams.The first visual-tactile interface system was developed by Dr. Paul Bach-y-Rita in the 1970's. The original tactile visual sensory substitution device (TVSS) was very large (due in part to the large volume of computers and cameras then) and it stimulated the tactile surface of the back to transmit visual information.This system was later adapted by scientist (Kurt Kaczmarek, and Paul Bach-y-Rita) at the University of Wisconsin to use the tactile sense of the tongue to transmit the visual information to the brain.

In Brain, Competing Thoughts Come in Waves and Rhythms Generation Next Blog ← Grown-up fun or girls behaving badly? • Meltdown or tantrum-what’s the difference? → Despite significant advances in brain imaging and cognitive science, neuroscientists continue to search for how the brain develops and retains perceptions and memories. Emerging evidence suggests that a group of neurons can represent each unique piece of information, but no one knows just what these ensembles look like, or how they form. In a new study, researchers at MIT and Boston University gained insight into how neural ensembles form thoughts and support the flexibility to change one’s mind. Researchers identified groups of neurons that encode specific behavioral rules by oscillating in synchrony with each other. “As we talk, thoughts float in and out of our heads. via In Brain, Competing Thoughts Come in Waves and Rhythms | Psych Central News.

Plasticity and The Senses: Paul Bach-y-Rita « Neurons Firing This October 2012 update reflects new links for the videos, as PBS is no longer hosting Wired Science programs. In December 2007 the PBS Wired Science show included a piece about Bach-y-Rita’s research: Mixed Feelings. Here are some additional videos covering some of the same content: BrainPort Vision Through Tongue, BrainPort Balance Device. The first time I heard of Paul Bach-y-Rita was on a public television broadcast of a special show about the brain. The stories of Bach-y-Rita – how his father recovered from a stroke and the impact this had on Bach-y-Rita’s career, the people with severe balancing issues who were essentially cured by his discoveries and innovations, and the people who had no vision who were able to begin to see – are compelling in and of themselves.

World's most detailed scans will reveal how brain works 5 March 2013Last updated at 13:27 ET By Pallab Ghosh Science correspondent, BBC News Continue reading the main story Daydream Believer: an MRI scan of the brain at rest. Regions in yellow are strongly linked to the area indicated by the blue spot. A Little Bit Me: composite of the scans of 20 individuals. A Little Bit You: A comparison of an individual MRI (left) with an average composite from 12 subjects (right). Listen To The Band: yellow and red regions are activated by a task involving listening to stories, whereas green and blue regions are more strongly activated by a task involving arithmetic calculations. It's Nice To Be With You: yellow and red areas are involved in processing social interactions. I Wanna Be Free: a map of the brain's protective sheath, called myelin.

BrainVISA/Anatomist Home Page 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 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. Nerve cells make up the gray surface of the cerebrum which is a little thicker than your thumb.

Historias de nacionalistas vascos. Quien desee conocer la historia del nacionalismo vasco desde dentro, tiene en este libro un testimonio de primera magnitud. Con ello, es evidente que el autor ha tocado un tema tabú, algo que nunca se discute en las tertulias radiofónicas o en los debates de televisión, y apenas en la prensa.

Integral theory Integral theory, a philosophy with origins in the work of Sri Aurobindo and Jean Gebser, and promoted by Ken Wilber, seeks a synthesis of the best of pre-modern, modern, and postmodern reality.[1] It is portrayed as a "theory of everything,"[2] and offers an approach "to draw together an already existing number of separate paradigms into an interrelated network of approaches that are mutually enriching."[1] It has been applied by scholar-practitioners in 35 distinct academic and professional domains as varied as organizational management and art.[1] Methodologies[edit] AQAL, pronounced "ah-qwul," is a widely used framework in Integral Theory. Sri Aurobindo, Jean Gebser, and Ken Wilber, have all made significant theoretical contributions to integral theory. In his book The Ever-Present Origin, Swiss phenomenologist Jean Gebser distinguished between five structures of consciousness: archaic, magic, mythical, mental, and integral. AQAL Theory – Lines.

Quantum mind–body problem An interpretation of quantum mechanics is a set of statements which attempt to explain how quantum mechanics informs our understanding of nature. Although quantum mechanics has held up to rigorous and thorough experimental testing, many of these experiments are open to different interpretations. There exist a number of contending schools of thought, differing over whether quantum mechanics can be understood to be deterministic, which elements of quantum mechanics can be considered "real", and other matters. This question is of special interest to philosophers of physics, as physicists continue to show a strong interest in the subject. History of interpretations[edit] Main quantum mechanics interpreters Although the Copenhagen interpretation was originally most popular, quantum decoherence has gained popularity. Nature of interpretation[edit] More or less, all interpretations of quantum mechanics share two qualities: Two qualities vary among interpretations: Challenges to interpretation[edit]
