Essay On Brain Computer Interface

2532 Words11 Pages

Abstract- A brain-computer interface (BCI) is a new communication medium between the human brain and a digital world. BCI is emerging technology which can be used at every corner. The ambitious goal of a BCI technology can be the restoration of movements, communication, and environmental control for physically challenged people. An Electroencephalogram (EEG) based brain-computer interface will be connected with a system in order to control home application. It offers an alternative to natural communication and control. It is an artificial system that bypasses the body normal communication pathways. Different brain states are the result of different patterns of neural interaction. These patterns lead to waves characterized by different amplitudes and frequencies. Every interaction between neurons creates a minuscule electrical discharge. This project deals with the signals from the brain, as the different brain states are the result of different …show more content…

BCI gives the details of user’s mental state in the Attention and Meditation level, with the raw signal and information about the brainwave frequencies. The device can be used to interact with home applications. From the past, people are getting more interested in brain and the different activities happening in the brain, Neuroscience research has greatly helped us in our knowledge about the brain activities, and the electrical signals emitted by neurons in the brain. The patterns and frequencies of these electrical signals can be measured by placing a electrodes on different portions of the head. The Brain Computer Interface (BCI) Device measures the analog electrical signals, emitted as brainwaves, and processes them into digital signals. By measuring these different signals we can use them for any different purpose like controlling home appliances of electrical device such as lamps, fans, television

    As particular circuits in our brain strengthen through the repetition of a physical or mental activity, they begin to transform that activity into a habit” (34). Carr establishes his idea of neuroplasticity by providing a test performed by neuroscientist, Michael Merzenich. He observed monkeys with damage to the nerves in their fingers. When a portion of the hurt monkeys’ hands were affected, the indication became disordered because of the way their brains and their fingers were being stimulated. Amazingly, the monkeys adjusted the psychological misperception by their selves.

    I very rarely think in words at all. A thought prevails and I may try to express it in words afterwards, but the words are never there to begin with. But sometimes if I’m lucky, I can identify the thought bubble almost instantaneously with what I like to call “special transmitters”. You see, each thought shape has a different feel – sometimes the thoughts are quiet as a mouse, and sometimes it is loud and thunderous. Sometimes it sounds like it is close by, and sometimes it sounds further off.

    1660 Words  | 7 Pages

    Introduction: Speech is traditionally thought of an exclusively auditory percept. However, when the face of the speaker is visible, information contained primarily in the movement of the lips contributes powerfully to our perception of speech. This combined interaction between auditory and visual modalities improves our ability to interpret speech accurately; particularly in low signal to noise ratio (Bertelson, 2003).This multisensory integration provides a natural and important means for communication. The benefit of integrating audio visual cues has been well documented in normally hearing individuals especially in difficult listening conditions and for listeners with hearing impairment (Sumby& Pollack, 1954).

  • Transcranial Magnetic Stimulation Essay

    3350 Words  | 14 Pages

    Since its introduction, the use of TMS in clinical neurophysiology, neurology, neuroscience, and psychiatry has spread widely, mostly in research applications, but increasingly with clinical aims in mind. Transcranial magnetic stimulation is based on the principle of electromagnetic induction, as discovered by Michael Faraday in 1838. If a pulse of current passing through a coil placed over a person’s head has sufficient strength and short enough duration, rapidly changing magnetic pulses are generated that penetrate scalp and skull to reach the brain with negligible attenuation. These pulses induce a secondary ionic current in the brain. The site of stimulation of a nerve fibre is the point along its length at which sufficient current to cause depolarisation passes through its membrane.

    Accessibility is a concept that essentially applies to the customization of products, services, appliances and environments in a way that enables them to be used by people who have various types of disabilities. Effectively speaking, these products and services are designed in such a manner that enables people with special needs to gain both ‘direct’ as well as ‘indirect’ access to them. At the same time, the benefits of accessibility also extend to a wider category of individuals such as senior citizens and medical patients. Assistive technology is a term that is closely associated with the concept of accessibility. For instance, the application of assistive technology is what makes electronic equipment such as computer screen readers accessible to all categories of end users, including those with disabilities or special needs.
