Brain-computer interface (BCI) is a collaborative arrangement between an equipment and a brain that channelizes signals from the brain to command some external operation, like controlling a prosthetic limb or a cursor. The interface facilitates a direct communication pathway between the object to be controlled and the brain. In the case of cursor control, for instance, the signal is carried directly from the brain to the mechanism instructing the cursor, rather than considering the normal route via the body's neuromuscular framework from the brain through the finger to the mouse. By decoding signals from a gamut of neurons and employing computer programs and chips to convert the signals into action, BCI can allow a person suffering from disability to control a motorized wheelchair or write a book or do tasks with prosthetic limb through the integration of thoughts alone. The present brain-interface devices need deliberate well planned thinking to make some future applications, like prosthetic control, are estimated to work seamlessly. However, the BCI technology comes with a range of challenges. One of them is to develop electrode equipment and/or surgical techniques that are minimally invasive. The conventional BCI model enables the brain to accept an implanted mechanical device and administers the equipment as a natural process of its presentation of the body. The modern research is prone to emphasize more on the capabilities of non-invasive BCI.

Good and Bad Side of BCI


Although we already understand the basic principles behind BCIs, it’s necessary to know the advancements and drawbacks pertaining to the integration of BCI. Let’s focus on the plus points first. The neural signals are constantly focusing on creating technology to restore speech for disabled individuals. An implant in a part of the brain linked with speech (Broca's area) would emit signals to a computer and subsequently to a speaker. Proper training would help the subject to think each of the 39 phonemes present within the English language and make them speak through speaker linked with the computer. NASA has come up with a similar framework, although it reads electric signals from the nerves in the throat and mouth area, rather than reading them from the brain directly. They succeeded in conducting a web search by "typing" the term "NASA" mentally into Google. Cyberkinetics Neurotechnology Systems is endorsing the BrainGate, a neural interface framework that enables the paralyzed individual to administer robotic prosthesis, computer cursor or a wheelchair.


The Japanese researchers have found a basic Brain Computer Interface Market that enables the user to handle their avatar in the online world. On the other hand, the brain is an incredibly complicated system. The actions or thoughts taking place inside the brain are the outcomes of simple electric signals, would be an absolute understatement. There are almost 100 billion neurons functioning within a human brain. Neurons are constantly receiving and sending signals by means of a complex web of network. Chemical reactions are also involved in the process which are not to be ignored. Those reactions are hard to read for the electroencephalogram (EEG). The signal in EEG is weak and have chances of interference. EEGs gauge the smallest voltage capacities. Something as insignificant as the blinking eyelids of the user can create much stronger signals. Refinements in implants and EEGs are estimated to win over this issue to some extent in the future, but presently, decoding brain signals is similar to listening to a congested phone network due to the presence of a large amount of static. In addition to the aforementioned drawbacks, the lack of portability of the device is also considered a major flaw of BCI.


Conclusion


The brain computer interface market is attaining new heights with the constant progression in technology. BCI has proved to be a boon for mankind, especially for the disabled or paralyzed. The innovations in the healthcare sector is helping the global BCI market size to mushroom at exponential rates. Despite having some significant flaws, Brain Computer Interface is considered as one of the best inventions of the era.
