Overview of brain chips Introduction Evolution towards implantable brain chips Achievements Benefits of brain chips Drawbacks of brain chips Future of brain chips Conclusion
Introduction It is man that gave technology its presentform but today its entering a phase where itwill out with man in intelligence as we asefficiency. Man has now to find a way in which he cankeep in pace with technology, & one of therecent developments in this regard is the brainchips implants.
Brain chips can enhance memory of human beings, help paralyzed patients and are intended for military purposes. Develop direct interface between brain and computers. Its likely that implantable computer chips acting as sensors may soon assist failing memory, but even provide fluency in a new language…
Evolution towards brain chips … The study of the Brain It is the most complicated area of research. When we enter a discussion on this topic, the works of the physiologist JOSE DELGADO need to be mentioned. Much of the work taking place at the NIH, Stanford is built on the research done in 1950’s by JOSE DELGADO. He implanted electrodes in animal brains and attached them to a "stimoceiver" under the skull…

Studies in human subjects withimplanted electrodes have demonstrated thatelectrical stimulation of the depth of the braincan induce pleasurable manifestations, asevidenced by the spontaneous verbal reports ofpatients, their facial expression and generalbehavior, and their desire to repeat theexperience.
With such experiments, DELGADOunfolded many of the mysteries of the BRAIN,which contributed to the developments in brainimplant technology. For e.g.: he understoodhow the sensation of suffering pain could bereduced by stimulating the frontal lobes of thebrain.
Neural Network Neural networks are loosely modeled on the networks of neurons. They can learn to perform complex tasks. They are especially effective at recognizing patterns, classifying data, and processing noisy signals…
The study of artificial neural networkshas also added to the data required to createbrain chips. They crudely mimic thefundamental properties of the brain. When eventually a network modelwhich resembles the brain in every aspect iscreated, it will be a major breakthrough in theevolution towards implantable brain chips.
Brain cells and silicon chips linked electronically … Researchers working on tiny electrode arrays that links the two. However, once a device is implanted the body develops so-called glial cells, defenses that surround the foreign object and prevent neurons and electrodes from making contact.
Fromherz researches led to thegrowth of three or four neurons on a 180x180transistor array. In few days live nerves…
Achievements In This FieldBrain “pace makers”They are implantable neurons that would perform the functionof a part of brain that has been damaged by stroke orepilepsy...
Retinomorphic chip Retinomorphic chip is a silicon device similar to the human eye, picks out the kinds of features and facial patterns that we use to recognize people and read their emotional state…
Mental mouse Hollow glass cone, size of ball point pen tip. Before implanting, cones are coated with chemicals — taken from tissue inside the patients’ own knees for nerve growth. Implants contain electrode, picks up impulses from the nerve endings. Implants placed in brain’s motor cortex(body movement).
A transmitter inside skull helps the user to pick up signals from the brain and translate them into cursor commands on the computer
Remote controlled Rat Movement signals are transmitted from computer to the brain of rat through a radio receiver strapped to its back. Military purposes and human rescue operations.
Benefits of Brain Chips It will increase the dynamic ranging of senses. Giving light to blind and giving paralyzed patients full mental control of limbs. No genetic modifications in the next generation. Rescue missions(remote controlled rat). The advantage of implants is that they take the decision making power away from the addict. Chips take away ones free will. It enables a person to make a better choice not to take drugs at all.
Drawbacks Cost. Safety(non toxic materials). Losing Identity. Normal range people seen as subnormal. Risk for surgeons.
Future of brain chips It will enhance memory. It might enable “cyberthink”- invisible communication. Enable consistent and constant access to information where and when needed. It will increase the dynamic range of senses, enabling, for example, seeing IR, UV, and chemical spectra.
Conclusion Brain implants enhance capability of human organs and senses. It has a significant role to play in future genetic engineering fields and neuroscience. The implants may enhance your capabilities, but they will expire when you do.
