Brain-Computer Interface Enables Wireless Communication.
Cognitive systems are increasingly being used to assist in the ability to control many of our daily activities, and there has been an increasing interest in developing a method to interface with the body to give an electrical signal to the brain. The technology used to give this electrical signal is called Brain-Computer Interface. This paper describes two methods for developing such a system; a wireless interface and a neuromorphic interface. The wireless method is the one in use for the Brain-Computer Interface System developed at the University of Colorado at Boulder, but the neuromorphic interface is presently being used in some commercial devices. The goal of this paper is to give an overview of both technologies. The methods are discussed in terms of how they involve either human subjects or robots, and at the end of this paper there is a summary of the problems to be solved in both methods as well as some suggestions for future work.
The ability to communicate with the brain has become a key element in a number of modern systems. For example, neuromorphic technologies use electronics to mimic brain functions. The key technology used is at the core of Brain-Computer Interface. The methods described here enable a wireless interface between an electronic system and the brain. The potential uses range from remote control to cognitive assistive devices to assist in the ability to interact with the world around us.
The first method to communicate with the brain is the interface which involves a human subject. A wide variety of ways are being investigated to enable the use of a brain-computer interface in the future. The interface proposed here is based on research carried out at the University of Colorado Boulder (Carver, 2009).
The brain is the most complex and diverse system in the body. A complete understanding of the brain is therefore not likely to be achieved through a series of experiments. It is the goal of human-robot interfaces to enable communication between a human brain user and a robot. There have been a number of studies designed to develop brain-computer interfaces (Carver, 2006). The first demonstration of a brain-computer interface was carried out by the MIT group.
Brain-computer interfaces for neural recording and stimulation
Description: Computers & Intelligence: The brain is the most powerful computer ever built. It is an amazing computing machine, the brain of a living being. Now it can be used to interface with other living beings and to record and manipulate their behaviors.  The first implantable brain-computer interface device was created in the early 1990s, but it was not until 1999 that the first ever practical application of the technology was published. This article describes the development of this interface and provides first-hand experience with the operation and usability of a prototype implant.
I have a confession to make. It is a confession that I could not possibly make without the aid of a little technical assistance.
Today you will find the first ever brain-computer interface (BCI) device, developed by Prof. Peter Pons, working on the brain of a real person in the laboratory of the Department of Brain Research at the Massachusetts Institute of Technology (MIT). The subject of this article is Dr. David Eagleman’s (MIT) ongoing series of experiments with BCIs.
Brain-computer interface (BCI) is currently the most promising technology that has been invented for the human brain. In fact, its use is already being extended to other kinds of animals, including monkeys.
If the results of Eagleman and colleagues are accurate, this might have a huge impact on human society and the way we live. We may soon be able to manipulate, control, and train the brain of a human. It is not too much of a stretch to imagine that this power can be used for the benefit of patients suffering from chronic neurological disorders or even for the benefit of those who suffer from schizophrenia or neurological disorders of unknown origin. The prospect of a brain interface will most likely mean a completely new way of thinking about these diseases. For example, we might be able to cure them and they could be rendered more responsive to drugs. Similarly, they will be able to control and record their own behaviors in a way analogous to that of a person who has gone blind or who has been locked in an artificial body.
This is only possible if the technology can be developed that is safe, accurate, and has a long time of use.
Neurograins: wirelessly networked and powered electrophysiological neural microchips
Scalable connectivity configuration of 48 neurograins for recording neural activity.
Neuromorphic hardware consists of transistors, microchips and silicon chips with on-chip digital circuits running computer software in programmable logic gates. Today, this hardware technology is used to emulate biological cell assemblies, especially neurons, and to build neural circuits. Neuromorphic hardware combines analog electronic components with programmable logic gates, which enables complex networks of electronic analog electronic circuits to be built. Neurograins are neuromorphic hardware assemblies with arrays of neural circuits that are formed from arrays of connected neuromorphic units. They are connected by neuromorphic circuits and are operated by an array of programmable logic cells. The hardware designs that are used today are based on silicon circuit technology and use logic functions such as addition, AND, OR, XOR, AND, OR, NOT, AND, OR and NOT gates for neuromorphic circuitry. An important type of neuromorphic is the neuromorphic array, where each neuromorphic circuit is a row in the array, and each neuromorphic logic unit is a column in the array. To create neuromorphic arrays, an array of neuromorphic logic units is assembled. The resulting array contains an array of neuromorphic circuit blocks connected by neuromorphic wiring. The connection between the neuromorphic logic units of each circuit block is designed using a neuromorphic interconnect technology, and this interconnect technology is built around neuromorphic logic functions such as AND, OR, XOR, AND, AND, OR, NOT and NOT gates.
Neuromorphic hardware is used to simulate biological neural circuits and circuits to build neural networks. It has been used to build neuromorphic hardware based upon the design for neuromorphic engineering (Denk and Tsai, 2008). In the past, neuromorphic hardware circuits have been modeled using Boolean logic circuits. Boolean circuits are binary circuits that consist of a combination of one bit for each Boolean function that is used in neural computation. Examples of the Boolean circuits can be found in books such as (Barthel, 2010). The Boolean logic circuits are designed using Boolean function and Boolean gates. But it is possible to build complex Boolean circuits using neuromorphic circuits (e. , Denk and Tsai, 2008).
Tips of the Day in Computer Networking
A VLAN is a special type of network connection, called “virtual LAN,” that allows multiple hosts to share the same physical network connections. They are created with help of the iptables rule: an iptables rule that allows traffic to be blocked, except when specifically permitted. The following two lines should be set into the file `/etc/sysctl.
The above will allow traffic coming in from any host connected to the same switch, but will block traffic originating from any host that has set up its iptables rule to permit traffic.
Note: Netstart/stop vlans on the host will enable VLAN filtering, but if this is turned on on a host connected to a different switch, it will be unaware that traffic is being blocked (i. the switch would be unaffected).
