THE DIFFERENT SECTIONS OF THE BRAIN:
If the left side of your brain is more developed like most people's are, you are right handed. On the other hand if the right side of your brain is more developed, then you will be left handed. The right side of your brain is more artistic and emotional while the left side of your brain is your common sense and practical side, such as figuring out math and logic problems.
One of the most important parts of the human brain is the cerebellum. The cerebellum is involved with the more complex functions of the brain and sometimes is even referred to as the brain within the brain. The cerebellum acts as a control and coordination center for movement. The cerebellum carries small programs that have been previously learned. For example, how to write, move, run and jump are all previously learned activities that the brain recorded and can playback when needed. Every time you practice, the brain rewrites the program and makes it better. You may have heard the saying practice makes perfect. Well this saying is not entirely true; another way of practicing is just to imagine what you wish to do. Since the cerebellum can't actually feel, it will think that you are doing what your imagining and respond by rewriting it's previous program and carrying out any other actions needed for that function.
THE CEREBRAL CORTEX:
The cerebral cortex makes up the top of the two hemispheres of the brain. The cortex is a sheet of greyish matter which produces our thoughts, language and plans. It also controls our sensations and voluntary movements, stores our memories and gives us the ability to imagine, in short it's what makes humans, humans.
Measures are needed to stop brain scans being misused by courts, insurers and employers, experts have warned. At least one US company is offering scans to employers recruiting staff.
"After data mining and online profiling, brain imaging could well become the next frontier in the privacy wars.
"The promise to read a person's mind is beguiling, and some applications will be greatly beneficial.
"But a combination of exaggerated claims by commercial providers, inadequate legal regulation and the persuasive power of images bring very real dangers for us as citizens."
A wireless headset that can interpret brain waves to control video games and other onscreen action, had been shown off at a hi-tech conference. The Emotiv Epoc claims to be the first neural headset aimed at consumers. The system, which is already on sale, uses a century old medical technique to read electrical signals in the brain. The technology then uses a series of algorithms to convert them into onscreen movement.
The implications of such 'brain manipulation' is fascinating! On the other hand don't expect me to run over to You Tube to play guinea pig, not yet at least. (My brains subjected to enough on ATS - I don't need to go digital!) So for now, please, any of you out there who've 'tried' the 'digital high'? Give up some personal experience information. Tell us if there's any 'validity' to these claims. Can these digital 'highs' be harmful? Beneficial? If so - how?
An increasing number of neural implantable devices will become available in the near future due to advances in neural engineering. This discipline holds the potential to improve many patients' lives dramatically by offering improved—and in some cases entirely new—forms of rehabilitation for conditions ranging from missing limbs to degenerative cognitive diseases. The use of standard engineering practices, medical trials, and neuroethical evaluations during the design process can create systems that are safe and that follow ethical guidelines; unfortunately, none of these disciplines currently ensure that neural devices are robust against adversarial entities trying to exploit these devices to alter, block, or eavesdrop on neural signals. The authors define “neurosecurity”—a version of computer science security principles and methods applied to neural engineering—and discuss why neurosecurity should be a critical consideration in the design of future neural devices.
A 2007 WHO report indicated that neurological disorders—such as injury, spina bifida, stroke, encephalitis, multiple sclerosis, Parkinson disease, and Alzheimer disease—affect up to 1 billion people worldwide.21 Unlike traditional approaches that stress accommodation of the needs of the neurologically affected via drug interventions or intrusive and costly home or hospital care, neural engineering combines cutting-edge technologies to develop a proactive role in understanding more about how the nervous system works, in order to provide rapid, complete, and effective treatment, rehabilitation, and assistance. These technologies can allow patients to experience more freedom and independence in their daily lives than ever before.
Computer security and privacy is a field within computer science dedicated to the design and engineering of technologies so that they behave as intended, even in the presence of malicious third parties who seek to compromise the operations of the device. These malicious parties are often called hackers, attackers, or adversaries. Three of the standard goals in computer security are confidentiality, integrity, and availability: an attacker should not be able to exploit the properties of a device to learn private information (confidentiality); an attacker should not be able to change device settings or initiate unauthorized operations (integrity); and an attacker should not be able to disable a device altogether and render it ineffective (availability). We define neurosecurity as the protection of the confidentiality, integrity, and availability of neural devices from malicious parties with the goal of preserving the safety of a person's neural mechanisms, neural computation, and free will.
We base our argument on several facts. First, security vulnerabilities have already been found in implanted medical devices. In our past research, we experimentally demonstrated that a hacker could wirelessly compromise the security and privacy of a representative implantable medical device: an implantable cardiac defibrillator introduced into the US market in 2003. Specifically, our prior research found that a third party, using his or her own homemade and low-cost equipment, could wirelessly change a patient's therapies, disable therapies altogether, and induce ventricular fibrillation (a potentially fatal heart rhythm).10 Although we only conducted our experiments using short-range, 10-cm wireless communications, and although we believe that the risk of an attack on a patient today is very low, the implications are clear: unless appropriate safeguards are in place, a hacker could compromise the security and privacy of a medical implant and cause serious physical harm to a patient.
We believe that some future hackers—if given the opportunity—will have no qualms in targeting neural devices. We have already seen examples of malcontents and vandals using computers in an attempt to cause physical harm to patients: in both November 2007 and March 2008 individuals placed flashing animations on epilepsy support websites, causing some patients with photosensitive epilepsy to experience seizures.9,17 In the context of a neural device, there is an added risk that these vandals can take advantage of neural plasticity to make longer-term alterations to a person's neural computation. There have also been cases of illegal self-prescription in which patients tried to use their own implantable medical devices to cause themselves harm.1 Patients with neural devices may self-prescribe in an attempt to enhance their performance, increase their level of pain relief, or overstimulate the reward centers in the brain.
Michael Mosely's new BBC Four series explores the controversial history of researching the mind. Here are five of the most ethically dubious brain experiments, as featured on the show.

Researchers are developing artificial limbs, wheelchairs and computers which can be controlled by the user's thoughts.
Thought-controlled wheelchairs and nerve-controlled prosthetic arms are some of the latest innovations in bionics being discussed at a science conference in Washington. The wheelchair can be directed by brain signals detected using a cap fitted to the user and is the work of scientists at the Ecole Polytechnique Federale de Lausanne in Switzerland (EPFL). It is part of efforts to control machines directly via brain signals, which could lead to new devices for the paralysed and disabled.
