Brain Implant May Relieve Depression The Telegraph - UK A pacemaker-style implant shown in early trials to relieve the symptoms of severe depression could be available to treat British patients by next year. Deep brain stimulation (DBS), already in use for Parkinson's disease sufferers, is reported to have had immediate and dramatic effects on most of the handful of Canadian patients on whom the technique has been tested. The technique uses electrical pulses, sent via implanted electrodes, to jam neural wiring circuits in a part of the brain linked to depression in patients for whom anti-depressants or electro-convulsive therapy have failed. www.rense.com /general66/brain.htm   (312 words)

Devices that Read Human Thought now Possible: Brain Implants Could Help Severely Disabled CARL T HALL / SF Chronicle ... In the initial behavioral experiments, the researchers recorded and analyzed the output signals from the monkeys' brains as the animals were taught to use a joystick to both position a cursor over a target on a video screen and to grasp the joystick with a specified force. Our analyses of the brain signals showed that the animal learned to assimilate the robot arm into her brain as if it was her own arm." Importantly, said Nicolelis, the experiments included both reaching and grasping movements, but derived from the same sets of electrodes. The brain is continuously learning and adapting, and previous studies have shown that the body representation in the brain is dynamic. www.mindfully.org /Technology/2003/Brain-Implant-Read10nov03.htm   (3647 words)

Moving brain implant seeks out signals - 10 November 2004 - New Scientist Implants could one day help people who are paralysed or unable to communicate because of spinal injury or conditions such as amyotrophic lateral sclerosis (Lou Gehrig’s disease). Electrodes implanted in the brain could, in principle, pick up neural signals and convey them to a prosthetic arm or a computer cursor. Implanted electrodes are usually unable to sense consistent neuronal signals for more than a few months, according to Igor Fineman, a neurosurgeon at the Huntington Hospital, also in Pasadena. www.newscientist.com /article.ns?id=dn6645   (589 words)

Augusta Georgia: technology@ugusta: FDA approves powerful brain implant to help Parkinson's patients 8/4/97 Parkinson's patients' trembling also was eased, but the implant didn't help other symptoms such as the rigidity that also impedes their ability to write and perform other tasks. The implant stimulates one side of the brain to cut tremors on one side of the body. Also, the electrode is powered by a pacemaker-sized ``pulse generator'' that is implanted under the collarbone and must be surgically replaced every three to five years when the battery expires. chronicle.augusta.com /stories/080597/tech_brain.html   (485 words)

Artificial Vision for the Blind - Brain Implant? Bionic Eye? (via CobWeb/3.1 planet03.csc.ncsu.edu)   (Site not responding. Last check: 2007-10-10) A brain implant or cortical implant provides visual input from a camera directly to the brain via electrodes in contact with the visual cortex at the backside of the head. The brain implant on the other hand has the disadvantage that it is invasive, requiring head surgery with a risk of infection, and with many uncertainties about the long-term effects of implanted electrodes. Apart from the brain implant, there is the very promising development of ocular implants, specifically retinal implants for those whose blindness results only from malfunctioning of the retina, e.g., due to retinal degenerative diseases like Retinitis Pigmentosa (RP) or Age-related Macular Degeneration (AMD). www.seeingwithsound.com.cob-web.org:8888 /etumble.htm   (4478 words)

Brain Implants The implants are then placed in the brain’s motor cortex —; which controls body movement — and over the course of the next few months the chemicals encourage nerve cells to grow and attach to the electrodes. Implanting electrodes in rats’ pleasure center of the brain, he attached a device that allowed the rats to activate the electrical impulse. The PABI is based on cochlear implant technology, but extends the utility to stimulating the hearing portions of the brain to restore some degree of hearing function to people deafened by bilateral tumors on their hearing and balance nerves (vestibular schwannomas). www.skewsme.com /implants.html   (5162 words)

World's first brain prosthesis revealed - 12 March 2003 - New Scientist Unlike devices like cochlear implants, which merely stimulate brain activity, this silicon chip implant will perform the same processes as the damaged part of the brain it is replacing. The hippocampus is the most ordered and structured part of the brain, and one of the most studied. It communicates with the brain through two arrays of electrodes, placed on either side of the damaged area. www.newscientist.com /article.ns?id=dn3488   (925 words)

Technology Review: Big Brain Thinking Big Brain Thinking by Guest (John Hatten) 2/14/2006 12:00 AM I think that consciousness emerges from brain activity AND brain activity arises from consciousness. Brain activity being altered will have had an effect on coinscious activity, which subsequently had an adverse effect on brain activity. It may be that shocking a brain will kill a person but a carefully applied stimulus may cause critical activity which could lead to the resumption of conscious thought. www.technologyreview.com /BioTech-Devices/wtr_16325,306,p1.html?PM=GO   (1366 words)

FDA Panel Approves Brain Implant to Control Depression : SF Indymedia   (Site not responding. Last check: 2007-10-10) A surgical implant that stimulates the brain should get government approval to treat chronic depression, an expert panel of federal experts said yesterday -- marking the first time an implanted device has been recommended for the treatment of a psychiatric disorder. Using a technique known as vagus nerve stimulation, the device uses electrodes implanted in the neck to activate brain regions that are believed to regulate mood. The implant involves connecting a wire to the left vagus nerve in the side of the neck; a battery is implanted high in the left chest or under the armpit, and the amount of current can be regulated externally. www.sfimc.net /news/2004/06/1697033.php   (802 words)

Werewolf.com Discussion Boards - FDA Approves Human Brain Implant Devices Three rhesus monkeys were given implants, which were first used to record signals from their motor cortex — an area of the brain that controls movement — as they manipulated a joystick with their hands. The idea is not to stimulate the mind but rather to map neural activity so as to discern when the brain is signaling a desire to make a particular physical movement. Wolpaw said it isn't clear that it's necessary to implant such devices inside the brain; other technologies that monitor activity from outside the skull may prove as effective. www.werewolf.com /vb/showthread.php?t=4952   (843 words)
