A 22-year-old man reported seeing scenes from his family’s pizzeria as well as his local train station, all while sitting in a medical room. Researchers hope the discovery could help them better understand areas of the brain used to retrieve information on locations. The black dots represent the probes researchers used to cause a hallucination in their patient. Dr Mégevand at the Feinstein Institute in New York first scanned the volunteer's brain using functional MRI while he looked at images of different objects and scenes. Activity from the implanted electrodes was then recorded as the patient looked at a similar set of pictures The black dots represent the probes researchers used to cause a hallucination in their patient.

Now scientists are one step closer to such technology after forging a new brain monitoring technique that could lead to the development of 'mind-reading' applications. The breakthrough comes from a Stanford University School of Medicine study that was able to 'eavesdrop' on a person's brain activity as they performed normal functions by utilizing a series of electrodes attached to certain portions of the brain. The process, called 'intracranial recording', was tested on three epilepsy seizure patients who had been admitted to the hospital for pre-surgery observation, according to FoxNews.com. They also found that activity in this brain region spiked several other times throughout the day. By watching back video recordings of the experiments, the research team discovered that whenever a number was mentioned - even just through words like 'many' or 'more than' - the same spikes were seen in the intraperietal sulcus, which was a very unexpected finding. The team found that an area of the cortex around the hippocampus was activated when the subject looked at images of places. ‘There are these little spots of tissues that seem to care about houses and places more than any other class of object,’ team member Ashesh Mehta at the Feinstein Institute told the New Scientist. The implanted electrodes were used to stimulate the brain in this area which triggered a series of visual hallucinations. The young man initially described seeing a familiar railway station and later a part of his home, but no smells or sounds were associated with the scenes. When stimulation of these brain areas was repeated, the same hallucinations occurred. And when the researchers stimulated electrodes in a slightly different area, in the inferior temporal gyrus (ITG), the volunteer said that faces suddenly became distorted. ‘Maybe a specific group of neurons encodes a memory of a person wearing an apron, another group encodes an oven or a street, and when you stimulate them altogether it evokes a familiar memory of that place where all those things were,’ said Dr Mehta. Dr Mehta said the experiments may eventually help people who who suffer from conditions such as autism or Alzheimer's disease. The research follows a study at Stanford University, which two years ago revealed that electrodes placed another area in the brain were vital in a person’s ability to process faces.

An induced procedure to have you recall a certain incident, then digitally reproduce it, then it becomes evidence to jail you. Very useful to identify persons who do not like what the government is doing, so they can be dealt with (Removed or isolated from society). It would be a good idea to pay more attention to current events.+20-2 Jack Sprat, London,... This happened to both myself and a Buddhist monk from whom I took non-stop vipassana (insight) instruction. We each went back, during trance, to childhood days. When it happens, you experience all sensory experiences that were present at that time with perfect clarity. I was suddenly transported back to when I was ten years old, and could read what was written by one of my brothers on the wall at home, which included childhood words which I had completely forgotten about. Nothing is lost, and I believe that it is all cracked open, like a spool of film, during the death state also, As de Quincey remarked in 1806, from his opium use, 'the dread book of account is nothing less than the contents of one's own mind'. Quite so. God is not mocked, and there's no escaping yourself, or what you've done, either..+17-` overandout, nowhereland...this has been done under hypnosis, without any massive electrode use, for years+2-6 Daemon666, Southampton, United Kingdom That is voluntary memory recovery. We are talking here about possibly being able to help people who are unable to recover a memory because they are unable to stimulate the right brain area. Hypnosis allows people to do what they can already do but might have difficulty with if they are not relaxed. This breakthrough might help people with structural brain issues.+6-2 Post Comment Private Reply Ignore Thread
