Improving brain-machine interface performance by decoding intended future movements*



 
PARASOL PICTURES is proud to be part of the Proxy Cybernetic Interior Intention Program and looks forward to using and understanding and analyzing the effect of straight to cortex narrative and the influence of an extended Brain Computer Interface a subject that  cannot control either the input or output of content.
Sound and Vision  introduced straight to cortex  exerts a powerful influence on human thoughts, emotions, memories, and behavior, and can be particularly important when A.I. is used to deter  a human organism .

 Because few are aware of the precision of our objectives to develop and perfect  Direct Neural Interface the target subject for this important research  presents as mental illness. For the sake of unregulated research and development the lack of public awareness serves "The Greater Good" well in this misunderstanding and provides basis and incentive for The Parasol Pictures new A.I. teams to not be fettered by public opinion nor provincial conditions concerning Mind Research.

Thanks to nanotechnology sensing particles  that can enter a human organism without the subject's approval which could  hinder a  researcher's need  to understand how synthetic telepathy might be understood a human organism un ware of the logistics of the technology as something alien or supernatural . This lack of  awareness of mind /machine interface serves as a level   playing field for creating a wide range of occult and eclectic narrative upon  a wide variety "of types" to understand and  improve basic understanding of narrative effects pertaining to thresholds concerning psychological threshold and sanity. Biosensors  which attach to neural tissue in the subject allow for interactive real time Tele-Presence based upon real time  brain activity associated with narrative influence . Although Parasol Pictures has been asked to structure most of it's Imbue Technique  as punitive eventually Parasol Pictures because of it's cooperation with agencies outside of the private sector   will be able to parlay models of straight to cortex narrative influence not only upon dissidents and potential threats to national security but to a wide demographic of participants as to best  understand the effect of both the traditional media and the relatively new medium of Intra cortical Interface as it concerns  group behavior ,gaming  and entertainment .
 
 
 ..... one goal of the  Interior Intention Program is to create Brain Computer Interface  technologies that remove the screen  between screenwriter ,actor  and consumer, allowing  the future consumer 's neural responses to entirely drive  the story's trajectory. In this way, moment-by-moment neural activity establishes plotlines and psycho -cybernetic  story outcome attenuated toward the future consumer's  neural signatures that are simultaneously  cognitive  and emotional . Enhanced perception and instigated experience we at Parasol Pictures expect will be an exciting ride for both Mentor and Mentee in ways that traditional television and cinema could not.

 

 

Breakthrough for electrode implants in the brain

Summary:
For nearly nine years, researchers at Lund University have been working on developing implantable electrodes that can capture signals from single neurons in the brain over a long period of time - without causing brain tissue damage. They are now one big step closer to reaching this goal, and the results are published in the scientific journal Frontiers in Neuroscience.
 

 
The Lund researchers' tailored electrodes, which they call 3-D electrodes, are unique in that they are extremely soft and flexible in all three dimensions, in a way that enables stable recordings from the neurons over a long time.
 

For nearly nine years, researchers at Lund University have been working on developing implantable electrodes that can capture signals from single neurons in the brain over a long period of time -- without causing brain tissue damage. They are now one big step closer to reaching this goal, and the results are published in the scientific journal Frontiers in Neuroscience.
This technology would make it possible to understand brain function in both healthy and diseased individuals.
"There are several elements that must go hand in hand for us to be able to record neuronal signals from the brain with decisive results. First, the electrode must be bio-friendly, that is, we have to be confident that it does not cause any significant damage to the brain tissue. Second, the electrode must be flexible in relation to the brain tissue. Remember that the brain floats in fluid inside the skull and moves around when we, for instance, breathe or turn our heads.
The electrode and the implantation technology that we have now developed have these properties, which is unique," says Professor Jens Schouenborg who together with Dr Lina Pettersson led the project.
The Lund researchers' tailored electrodes, which they call 3-D electrodes, are unique in that they are extremely soft and flexible in all three dimensions, in a way that enables stable recordings from the neurons over a long time.
The electrode is so soft that it deflects against a water surface. In order to implant such electrodes, the researchers have developed a technique for encapsulating the electrodes in a hard but dissolvable gelatine material that is also very gentle on the brain.
"This technology retains the electrodes in their original form inside the brain and can monitor what happens inside virtually undisturbed and normally functioning brain tissue," says Johan Agorelius, a doctoral student in the project.
Until now, developed flexible electrodes have not been able to maintain their shape when implanted, which is why they have been fixated on a solid chip that limits their flexibility, among other things. Other types of electrodes that are used are much stiffer. The result in both cases is that they rub against and irritate the brain tissue, and the nerve cells around the electrodes die.
"The signals then become misleading or completely non-existent. Our new technology enables us to implant as flexible electrodes as we want, and retain the exact shape of the electrode within the brain," says Johan Agorelius.
"This creates entirely new conditions for our understanding of what happens inside the brain and for the development of more effective treatments for diseases such as Parkinson's disease and chronic pain conditions than can be achieved using today's techniques," concludes Jens Schouenborg.
Facts about the electrodes
The electrodes are made of 4 mm gold leads and individually insulated with 4 mm parylene. The array of electrodes consists of eight flexible channels, designed to follow the movement of the brain.
Both the electrode and implantation technology, which have been tested on rats, are patented by NRC researchers, in Europe and the US, among other places.

Abstract

OBJECTIVE:

A brain-machine interface (BMI) records neural signals in real time from a subject's brain, interprets them as motor commands, and reroutes them to a device such as a robotic arm, so as to restore lost motor function. Our objective here is to improve BMI performance by minimizing the deleterious effects of delay in the BMI control loop. We mitigate the effects of delay by decoding the subject's
