Brain computer interface
Quantum linked photons can communicate data without an optical path such as a reflection. Beam them into the brain, then modulate their twins to produce microstructured patterns at depth in the brain. | |
There is a system [link] where you can image something
without reflection from the object. Photons strike a
statue
and then their quantum linked pair photon activates a
computer camera. So you could send photons at depth
(say into a body) and image the interior without a
retroreflective
pathway back out through the tissue
New scientist says:
statue<------------- |\|-------------->computer camera
This version
"statue" ------------[\]--------------->shaped energy to brain
So shine this one way light to make images of the brain,
better yet, send a sufficient power of photons to affect
the
neurons in the brain. This should be possible at some
dose, and although the .5b frowns upon genetic
engineering neurons genetically engineered to be
responsive to photons (with opsins) have been created
[link] So you beam light at regular neurons or opsonized
neurons and then Pattern the absorbability with a
custom
"statue" shape thus addressing the neurons (or brain
voxels)
translation: You beam lasers into a brain, and they are
preferentially absorbed where an exterior form shapes
their absorbability. This gives the ability to do brain
stimulation, possibly at depth, without electrodes.

using photons to image mouse brains at neuron level
https://www.ncbi.nl...gov/pubmed/28553965
With a headpiece weighing 2.15 g and a hollow-core photonic crystal fiber delivering 920-nm femtosecond laser pulses, the FHIRM-TPM is capable of imaging commonly used biosensors (GFP and GCaMP6) at high spatiotemporal resolution (0.64 μm laterally and 3.35 μm axially, 40 Hz at 256 × 256 pixels for raster scanning and 10,000 Hz for free-line scanning). We demonstrate the microscope's robustness with hour-long recordings of neuronal activities at the level of spines in mice experiencing vigorous body movements. [beanangel, Jan 10 2018]

Not Y.A.W.N. ! Yet Another Waste of Net-space

I don't know enough about synaptic activity to tell whether this would work or not, but it did remind me of an 1980's imagining of a brain-machine interface from the Clint Eastwood film, Firefox that featured a brain-reading Mig that responded to Russian-language'd thoughts. [link] |

There is another version of this where the quantum linked
photons are emitted by a satellite than scan the surface of
the earth and a space based camera looks at the images, all
without an optical return path. It is used to see through
clouds. It might just be a design rather than a built though. |
|
| |
If this works, perhaps it could also be used to allow communication between the brain and the mouth? |

//You beam lasers into a brain,// |
|
| |
You beam lasers a few hundred microns into the surface of
the brain. |
|
| |
Clearly, then, you need a much more big laser. |

gigawatt should be enough. I mean, granted, it's power is
only so mighty because it's energy is delivered in
femtosecond pulses, but you can't argue with the headline
figures. |
|

The published imaging is better than I thought. At a
wearable device they can see green fluorescent protein in
the neurons of mice at 3.35 micrometer resolution where
they look at spines on the neurons. [link] |
|

The little mice are able to roam about wearing a scanner
headset; "We demonstrate the microscope's robustness
with hour-long recordings of neuronal activities at the
level of spines in mice experiencing vigorous body
movements" |
|
| |
so engineer the human brain to make color coded neurons
(GFP etc) then locate particular neurons spatially then a
femtosecond later use that location information to send a
bunch of form (statue) shaped quantum linked photons to
the same location, apparently down to the neuron. |
|
| |
Now this neuron spine level imaging on moving mice
(*presumably* with intact skulls) is very favorable, but
another search result says the spatial resolution is 1.6 to
4 millimeters. |

I think therefore ion. Quite proud of that one - dances
around room waving large inflatable centipede toy in
triumph. As for the idea..... yawns.....zzzzzzzz. Wakes up
to idea of a sink full of pink dishwater comtaining dozens of
gray cups and saucers. |
|
| |
"Idea" may be a bit of an overstatement there. |
|

Just to improve things a little, I read the hemoglobin is the
main absorber of photons. That suggests that replacing the
blood with a fluorocarbon could improve the optical
resolution. I think this is fairly harmless at rodents and
might be at people, at least for a little while. |

How did they pivot from that to a web browser? |
|
| |
Subjective encoding might still be a sticking point. |

Of course he doesn't, he was far too young, and Tatooine was a long way from all the action. |

[voice] Optogenetics is an area of active research. |
|

The link says " optogenetics, a recently developed technology that can be used to control the activity of genetically-defined neurons with light. Cells are first genetically engineered to express a light-sensitive opsin, which is typically an ion channel, pump, or G protein–coupled receptor. When engineered cells are then illuminated with light of the correct frequency, opsin-bound retinal undergoes a conformational change that leads to channel opening or pump activation, cell depolarization or hyperpolarization, and neural activation or silencing" |
