has it clear. Your way to know the most hidden corners of our head is already underway. How do you want to do it?
All this could be crucial for the amount of data we are handling right now.
While there are advances in our ability to read or write information in the brain, these are usually based on brain implants, which allows doctors to control diseases such as epilepsy.
However, surgery is too risky to justify such interfaces in healthy people and current external monitoring approaches such as electroencephalography (EEG).
In which the electrodes are directly connected to the scalp, are too inaccurate.
As such, DARPA is trying to stimulate an advance in the minimally invasive brain-computer (BCI).
To achieve this, Robinson’s team plans to use modified viruses (called viral vectors) that will send genetic material to cells to insert DNA into specific neurons and produce two types of proteins.
The first type absorbs light when a neuron is firing, which makes it possible to detect neuronal activity.
An external headset would send a beam of infrared light that could pass through the skull and into the brain.
The ultimate goal of the US is to create thought-controlled weapons like drones that can send or transmit images from one brain to another
The detectors connected to the headset would measure the small signal that would be reflected in brain tissue to create an image of our brain.
For this protein, the selected areas appear darker when the neurons are activated, generating a reading of the activity that can be used to determine what the person is seeing, hearing or trying to do.
The second protein depends on the magnetic nanoparticles, so the neurons can be stimulated to trigger when the headset generates a magnetic field.
This could be used to stimulate them in order to induce an image or sound in the patient’s mind.
As a test, the group plans to use this system to transmit snapshots from one person’s visual cortex to another.
