Regarding CNNs, feature extraction and classification are integrated into a single structure and optimized automatically. As Jatich concentrated on simple but opposite concepts like up and down, his beta-rhythm EEG output was analysed using software to identify patterns in the noise.
They produce better resolution signals than non-invasive BCIs where the bone tissue of the cranium deflects and deforms signals and have a lower risk of forming scar-tissue in the brain than fully invasive BCIs.
The advantages of such electrodes are: 1 no electrolyte used, 2 no skin preparation, 3 significantly reduced sensor size, and 4 compatibility with EEG monitoring systems. Imagine transmitting signals directly to someone's brain that would allow them to seehear or feel specific sensory inputs.
Recently, successful entrepreneurs such as Elon Musk Neuralink and Bryan Johnson Kernel have announced new startups that seek to enhance human capabilities through brain-computer interfacing. But these electrical, optical, acoustic, magnetic, and genetic BMIs, as crazy as they sound, seem inevitable.
Scientists can detect those signals, interpret what they mean and use them to direct a device of some kind.
Stanford researchers can extract the movement intentions of paralyzed patients from their brain signals, allowing them to use a tablet wirelessly. Phosphenes are spread out across the visual field in what researchers call "the starry-night effect".
A single-array BCI containing 68 electrodes was implanted onto Jerry's visual cortex and succeeded in producing phosphenesthe sensation of seeing light. Choose your preferred classification method, get lots of labeled data, and train your system.
