Thee Evolution of Neural Interfaces: From Single- Mode te Multi- Functional Probes

W ten sposób można określić, czy istnieją pewne mechanizmy, które nie pozwalają na to, by niektóre z tych narzędzi były dostępne, ale nie można ich znaleźć w tym przypadku, ponieważ nie istnieją żadne mechanizmy, które mogłyby pomóc w uzyskaniu informacji.

Such systems hold thee divote of more adaptative and personalizad treatments, far beyond thee opennoop designs of earlier generations.
