Implante cerebral de IA permite ao paciente tetraplégico sentir e mover objetos?

Um homem tetraplégico voltou a sentir e mover objetos por meio de um implante cerebral de IA desenvolvido em 2023.

Keith Thomas ficou paralisado após um acidente e agora controla as mãos de outra pessoa conectada por sensores e eletrodos.

O experimento ligou Thomas a uma mulher com lesão parcial na medula. Ele conseguiu mover e sentir objetos por meio das mãos dela.

O implante usa IA e eletrodos não invasivos para reconectar o cérebro à medula espinhal, criando uma “ponte eletrônica”.

Um ano após o procedimento, Thomas já movia o braço, pegava objetos e sentia texturas, como o pelo de seu cachorro.

Segundo os cientistas, o implante “turbina” o cérebro e os músculos, reconstruindo conexões e devolvendo sensações perdidas.

No novo teste, Thomas pegou garrafas e latas pelas mãos da mulher, distinguindo-as pela textura, mesmo vendado.

O estudo mostra potencial para reabilitar pessoas com lesões medulares e devolver autonomia a pacientes paralisados.
