Since the writer has pointed out "te surgical interventions are done", that is, the surgery is finished, so to say without surgery" is confusing.
Context:
Alternatively a
http://en.wikipedia.org/wiki/Brain%E2%80%93computer_interface can be used connecting the subject to his own body. A study
[1] using a monkey as a subject shows that it is possible to directly use commands from the brain, bypass the spinal cord and enable hand function. An advantage is that this interface can be adjusted
after the surgical interventions are done where nerves can not be reconnected without surgery.Also, for the procedure to be practical, the age of the donated body must be sufficient: an adult brain cannot fit into a skull that has not reached its full growth, which occurs at age 9–12 years.
There is an advantage, however, with respect to the immune response. The brain is an
