bio electronics - bci, brain computer interface
Bio electronics deals with 'BCI', 'Brain Computer Interfaces'.
Think of what is very popular in press: one man thinks, and that causes the other man to move an arm. Or: a patient wants to speak but is mute, or too ill, and an instrument makes the sound the patient intented to speak out.
As advanced as this may seem, it is in fact a simple side of neuroscience, because all five human senses are dealt with in disctinct parts of the human brain.
Functions as 'memory' or 'sleep' are far more difficult than the expression of an intended movement through a BCI.
Nevertheless: simple results first, and BCI helps a lot of people.
The other way round: if people would like to insert electronics in brains: this is usually forbidden, 'unless life threatening'. Research, and development of applications, is not so much driven by physician's or patient's interests, but by the richest lobby groups. As men are generally richer than women, and elder men certainly richer than younger men, diseases as Parkinson and Alzheimer get a tremendous attention. The whole neurological research agenda is driven by it.
Deep Brain Stimulation in Parkinson is an example of an implant, BCI implanted in the brain.
