As of recent times, rats have communicated through wireless brain implants, from across the globe. Also, recent fMRI technologies have allowed prediction of movements (or intention), and the visualization of brain waves (or 'seeing' your thoughts, images, etc.)
Rats have been used for testing, and some advances allowed scientists to predict intention, induce and/or subdue emotions and thoughts.
Reading or controlling the mind requires modifying/reading neural oscillations on neurons, and doing so on certain parts of the brain. Since the neural oscillations are the base of thought and cognition itself, how can we fight our own oscillations? This question stems from the possibility of mind control/reading in humans.
If the technology directly modifies our thoughts.. how can we fight that very structure? In science fiction, people "fight" against implants and control, but in reality, is that even possible? Can we fight our own oscillations?
For example, your mind is being read for a thought that you consciously know, like a password, and can you fight this attack? Another example, your mind is being controlled, you are being coerced, and since neural oscillations are thought itself, you can't have objections.
Can we have objections?
Can we fight our neural oscillations if they are hijacked?
