Slightly Odd Question For A Sci Fi Novel
For context, I'm writing a sci fi novel in which one of the sources of conflict is a frequency (or combination of frequencies, technically) that affect the human brain in such a way as to provoke certain emotions at will, as a form of mind-control.
My question is this: Is there such thing as, or would there be reason to create, a neural-network-like computer that is physically structured similarly enough to a human brain to be affected in a similar way by external frequencies? For example, could neurons in the ANN be physically separated and communicate through electrical signals similarly to actual brain synapses? Could an external frequency then cause interference between the neurons that might have a similar effect? Since the computer obviously couldn't have induced emotions, I'm imagining an effect more like confusion, tasks being interrupted, the wrong data going to the wrong places, etc. The device in question would be a drone using the neural network for adaptive navigation, object avoidance, adapting to environmental changes like wind, etc. so the impact would be something like it steering off course and struggling to read and transmit data.
Sorry I know this is not a very scientific question but I'm trying to make my book grounded in reality wherever possible, even if the sci fi elements are of course taking some creative liberties.
I'm a computer engineering student, but know very little about ANNs aside from the general concept (I might take a course about them next year but so far I haven't had any). Pointing this out to say you don't necessarily need to explain in complete layman's terms, particularly general computer concepts, but I may not understand all ANN-specific terminology.
