Emotions are a poorly understood aspect of both brain function and body chemistry. Most likely they are tirggered in the Limbic region of the brain and function through the use of hormones and other chemcical messangers. If we assume that brain function and hormonal triggers can be altered by manipulating brain waves via a neuralprocessor these effects too must be possible.
Neurochemical Induction: Pathological Fear
This is another possible affect of adrenalin overdose. A simple subliminal message and a healthy dose of adrenalin can have a punk climbing the walls, terrified but not sure what of. For all intents and purposes cool checks are all going to fail, though a modifier may be more fair to players. Though if this punk get's cornered watch out.
Neurochemical Induction: Sleep
There's another pair of hormones in the body that play a role in sleeping. Melatonin and seratonin. By stimulating the brain and affecting the secretion of these hormones it is possible to make a target drowsy or fall asleep outright. I'd recommend a skill check like in combat against the program using the target's willpower/coolness.
Neurochemical Induction: Depression
Serotonin also affects the target's emotional states, namely their ability to be cheerful. Too much seratonin can result in increasing levels of depression. This is of course a very hard affect to inflict on players so I'd recommend its use on NPC's.
Neurochemical Induction: Rage
Hormones play a role in almost all the emotional states, from fear and arousal to outright anger and rage. While in this case the hormones may not directly trigger the emotion they do play a role in preparing thebody to act in accordance with that emotion, and that can set up a feedback loop.
Neurochemical Induction: Lust
There are several versions of this program. Some trigger lust for any member of the opposite sex. Some trigger homesexual feelings, others can set the target of lust as a specific target. The effects can range from inducing fantasies in that person, to driving them to great lengths to achieve their new found goals.
