Neurogenic radiation is radiation related to a lifeform's brain. It was emitted by a neurogenic stimulator. In 2371, Julian Bashir ordered that Vedek Bareil be given seventy-millivolt doses of neurogenic radiation in an attempt to stimulate brain activity, an amount "five millivolts above what normal tissue can withstand". Unfortunately, this had the unintended side effect of reducing blood flow to his internal organs. Bashir wanted to put him back in stasis to study his condition and preserve him alive, but Bareil opted to remain conscious because his people needed him. (DS9: "Life Support")
