Neuro-synaptic field
From Memory Alpha, the free Star Trek reference.
A neuro-synaptic field is an artifical form of energy which lowers the emotional barrier of an individual.
In 2154 Commander Shran captured Soval to interrogate him. Soval was directly beamed into an interrogation chair on board the Kumari where he was tortured. The machine created a neuro-synaptic field which lowered the emotional threshold of Soval and made him open for emotional pain. (ENT: "Kir'Shara")
