Neuroleptic shock

Neuroleptic shock was an adverse nervous system condition caused by certain types of energy. The experience of a neuroleptic shock was quite painful.

In early 2373, Kes suffered a severe neuroleptic shock after inadvertantly entering a Nechisti shrine surrounded by a powerful biogenic field. The shock disrupted her synaptic functions, resulting in a state similar to a coma but without the biochemical markers. After undergoing a Nechisti ritual, Captain Kathryn Janeway was able to heal her by taking her back into the shrine. 

When the Srivani infiltrated the USS Voyager in 2374, The Doctor believed that he could neutralize their genetic tags on the crew using a neuroleptic shock. Seven of Nine attempted to modify the ship's EPS relays to generate the shock without alerting the Srivani, but was unsuccessful. 

In 2376, Tuvok entered neuroleptic shock after being struck by a Ba'neth directed energy weapon. The Doctor was able to stabilize him by administering synaptizine, but Tuvok suffered damage to his cognitive, logic, and memory centers.
