Era seu nó cortical . A cortical inhibitor (não é a mesma coisa) é um dispositivo médico que suprime a atividade mental da onda teta para prevenir certos tipos de danos telepáticos.
O episódio ao qual você está se referindo é VOY: " Erro humano ".
EMH: Is it that obvious? I've completed my diagnostic. What you experienced was no malfunction. Your cortical node was designed to shut down your higher brain functions when you achieve a certain level of emotional stimulation.
SEVEN: Clarify.
EMH: It appears to be a fail-safe mechanism to deactivate drones who start to regain their emotions. Knowing the Borg, it makes perfect sense. Finding one's heart is the surest road to individuality.
Brannon Braga teve o que dizer sobre o assunto:
"It was my feeling that Seven Of Nine should have died. If you watch the episode ‘Human Error’ written by Andre Bormanis, it was not only a heart breaking episode in that Seven Of Nine learns, as she begins to explore her human emotions, that she can’t experience them. There’s a Borg chip inside her that will kill her if she tries to do so. First of all, that’s kind of an interesting ‘rape victim’ analogy or whatever you want to call it, about a damaged woman who can’t get past what happened to her, but I also always saw it as a crucial episode that would set up the finale.
"This was a woman who knew she was neither here nor there. She couldn’t go back to the Borg, nor would she want to, but she could never be fully human, so she was doomed. And I wanted to have her sacrifice herself to get her shipmates home."
