text_A: Nimoy also came up with the concept of the "Vulcan nerve pinch", which he suggested as a replacement for the scripted knock out method of using the butt of his phaser. He wanted a more sophisticated way of rendering a person unconscious. Nimoy explained to the show's director that Spock had, per the story, gone to the Vulcan Institute of Technology and had studied human anatomy. Spock also had the ability to project a unique form of energy through his fingertips. Nimoy explained the idea of putting his hand on his neck and shoulder to Shatner, and they rehearsed it. Nimoy credits Shatner's acting during the "pinch" that sold the idea and made it work on screen.
text_B: After a Vulcan nerve pinch, would a person notice things going on around them?
NO.
