A brain zap is common withdrawal symptom of certain anti-depression and anti-anxiety drugs. A seemingly electrical pulse is felt to rush across the brain. Not painful but momentarily disorienting. A brain zap is usually not unpleasant and may be followed by a few seconds of slightly dizzy or even euphoric feeling.
When ever I watch DVDs on my cheap player, the movie always seems to have a little pause or brain zap right in the middle.

The large biomechanical brain from the metroid games. It was featured as a boss in 3 of the games. The mother brain is a giant brain in a glass case that acted as a giant computer for the space pirate forces. It bears one large eye capable of launching energy attacks and has indestructable gun turrets protecting it. The mother brain gets its energy from long columns of nerves in her chamber called zebetites. In Metroid for NES, Samus had to destroy zebetite barriers to get to the mother brain. In super metroid for the SNES, The mother brain had a huge bio-mechanical body built for the sole perpous of killing samus. In this form it had a hyper eye beam, and was able to spew projectiles at samus.
