Voltage clamp, a Common card
The voltage clamp is a laboratory method used by electrophysiologists and neuroscientists to measure ion currents through the membranes of excitable cells, such as neurons, while holding the membrane voltage at a set level.

Voltage clamp quiz: 3 questions
Three questions on the Voltage clamp card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
This "clamps" the cell membrane at a ______ constant voltage, allowing the voltage clamp to record what currents are delivered.
Answer
desired. This "clamps" the cell membrane at a desired constant voltage, allowing the voltage clamp to record what currents are delivered. From the Voltage clamp article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Voltage clamp. Voltage clamp 69 · Carl Wernicke 65 · Atacama Region 59 · ZFP36 55 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Atacama Region. Atacama Region 17,000 · Carl Wernicke 13,000 · Voltage clamp 9,900 · Method overriding 7,100 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- A basic voltage clamp will measure the membrane potential, and then change the membrane potential to a desired value by adding the necessary current.
- This "clamps" the cell membrane at a desired constant voltage, allowing the voltage clamp to record what currents are delivered.
- Because the currents applied to the cell must be equal to the current going across the cell membrane at the set voltage, the recorded currents indicate how the cell reacts to changes in membrane potential.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Voltage clamp article was read about 9,900 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 69 and blocks with 34: each hit it takes is cut by 14 %.
How to get Voltage clamp
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
