Forum:Lifeforce harmonizer specific

Lifeforce harmonizer says "when you opponent activates a card effect that inflicts damage, you can discard this card to negate its activation and destroy it." Ok so i have a brain research lab out with 8 psychic counters on it and the opponent uses MST on it. Can i discard my LH to negate that because he is activating a card effect that inflicts damage, even though the card he is using isn't whats inflicting damage. wouldn't it just negate the brain research lab?
