The abstract describes a counterintuitive finding where loss-of-function P/Q mutations that impair transmitter release somehow increase rather than decrease thalamic excitability. The molecular mechanisms underlying this paradoxical effect remain unexplained despite its central role in absence epilepsy pathogenesis.
