title: H-channels in epilepsy: new targets for seizure control?
abstract: Hyperpolarization-activated cation channels (h-channels) are key regulators of neuronal excitation and inhibition, and have a rich diversity of subunit composition, distribution, modulation and function. Recent results indicate that the behavior of h-channels can be altered significantly by seizures. The activity-dependent, short-term and long-term plasticity of h-channels can, in turn, modulate neuronal excitability. The reciprocal interactions between neuronal activity and h-channels indicate that these ion channels could be promising novel targets for anti-epileptic therapies.
