Z944 is a T-type calcium channel antagonist with potential applications in pain management. In both epileptic and non-epileptic rats, Z944 disrupts prepulse inhibition. Additionally, it corrects cross-modal sensory and visual recognition memory deficits in Strasbourg genetic absence epilepsy rats. In a neuropathic pain rat model, Z944 restores cortical synchrony and thalamocortical connectivity. In the amygdala kindling model, it delays seizure progression.
