Eidetic memory has been reported in children and in patients with synesthesia but is otherwise thought to be a rare phenomenon. Presented herein is a patient with right-sided language dominance, as proven via multiple functional imaging and neuropsychometric methods, who has a seizure onset zone in the right temporo-parietal-occipital cortex. This patient's medically refractory epilepsy and thus hyperactive cortex could possibly contribute to near eidetic ability with paired-associates learning tasks (in both short-term and long-term retention). There are reports of epilepsy negatively affecting memory, but as far as the authors are aware to date, there is limited evidence of any lesion enhancing cognitive functions (whether through direct lesion or via compensatory mechanism) that would be localized to a seizure onset zone in the dominant temporo-parietal-occipital junction.
有报道称，儿童和患有联觉的患者具有遗觉记忆，但除此之外，人们认为这是一种罕见现象。本文介绍了一名患者，经多种功能成像和神经心理测量方法证实，其语言优势在右侧，癫痫发作起始区位于右侧颞顶枕叶皮质。该患者药物难治性癫痫以及因此导致的皮质过度活跃，可能有助于其在配对联想学习任务（短期和长期记忆方面）中具备近乎遗觉的能力。有报道称癫痫会对记忆产生负面影响，但就作者目前所知，几乎没有证据表明有任何病变（无论是通过直接病变还是通过代偿机制）会增强认知功能，且病变定位于优势颞顶枕叶交界处的癫痫发作起始区。
