Abstract

The piriform cortex (PC) plays a pivotal role in the onset and propagation of temporal lobe epilepsy (TLE), making it a potential target for therapeutic interventions. This review delves into the anatomy and epileptogenic connections of the PC, highlighting its significance in seizure initiation and resistance to pharmacological treatments. Despite its importance, the PC remains underexplored in surgical approaches for TLE. We examine the specific neuroanatomy of the PC as well as the limitations of current imaging techniques and surgical interventions, emphasizing the need for improved imaging protocols to safely target the PC, especially in minimally invasive procedures. Furthermore, the PC’s proximity to vital structures, such as the lenticulostriate arteries, presents challenges that must be addressed in future research. By developing multimodal imaging techniques and refining surgical strategies, the PC could emerge as a crucial node in improving seizure freedom outcomes for TLE patients.
