Abstract
The thalamus is a densely connected collection of nuclei that play a critical role in gating information flow across the neocortex. Through diffuse reciprocal cortico-thalamo-cortical connectivity, the anterior and centromedian nuclei exert remarkable control over cortically expressed activity. Consequently, mounting evidence implicates these thalamic centres in both the genesis and propagation of aberrant epileptiform activity across the brain. The present work reviews existing literature with regards to the anatomy, function, and dysfunction of the anterior and centromedian thalamic nuclei as they relate to epileptogenesis and ictal dynamics in humans. A confluence of electrophysiological, anatomical, and neuromodulatory evidence links these thalamic hubs to a variety of epilepsy syndromes. These data are discussed as they relate to targeted thalamic neuromodulation.
