(A) Depiction of the thalamic connections to the medial temporal lobe, modified from Aggleton et al. (2011). (B) Modified figure depicting the key thalamic connections in the present study. Specifically, the anterior thalamic nuclei (ATN) have connections to the hippocampus, and the medial dorsal nucleus (MDN) has connections to the perirhinal cortex. Case NC described here has damage to the MDN. (C) Simplified depiction of connections within the MTL (modified from Murray and Wise 2012). Note that because NC's perirhinal cortex is intact, we hypothesize that object-level representation can still reach the hippocampus, enabling his intact YN recognition memory.
