Illustrations showing the location of the anterior thalamic nuclei within Papez circuit and the limbic system. ( A ) Schematic drawing of Papez circuit (in black). ( B ) Schematic diagram of the key connections between the anterior thalamic nuclei and laterodorsal thalamic nucleus with sites implicated in Alzheimer’s disease. ATN = anterior thalamic nuclei; HPC/SUB = hippocampal formation, including subiculum; LD = laterodorsal thalamic nucleus; MMB = mammillary bodies; MTT = mammillothalamic tract; PARAHPC = parahippocampal region; PFC = prefrontal cortex; RSC = retrosplenial cortex.
