The term Medial Temporal Lobe is a misnomer for the combination of hippocampal formation ( HPF ) and posterior parahippocampal gyrus (PPG). It is a functionally defined concept of the anatomical substrate for declarative memory (conscious memory for facts and events) ( Squire-2004 ). In most related literature, the HPF and PPG are considered as separate structural and functional units. The HPF is composed of archicortex and the PPG of neocortex ( Economo-1927 ). Functionally, the PPG is involved in processing stimulus object information transmitted via temporal lobe pathways; The part of the HPF involved in declarative, or episodic memory processing, the anterior parahippocampal gyrus, processes stimulus context information transmitted through the parietal cortex and retrosplenial cortex ( Aminoff-2023 ).
