Papez Circuit Medicine Studies Medicine Student Physiology The purpose of this review is to assess the anatomy of the limbic structures and to elaborate on the anatomical connectivity of the limbic circuits as an update to the original papez circuit. please be advised that investigating possible functions of the limbic structures is beyond the scope and intent of this review. The papez circuit refers to an anatomical circuit in the brain that plays a crucial role in memory and emotion. it involves several central nervous system nuclei and pathways, including the cingulate cortex and the hippocampus, which are important for memory function. lesions along this circuit can disrupt memory, with the specific deficit.
Neuroanatomy The Papez Circuit Perforant Pathway Ditki Medical The papez circuit, first proposed by james papez in 1937, is a circuit believed to control memory and emotions, composed of the cingulate cortex, entorhinal cortex, parahippocampal gyrus, hippocampus, hypothalamus, and thalamus. pursuant to james papez, paul yakovlev and paul maclean incorporated th …. The region of the brain believed to be responsible for these activities formed a physical border between the hypothalamus and the cerebrum. therefore, it was called the limbic system; arising from the latin word limbus, meaning edge. the limbic system is considered to be the epicentre of emotional and behavioral expression. Hippocampal physiology: the papez circuit & perforant pathwaythe papez circuit: overview papez circuit physiology • it is the fundamental extra hippocampal circuitry, which papez introduced in 1937. • originally believed to play a fundamental role in emotional processing regulation but is now understood to be the cornerstone of memory processing consolidation, instead.steps the entorhinal. The papez circuit involves various structures of the brain. it begins and ends with the hippocampus (or the hippocampal formation). fiber dissection indicates that the average size of the circuit is 350 millimeters. the papez circuit goes through the following neural pathways: hippocampal formation (subiculum) → fornix → mammillary bodies.

The cingulate cortex projects back to the entorhinal cortex of parahippocampal gyrus, completing a “great” loop called the papez circuit. the papez circuit like many other areas of the limbic system is involved in learning and memory, emotion, and social behavior, and was originally thought (by james papez) to the anatomical substrate of. Expanded the papez circuit to include the prefrontal cor tex, septum, and amygdalae as part of the limbic system. this model has been accepted and almost unchanged ever since (maclean 1949, 1952). mb = mammillary bodies. fig. 1 a 3 d reconstruction of the major gray and white matter struc tures of the limbic system including the papez circuit.
