Neuroanatomy Glossary The Papez Circuit Ditki Medical Biological Steps. hippocampus: the dentate gyrus > ca3 > ca1 (via schaffer collaterals) > subiculum. the papez circuit: anatomy. key structures: the parahippocampal gyrus, the entorhinal cortex, the hippocampus, the anterior thalamic nucleus, mammillary nucleus, and the cingulate gyrus and specify the neocortex (external to it). Lies within this bifurcation and communicates with the limbic system (in particular with the mammillary bodies and cingulate gyrus as part of the papez circuit). the medial group nuclei the dorsomedial nucleus connects with the prefrontal cortex.
Neuroanatomy Glossary The Papez Circuit Ditki Medical Biological The role of reticular formation. receives hypothalamic and cortical output and makes connections to other thalamic nuclei and the basal ganglia. provides output to somatic autonomic systems: helps with cardiac, respiratory, bowels, bladder. coordinates brain body response. james papez proposed what structures in the papez circuit. 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 papez circuit, first proposed by james papez in 1937, is a major pathway of the limbic system and is believed to be involved in controlling both memory and emotion (papez 1937; roxo et al. 2011). papez first proposed the idea of a link between the hippocampus, hypothalamus (mammillary bodies), thalamus, cingulate gyrus, and parahippocampal. 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.

James papez, an american neuroscientist who pioneered the study of comparative neuroanatomy, was born in 1883 and died in 1958. he identified a circuit in the mammalian brain which subserves emotional experience and the eponym, papez circuit, is firmly established in the medical vocabulary. papez worked in the secluded laboratory of the cornell. For many, the first encounter with the anterior thalamic nuclei comes from their inclusion within papez circuit for emotion (fig. 1a).this classic theory proposed ‘that the hypothalamus, the anterior thalamic nuclei, the gyrus cinguli, the hippocampus and their interconnections constitute a harmonious mechanism which may elaborate the functions of central emotion’ (papez, 1937).
