Can someone tell me the Papez circuit?

Can someone tell me the Papez circuit? I’m getting something in the study material and something different in the notes

Its for the recent memory… The circuit actually starts with the hippocampy–>fornix–> to mammilary body in hypothalamus --> to anterior thalamic nucleus --> via thalamocingulate fibres–> finally to cingulate gyrus

Thank you! After cingulate gyrus how does it go back to hippocampus? That is actually the part i have doubt in. Bcoz it’s given differently in notes and book

Through cingulate gyrus via cingulum to hippocampus. .

It reverberates … I have learnt it from dr. Najeeb … N I think he teaches from snells
