[Verse 1] Deep within the temporal lobe's embrace Lives a formation with computing grace Not just hippocampus as some might say But entorhinal cortex leads the way Through dentate gyrus, CA fields align Three-two-one, then subicular design A circuit mostly flowing one direction Save CA3's recursive reflection [Chorus] Two axes guide us through this neural maze Septotemporal runs through all our days Dorsal spatial, ventral feels the stress Proximodistal sorts the input mess Medial lateral streams know where to go Feedforward current with one recursive flow [Verse 2] From septal dorsal down to temporal zone In rodent brains this gradient's clearly shown But flip it round in human architecture Posterior to anterior, the stricture Dorsal thinks in maps and spatial schemes While ventral drowns in amygdala dreams HPA axis pulls the emotional strings As gene expression gradients spread their wings [Chorus] Two axes guide us through this neural maze Septotemporal runs through all our days Dorsal spatial, ventral feels the stress Proximodistal sorts the input mess Medial lateral streams know where to go Feedforward current with one recursive flow [Bridge] Proximal CA1 receives a different stream Than proximal CA3, it's not what it seems Entorhinal cortex splits its pathways clean Medial and lateral, a topographic scene Each band of tissue knows its destined place Along the transverse axis, keeping pace [Verse 3] Dentate gyrus marks the starting line For proximodistal's grand design CA fields stretch out like piano keys Each zone receiving what it needs Subicular complex completes the chain Before the signals loop again Remember hippocampal formation's wide Not just CA fields, but the whole divide [Verse 4] Theta rhythms pulse through septal side While gamma oscillations coincide Sharp wave ripples during quiet rest Replay memories and consolidate the best Place cells fire when location's right Grid cells pattern space so bright Time cells count the moments as they flow While border cells define where we can go [Final Chorus] Two axes guide us through this neural maze Septotemporal runs through all our days Dorsal spatial, ventral feels the stress Proximodistal sorts the input mess Medial lateral streams know where to go Feedforward current with one recursive flow Formation's bigger than proper alone EC to subiculum, claim your throne
