CA3 #
- Probably the most significant. Divided further into CA3a, b, and c.
- Rich in pyramidal neurons.
- Has cholinergically driven Theta rhythms which is key in the hippocampus for memory formation, with LTP occuring primarily during the positive phase of the theta rhythm, the strength increasing linearly with its amplitude.
- Slow scalp EEG Theta waves correlated with memory retrieval, fast negatively correlated. Distinct slow and fast cortical theta dynamics in episodic memory retrieval
