In terms of its sub-regional differentiation. the hippocampal CA1 region receives cortical information directly via the perforant (temporoammonic) path (pp-CA1 synapse) and indirectly via the tri-synaptic pathway where the last relay station is the Schaffer collateral-CA1 synapse (Sc-CA1 synapse). Research to date on pp-CA1 synapses has been conducted predominantly in vitro and never ... https://www.roneverhart.com/Western-Digital-Ultrastar-DC-HC530-WUH721414ALE6L1-0F31170-14TB-7-2K-RPM-SATA-6Gb-s-512e-SED-3-5in-Hard-Drive/
