stratum oriens (oriens layer)

Introduction

The hippocampus has 4 layers in contrast to the cerebral cortex that has 6.

• stratum oriens (ventricular surface)
  • basal dendrites of pyramidal cells
  • axon collaterals of pyramidal cells
  • incoming axons of the alvear pathway
• stratum pyramidale (pyramidal layer)
  • perikarya of hipocampal pyramidal cells
• stratum radiatum
  • apical dendrites of pyramidal cells
  • recurrent axon collaterals of pyramidal cells
• stratum moleculare et substratum lacunosum (lacunar-molecular layer)
  • distal dendrites
  • incoming axons of the perforant pathway
