This page covers biological details of component group Rhinal Cortex. Component group is part of aHuman target integrated biological model.

• Top-down path to center: Cerebral Cortex -> Parahippocampal Lobe (NC.LOBE.PH) -> Anterior Parahippocampal Gyrus (FMM.NC.PHA) -> Rhinal Cortex (NC.PHA.RH) (see Mind Maps)
• Function: Memory consolidation and olfaction perception

Components

(generated)

Component items:

• Entorhinal Cortex (FMM.NC.PH.ET): Memory consolidation
  • Lateral Entorhinal Cortex (FMM.NC.PH.LEC): Memory consolidation, emotional aspects
  • Medial Entorhinal Cortex (FMM.NC.PH.MEC): Memory consolidation, basic, view independent position
• Perirhinal Cortex (FMM.NC.PH.PER): Associate different visual views of objects and their various nonvisual attributes
• Piriform Cortex (NSA.NC.PH.PIR): Perception of smells, primary olfactory cortex
• Prepyriform Cortex (NSA.NC.PH.PRP): Perception of smells, relay via MD to PFC
