Parietal Lobe and Memory Functions

What are the two components of the dual-process model of episodic memory?

Recollection and familiarity

Which brain region shows enhanced activity for successful recollection?

Hippocampus

What brain region's activity decreases with familiarity, suggesting a role in familiarity-based recognition?

Perirhinal cortex
