The part of the brain most involved in creating implicit memories (like habits and motor skills) is the basal ganglia , along with strong support from the cerebellum.

Key brain region

  • The basal ganglia (especially the striatum) are central for forming procedural memories and habits, such as learning to ride a bike or type without looking at the keys.
  • These structures help link repeated actions and feedback into automatic, unconscious routines, which is exactly what implicit memory is.

Supporting structures

  • The cerebellum is crucial for motor learning and classical conditioning (like conditioned blink responses), another core form of implicit memory.
  • Other regions (like parts of the neocortex and amygdala) contribute to specific implicit processes such as priming and emotional conditioning, but they are not considered the main hub in basic textbook-style questions.

How this fits exam-style wording

  • When a multiple-choice or psych textbook asks, “Which part of the brain is most involved in creating implicit memories?”, the expected answer is basal ganglia (sometimes phrased as “cerebellum and basal ganglia,” with basal ganglia emphasized for habit/procedural learning).

TL;DR: The best single answer: basal ganglia.
