which part of the brain plays a key role in forming and storing the implicit memories created by classical conditioning?
inysia [295]

The part of the brain which plays a key role in forming and storing the implicit memories created by classical conditioning is the Cerebellum.

As well known, the central nervous system (CNS) is made up of the brain and spinal cord. The peripheral nervous system (PNS) on the other hand is composed of spinal nerves that branch from the spinal cord.

The brain is subdivided into 3 parts:

  • The Cerebrum which is the largest part of the brain and is composed of right and left hemispheres and is responsible for performing higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.

  • The Cerebellum which is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance. An additional function of the cerebellum is the formation and storage of memories created by classical conditioning.

  • The Brainstem which acts as a relay means connecting the cerebrum and cerebellum to the spinal cord. It is responsible for many automatic functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing.

Ultimately, The part of the brain which plays a key role in forming and storing the implicit memories created by classical conditioning is the Cerebellum.

nikklg [1K]
The correct answer is A. They are synthesized. 

In the endoplasmic reticulum, proteins are synthesized on to the surface of a rough endoplasmic reticulum. With the help of ribosomes which contains mRNA, the small bounded organelles enter the chamber where mRNA which contains proteins is being released.
