Interactions between specific regions of the brain

Question 1

Cerebral cortex

Answer 1

2-4mm thick
contains 3/4 of the brain’s neurons
divided into 4 lobes

Question 2

LTM and cerebral cortex

Answer 2

STORAGE OF EXPLIXIT EPISODIC AND SEMANTIC MEMORIES
LT explicit semantic and episodic memories are widely distributed throughout the cortex
permanent storage tends to be in the areas where the relevant information was first processes

Question 3

Hippocampus

Answer 3

3.5cm long, finger sized curve

positioned in the interior of each temporal lobe

Question 4

hippocampus and LTM

Answer 4

CONSOLIDATION OF EXPLICIT EPISODIC AND SEMANTIC MEMORIES AND TRANSFER TO CEREBRAL CORTEX FOR STORAGE
transfers new memories to the cerebral cortex for storage
interacts with the amygdala to form emotional memories - involved in the explicit details of the event
involved in spatial memory - explicit memory for the physical location of objects in space

Question 5

Amygdala

Answer 5

located in the medial temporal lobe

1.5cm long, connected with hippocampus

Question 6

amygdala and LTM

Answer 6

CONSOLIDATION OF IMPLICIT EMOTIONAL MEMORIES
processes and regulates emotional reactions
formation of emotional memory
- classically conditioned fear responses
- consolidation of emotional memories
does not store memories
involved in remembering the emotional significance of an event
encodes and stores implicit memories of simple reflexes acquired through classical conditioning

Question 7

Cerebellum

Answer 7

located at the base of the brain
coordinates fine muscles movements
regulates posture and balance

Question 8

cerebellum and LTM

Answer 8

ENCODING AND TEMPORARY STORAGE OF IMPLICIT PROCEDURAL MEMORIES AND PERMANENT STORAGE OF CONDITIONED SIMPLE MOTOR REFLEXES
involved in activities requiring skilled sequence of movements that require timing and speed
encodes and temporarily stores of implicit procedural memories for voluntary purposeful movements and motor skills
