Memory

Question 1

Describe the different types of memory

Answer 1

Memory can be split into working-memory (pre-frontal cortex) and long-term memory.

Question 2

Describe the different forms of long-term memory and which structures affect them?

Answer 2

Long term memory can be explicit or implicit.
Explicit = EPOSODIC (autobiographical events, remembering day-to-day things, eg appointments) or SEMANTIC (knowledge about something, eg lion)

Implicit
= skills/habits (cerebellum, basal ganglia)
= conditioned reflexes (cerebellum and others)
= emotional (amgdala)

Question 3

What is the hippocampus’ role within memory?

Answer 3

-forming new memories (anterograde amnesia)

Question 4

What is the role of the hypothalamus

Answer 4

-drive related behaviour
-food, sex, thirst,
-collection of nuceli
(septum nuceli = addiction)
controls the thyroid

Question 5

What is the role of the mammillary bodies within memory?

Answer 5

-encode new memories

damage = no sense of passing time, no new memories

Question 6

What is the role of the amygdala?

Answer 6

• fear/pleasure centre
• receives highly processed info
• important in emotional memory
• inhibition

Question 7

What is the role of the cingulate gyrus?

Answer 7

• motivation

- damage = apathetic

Question 8

What is the Neuroendocrine Function of the Hypothalamus?

Answer 8

1. Posterior Pituitary
   neuroendocrine system = oxytocin (love hormone) and ADH

2. Anterior pituitary 
Portal vein system
 Prolactin = milk
 LH/FSH = gonads
 TSH = thyroid 
ACTH = adrenal
GH = growth

Question 9

What structures are in the limbic system?

Answer 9

• Hippocampus
• Hypothalamus
• Amygdala
• Cingulate gyrus
• mammillary glands (encoding memories, passing time, new memories)
• fornix
