Learning and Memory
● Learning
○ Acquisition of knowledge
○ Involves diff skills
○ Knowledge is acquired over time
● Memory
○ Our ability to recall this knowledge
○ Depends on different types of
memories
● Modification of neuronal connections
required for both learning and memory
○ Long lasting changes in synaptic
strength (increase/decrease)
○ Known as synaptic plasticity
■ Underlies all types of
learning
Based on what you have learned in this course:
● Manipulation of which of the following NTs
may help in the treatment of Parkinson’s
disease and control of symptoms ?
A. Glutamate
B. Acetylcholine
C. Dopamine
D. Serotonin / 5HT
E. All of the above
Types of Learning
● Associative learning
○ When 2 stimuli are associated with
e/o (previously unrelated)
○ One stimulus is neutral
● Non-associative Learning
○ A change behaviours after repeated
exposure to a single stimulus
○ Can involve sensitization and
habituation
● Habituation
○ Decrease in response to an
irrelevant stimulus
● Sensitization
○ Avoiding a “harmful” substance
following exposure
○ This is an adaptive survival
mechanism
Has a dish ever made you so sick that you feel ill
every time you think of it or see it served?
● If so you may have more in common with
snails that you thought
● While pond snails were snacking on a
pleasant sugary substance, the authors
exposed snails to an aversive chemical.
● The snails associated the sugary treat with
the unpleasant feeling caused by the paired
chemical and stopped eating it
● The researchers found that the action of very
small proteins related to insulin may
Document Summary
Modification of neuronal connections required for both learning and memory. Based on what you have learned in this course: Manipulation of which of the following nts may help in the treatment of parkinson"s disease and control of symptoms : glutamate, acetylcholine, dopamine, serotonin / 5ht, all of the above. When 2 stimuli are associated with e/o (previously unrelated) A change behaviours after repeated exposure to a single stimulus. Decrease in response to an irrelevant stimulus. If so you may have more in common with snails that you thought. While pond snails were snacking on a pleasant sugary substance, the authors exposed snails to an aversive chemical. The snails associated the sugary treat with the unpleasant feeling caused by the paired chemical and stopped eating it. The researchers found that the action of very small proteins related to insulin may. Lecture 11 stimulate the changes in the brain that take place when such long-term memories are created.
