Cognitive neuroscience memory

Question 1

Long-term potentiation

Answer 1

Long term potentiation (LTP) occurs when a neuron shows an increased excitability over time due to the repeated synaptic input. The hippocampus uses long term potentiation during classical conditioning.

Question 2

Habituation

Answer 2

Habituation occurs when an individual ceases to respond to a stimuli after a prolonged period of time, if the stimulus is not associated with any reward or punishment.

Question 3

Sensitisation

Answer 3

Sensitisation is the strengthening of a response to a stimulus due to the response to a secondary stimulus. Sensitization: For example, if a loud sound is suddenly heard, an individual may startle at that sound. If a shock is given following the sound, then the next time the sound occurs, the individual will subsequently react stronger to the sound.
