Associative Fear Leaning Is Thought to Occur Through LTP at Cortico-Amygdala

question 45

Multiple Choice

Associative fear leaning is thought to occur through LTP at cortico-amygdala synaptic connections. To further study the involvement of synaptic plasticity in memory, experiments have used optogenetic stimulation of post synaptic neurons at the time of tone delivery and this results in

• A) formation of an artificial fear memory without the need for a foot shock.
• B) erasure of a fear memory
• C) erasure of an olfactory triggered memory
• D) inability for synapses of cortico-amygdala axons to induce LTP
• E) inability for synapses of cortico-amygdala axons to induce LTD.
