What is ethanol and why include it? 

Ethanol is drinking alcohol and it often exaggerates the behavioral effects of drugs

What is an anxiogenic environment?

An environment that causes feelings of anxiety and anxiety symptoms.

What is the point in having an observer involved? 

Potentially correcting exaggerated self-scoring, allows for a comparison with how someone felt versus what someone witnessed, etc…

200

What 2 structures receive the densest vCA1 projections and what do they contribute to?

The basal amygdala and lateral hypothalamus. They contribute to anxiety behavior, learned fear and stress responses. 

200

What is the role of the medial prefrontal cortex?

It is a pathway that modulates anxiety related behavior.

300

What type of drug should I not take if I want to learn new information and why? 

Benzodiazepines because they cause anterograde amnesia which doesn’t allow for new information to be learned. 

300

How could the participant pool have played a role in the results? 

The alcohol may not appear to be as significant with majority being men, the excessive cigarette use could have played a role, etc…

300

Why was Ca2+ looked at specifically, what makes Ca2+so important? 

Calcium causes synaptic vesicles to move and fuse with the pre-synaptic membrane and the neurotransmitters can contact the post-synaptic cell. Calcium helps move information.

What was the point of ArchT?

It allowed you to silence vCA1 using light (optogenetic silencing) 

400

(hint:needs a medication that interferes with implicit memory)
