Neuro Pharmacology - Depression and Anxiety

Question 1 of 15

1

Activation of the thalamus can activate the innate fear pathway. Without the collaboration of the prefrontal cortex, this activation can lead to fear manifestations without a source.

Select one of the following:

True
False

Explanation

Question 2 of 15

1

Which of the following statements about the manifestation of anxiety/fear symptoms is not true?

Select one of the following:

Lesions of the medical prefrontal cortex increases the risk for anxiety.
Inhibition of the orbitofrontal cortex leads to the hyperactivity of the amygdala in the presence of a potential threat which produces fear responses.
In the innate fear response, the thalamus is activated by the amygdala with sequential prefrontal cortex activation leading to the fear manifestation.
The amygdala mediates key functions in the processing of fear and threat-related information.

Question 5 of 15

1

Where to benzodiazepines bind and what is their mechanism of action?

Select one of the following:

Question 6 of 15

1

Explanation

Question 9 of 15

1

Drugs binding to α1, α2, α3, α5, and γ subunits of the GABAa synaptic receptor mediate phasic inhibition triggered by peak concentrations of GABA predisposing users to dependence.

Select one of the following:

True
False

Explanation

Question 10 of 15

1

What is the recommended rate of reduction for people wanting to discontinue the use of benzodiazepines?

Select one of the following:

Stop immediately and drink a lot of water
Flumenazil injections over the course of 5-7 days
Decrease by 10 percent each day
None of the above responses are correct

Explanation

Question 11 of 15

1

Barbiturates produce an anti-xiolitic effect by binding to the β subunit of the GABA-a receptor. At high concentrations, they can mimic GABA and directly activate chloride channels.

Select one of the following:

True
False

Explanation

Question 12 of 15

1

Select one of the following:

True
False

Explanation

Question 13 of 15

1

Monoamine Oxidase Inhibitors are Indicated for use with Barbiturates because they shorten the length of action, decreasing side effects.

Select one of the following:

True
False

Explanation

Question 14 of 15

1

Select one of the following:

There is an INCREASE in the amount of BDNF in the Hippocampus and a DECREASE in the amount of BDNF in the Nucleus Accumbens
There is an INCREASE in the amount of BDNF in BOTH the Hippocampus and the Nucleus Accumbens.
There is a DECREASE in the amount of BDNF in BOTH the Hippocampus and the Nucleus Accumbens.
There is a DECREASE in the amount of BDNF in the Hippocampus and an INCREASE in the amount of BDNF in the Nucleus Accumbens.
