Pregunta 1
Pregunta
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.
Respuesta
- True
- False
Pregunta 2
Pregunta
Which of the following statements about the manifestation of anxiety/fear symptoms is not true?
Respuesta
-
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.

-
It is activated by glutamate
-
It is inhibited by orexin
-
Histamine promotes calm wakefulness through H2 receptors
Pregunta 5
Pregunta
Where to benzodiazepines bind and what is their mechanism of action?
Respuesta
-
They bind to a niche between the α and γ subunits of the GABAa receptors behaving as GABA agonist
-
They bing to the niche between the α and γ subunits of the GABAb receptors acting as a positive allosteric modulator
-
They bind to a niche between the α and γ subunits of the GABAa receptors behaving as positive allosteric modulators
-
They bing to the niche between the α and γ subunits of the GABAb receptors acting as a GABA agonist
Pregunta 6
Pregunta
Positive modulation of the GABAa receptors of the amygdala will produce a hypnotic effect
Respuesta
- True

Pregunta
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.
Respuesta
- True
- False
Pregunta 10
Pregunta
What is the recommended rate of reduction for people wanting to discontinue the use of benzodiazepines?
Respuesta
-

-
Decrease by 10 percent each day
-
None of the above responses are correct
Pregunta 11
Pregunta
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.
Respuesta
- True
- False
Pregunta 12
Pregunta
Overdose of barbiturates can lead to death due to respiratory and cardiac depression and the lack of an effective antagonist.
Respuesta
- True
- False
Pregunta 13
Pregunta
Monoamine Oxidase Inhibitors are Indicated for use with Barbiturates because they shorten the length of action, decreasing side effects.
Respuesta
- True
- False
