The PMHNP is explaining to her patient the role of 5HT in depression, specifically the "Behavioral Inhibition" system. What is the best explanation of this system below?
Respuesta
-
It is linked to pleasure and reward, and this becomes overactive in depression, decreasing inhibition.
-
It is linked to the stimulus of the PFC, and subsequently behavioral arousal
-
It is tuned to responding to fear or anxiety producing stimuli

NE is a monoamine, specifically a [blank_start]catecholamine[blank_end].
Respuesta
-

-
nucleus
-
locus
-
ceruleus
Pregunta 16

Respuesta
-
NE stimulates the NA, then the PFC and then the VTA
-
NE stiumulates the PFC, then the VTA and then the NA
-
NE stimulates the VTA, then the PFC and then the NA
-
