-Perceptual distortions include being distressed by hallucinatory voices; seeing visions;
reporting hallucinations of touch, taste, or odor; or reporting that familiar things and

grins or giggles; peculiar repetitive gestures; talking, muttering, or mumbling to oneself;
or glancing around as if hearing voices.

grandiose expansiveness. often occurs in schizophrenia and in many drug-induced
psychoses

Grandiose expansiveness - Correct Ans-exhibiting an attitude of superiority; hearing

have a psychotic component - Correct Ans-psychosis

-social conditioning

-alogia
-anhedonia
-amotivation
-asociality

area of the brain thought to be responsible for the positive symptoms of schizophrenia is
the ____________. one of the neuronal pathways known to be affected here is the
___________ from the _____________ and the _____________. - Correct Ans-limbic
system, mesolimbic pathway, ventral tegmental area (VTA), nucleus accumbens

schizophrenia: the dopamine theory - Correct Ans-suggests that in the mesolimbic
pathway, neurons from the VTA (ventral tegmental area) release higher than normal
levels of dopamine into the synaptic cleft at the NAC (nucleus accumbens).
-More dopamine binds to the D2 dopamine receptors in the NAC. This is thought to be
the cause of positive symptoms

Schizophrenia: dopamine and mesocortical system - Correct Ans-area of the brain
thought to be responsible for negative symptoms of schizophrenia, prefrontal cortex
-mesocortical pathway goes from the VTA (ventral tegmental area) to the PFC
(prefrontal cortex)
-dysregulation of dopamine between these two areas of the brain results in the negative
and cognitive symptoms

schizophrenia: dopamine release at PFC - Correct Ans-dopamine theory suggests that
in the mesocortical pathway, neurons from the VTA (ventral tegmental area) release
lower than normal levels of dopamine into the synaptic cleft in the PFC (prefrontal
cortex).
-Less dopamine binds to the D1 dopamine receptors in the PFC.
-cause of the negative and cognitive symptoms

Dopamine pathway: mesolimbic - Correct Ans-location: Ventral tegmental area (VTA)
within midbreain to the nucleus accumbens (NA) in the limbic system
