biological explanations, neural correlates

Question 1

neural correlate

Answer 1

assess the areas of the brain active in a task
positive and negative symptoms have neural correlates
unusual levels of activity in certain areas of the brain of someone with Sz
identified with fMRI scans
ventral striatum is a neural correlate for negative symptoms

Question 2

neural correlates
evidence to support
Juckel et al

Answer 2

compared levels in the brain of Sz to controls
Sz= lower activity in brain areas
negative correlation between ventral striatum and severity of negative symptoms
= activity in ventral striatum is a neural correlate of negative symptoms

Question 3

neural correlates
evidence to support
Allen et al

Answer 3

compared brain scans of Sz with auditory hallucinations and control group
Sz= less activity in superior temporal gyrus and anterior cingulate gyrus
=neural correlate of auditory hallucination

Question 4

neural correlates
limitation
correlational

Answer 4

can’t day if lower activity in one area of the brain causes a symptom
the symptom causes the activity?
a 3rd factor?
