Biological explanations: neural correlates Flashcards
1
Q
what is meant by neural correlates ?
A
- patterns of structure of activity in the brain that occur with a schizophrenic experience
- putting a person in an fmri when they have an episode and checking which parts of the brain are active or unactive
2
Q
because the patterns of brain activity and a schizophrenic experience occur simultaneously, what can this lead us to believe ?
A
- this could lead us to believe that the patterns observed are implicated in causing schizophrenia
3
Q
what kind of area of the brain is avolition associated with ?
A
- it is associated with the ventral striatum (reward centre)
- which is crucial for anticipation of reward
4
Q
what did Jucke et al do and what did he find ? ?
A
- they measured activity levels in the rewards centre
- found lower levels in schizophrenics compared to control groups
- found negative correlation between activity levels and severity of avolition
- activity levels decrease and avolition increases + vice versa
5
Q
what kind of symptoms also have neural connections ?

- positive symptoms
