One strength and one weakness of NT as explanation for sz
Good: falkai and Wong
Amphetamines cause dopamine levels to increase and hence dopamine linked
Bad
10 years or more not valid explanation as have no effect
NT as explanation for sz
Sensitivity to d2 receptor so react excessively to dopamine presence. Neurones will depolarise and more signals sent out Mesolimbic is positive and mesocorticol is negative
Genetics as explanation for sz
Higher genetic relatedness more likely to get it e.g mz twins
Genes can be inherited or mutations and lead to neural pathways being damaged in brain and hence behaviours too
Reasons for chi
Independent and nominal
