Researchers at a neuropsychiatric institute are debating the physiological origins of schizophrenia.
Professor Al-Asadi notes: "Our twin database shows a striking concordance rate for monozygotic twins compared to dizygotic twins, though it never reaches 100%. We also see specific candidate gene clusters."
Dr. Vance responds: "But we must look at the immediate biochemistry and neuroanatomy. Patients exhibiting severe auditory hallucinations show abnormal neural activation patterns on fMRI and altered dopamine activity, while those with severe avolition show structural abnormalities like enlarged ventricles."
Discuss biological explanations for schizophrenia. Refer to the comments of Professor Al-Asadi and Dr. Vance in your answer. ****
Practise AQA A Level Psychology Biological explanations for schizophrenia with exam-style questions for A Level Psychology. 17 questions, matched to the AQA A Level Psychology (7182) specification and written in Paper 1, Paper 2 and Paper 3 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
