which of the following statements highlights the relationship between dopamine and schizophrenia?
dopamine fails to produce any pleasurable effects that heighten the sensory experience of a patient suffering from schizophrenia.
people with schizophrenia may have more receptor sites for dopamine in an area of the brain that is involved in emotional responding.
schizophrenia manifests as a result of an imbalance in dopamine levels between two adjoining neurons with conflicting electrical charges.
underutilization of dopamine by the brain is connected with hallucinations and disturbances of thoughts and emotions.

Explanation:

The dopamine - hypothesis of schizophrenia suggests that people with schizophrenia may have an over - activity of the dopamine system, often manifested as having more dopamine receptor sites in certain brain areas involved in emotional responding. Option 1 is incorrect as dopamine can still have effects in schizophrenia patients. Option 3 is not a well - established view on the relationship. Option 4 is wrong because overutilization rather than underutilization is more commonly associated with symptoms like hallucinations in the context of dopamine and schizophrenia.

Answer:

People with schizophrenia may have more receptor sites for dopamine in an area of the brain that is involved in emotional responding.
