Regarding the specific case you mentioned, I don't have access to real-time information or details about individual legal cases or testimonies. I don't have any specific information about a neurologist testifying for the prosecution in the Pittsburgh synagogue shooting case.
In general, the role of mental illness in criminal cases can be complex and highly debated. It is essential to rely on objective and evidence-based expert opinions from qualified professionals to assess the influence of mental health conditions in such situations.
Mental health experts can provide valuable insights into a defendant's mental state and whether mental illness may have played a role in their actions. However, determining the impact of mental illness on criminal behavior requires careful evaluation and consideration of multiple factors, including the individual's psychiatric history, their mental state at the time of the incident, and any potential mitigating circumstances.
It is crucial to remember that each case is unique, and legal proceedings should follow a fair and thorough examination of all available evidence and expert testimonies to reach a just and unbiased decision.
