Answer:
- Frontal; temporal
Step-by-step explanation:
Due to the influence of PCP(Phencyclidine), Donald displays hallucinatory as well as dissociative impacts. Thus, it implies that his memory has been disrupted and he is unable to recall the incident of 'killing his girlfriend' but the contusions surrounding the frontal lobe(which is a significant element of the brain that control human memory, behavior, judgment, etc.) led to recover his memory of the murder. The two women experienced hearing songs and the reason was 'pathology in their temporal lobe'(which is responsible for auditory perceptions).
