Sacks describes Donald, who could not remember killing his girlfriend while under the influence of PCP, but after contusions around the lobe appeared to recover memory for the murder, and two women, Mrs. O'C and Mrs. O'M, with "musical epilepsy" in which the women experienced hearing songs due to pathology in the lobe.

- Frontal; temporal

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).

specific audience will understand the main ideas. for example, if you were writing an instruction manual for rocket scientists, it would likely look very different from one you would write for young children. your language, tone, and writing style would change significantly.
