Could this be Unforgettable?
The film is about a man named David Krane (Liotta), who is obsessed with finding out who murdered his wife.
Later, Dr. Krane goes to a dinner where Dr. Martha Briggs gives a lecture on her experiment to transfer memories via cerebral spinal fluid. After the lecture Dr Krane makes an appointment with Dr. Briggs to go over her research. Dr, Briggs is then approached by an unidentified woman who tells her that Dr. Krane was a suspect in his wife's murder, and if the police department had not botched the investigation he would be on death row.
The following day, at Dr. Briggs office, she goes over the experimental procedure. She states that neuro-peptides are used in forming memories and can be retrieved from Cerebral Spinal Fluid (CSF). However, the peptides themselves are not enough to transfer memories; Therefore, she has created a serum designed to facilitate the memory transfer process. however, the serum is not enough and an external stimulus similar to the memory must also be present for the memories to successfully imprint on the recipient. She gives Dr. Krane a demonstration and they discuss the formula and side effects of the procedure. Dr. Krane suggests using nitroglycerin to alleviate the side effects, but Dr. Brigs mentions that that would only be a short term fix, and the long term complications would still exist. Dr, Krane inquires as to when human trials might start, and she explains she a long way away from that, at least 7 years. Dr. Krane says he would be willing to volunteer to try the serum, and Dr. Briggs responds that not only would it be dangerous, it would be unethical. Dr. Krane apologizes and then leaves.
