The ethical arguments about memory dampening may include:

A. While complete memory erasure is still an element of science-fiction, certain neurological drugs have been proven to dampen the strength & emotional association of a memory.
B. Propranolol, an FDA-approved drug, has been suggested to effectively dull the painful effects of traumatic memories if taken within 6 hours after the event occurs. This has begun the discussion of ethical implications, assuming the technology for memory erasure will only improve. Originally, propranolol was reserved for hypertension patients. However, doctors are permitted to use the drug for off-label purposes—leading to the question of whether they actually should.
C. There are numerous reasons for skepticism; for one, it may prevent us from coming to terms with traumatic experiences, it may tamper with our identities & lead us to an artificial sense of happiness, demean the genuineness of human life, and/or encourage some to forget memories they are morally obligated to keep.
D. Whether or not it is ethical to fully or partially erase the memory of a patient, it is certainly becoming a more relevant topic as this technology improves in our society.

Some bioethicist believe that neurological treatments may alter "brain identity".

A. Neuroscience has led to a deeper understanding of the chemical imbalances present in a disordered brain. In turn, this has resulted in the creation of new treatments & medications to treat these disorders. When these new treatments are first being tested, the experiments prompt ethical questions.
B. First, because the treatment is affecting the brain, the side effects can be unique & sometimes severe. A special kind of side effect that many subjects have claimed to experience in neurological treatment tests is changes in "personal identity".
C. Although this is a difficult ethical dilemma because there are no clear & undisputed definitions of personality, self, and identity, neurological treatments can result in patients losing parts of "themselves" such as memories or moods.
D. Yet another ethical dispute in neurological treatment research is the choice of patients. From a perspective of justice, priority should be given to those who are most seriously impaired and who will benefit most from the intervention. However, in a test group, scientists must select patients to secure a favorable risk-benefit ratio. Setting priority becomes more difficult when a patient's chance to benefit and the seriousness of their impairment do not go together.

What is the developing history of brain–computer interface (BCI)?

A. Professor Phillip Kennedy built the first intracortical brain–computer interface by implanting neurotrophic-cone electrodes into monkeys in 1987. After conducting initial studies in rats during the 1990s, Professor Miguel Nicolelis at Duke University developed BCIs that decoded brain activity in owl monkeys & used the devices to reproduce monkey movements in robotic arms. Following years of animal experimentation, the first neuroprosthetic devices implanted in humans appeared in the mid-1990s.
B. In 1999, researchers led by Yang Dan at the University of California, Berkeley decoded neuronal firings to reproduce images seen by cats. In 2009, the NCTU Brain-Computer-Interface-headband was reported. In 2011, researchers reported a cellular based BCI with the capability of taking EEG data & converting it into a command to cause the phone to ring.
C. In 2015, the BCI Society was officially launched.
D. In 2017, Neurostyle launched the first commercially available BCI system called Neurostyle Brain Exercise Therapy Towards Enhance Recovery (NBETTER) for stroke rehabilitation. It comprises a system that detects motor imagery with virtual reality feedback mechanism & optional additional physical feedback using a Continuous Passive Movement device.
