<unk>  is the selective artificial removal of memories or associations from the mind.<unk>  has been shown to be possible in some experimental conditions; some of the techniques currently being investigated are: drug-induced amnesia, selective memory suppression, destruction of neurons, interruption of memory, reconsolidation, and the disruption of specific molecular mechanisms. There are many reasons that research is being done on the selective removal of memories. Potential patients for this research include patients suffering from psychiatric disorders such as post traumatic stress disorder, or substance use disorder, among others.<unk>  is also featured in numerous works of fiction, with fictional methods and properties that do not necessarily correspond with scientific reality.
