Amnestics, or amnesiacs, are a type of memory-affecting agent that targets memories in a subject's brain once consumed. There are several types of amnestics, with all serving the purpose of erasing problematic memories.

Description[]

Types[]

Class A[]

General Retrograde, or Class A, amnestics are for removing memories of events that have taken place within the last 5-6 hours of the subject consuming the amnestic. They also work well for targeting specific, episodic events that are at the forefront of the mind. These range from traumatic events to simple encounters with the anomalous. Technically, Class A deconsolidates memories at random, though it almost always targets memories that have taken place recently or are unique and/or episodic.[2] A single black stripe signifies Class A amnestic containers.[1]

To maximize effectiveness, during administration, subjects are reminded of the memories that are to be targeted, so that the Class A agent erases them more effectively.[2]

Class B[]

Regressive Retrograde, or Class B, amnestics are for slow, incremental erasure of recent memories. They start with recently formed memories, before working their way backwards until a certain point determined by dosage. A 75 mg dose, on average, forgets events in the past 24 hours. While Class A is best for events occurring within the last 5-6 hours, Class B is best for recent memories that took place longer than 6 hours.[2] A double aqua stripe signifies Class B amnestic containers.[1]

Class C[]

Targeted Retrograde, or Class C, amnestics are for erasing specific memories from any point. These allow for surgically precise removal of any memory, especially being useful for Class-D personnel and humanoid SCPs prior to release. However, the equipment required for Class C amnestics is difficult to transport, necessitating the process to take place at an SCP Foundation facility.[2] A triple bronze stripe signifies Class C amnestic containers.[1]

Administration is typically performed in tandem with high fidelity neuroimaging and transcranial stimulation in an operation. When specific memory engrams are located, the Class C amnestic is activated with ultrasound, magnetic fields, or another non-invasive form of stimulation.[2]

Class D[]

Progressive Retrograde, or Class D, amnestics target early memories, serving as an opposite to Class B amnestics. They're rarely used, as erasing early memories is very seldom needed for containment or to keep staff at high performance. While potent, Class D amnestics require very high dosage for maximum effectiveness. These only expunge explicit memories, while implicit memories (such as skills like speech, walking, and eating) remain.[2] A checkered olive band signifies Class D amnestic containers.[1]

Class E[]

Ennui, or Class E, amnestics serve the purpose of inducing psychological complacency with the anomalous. In layman's terms, Class E amnestics alter the neural pathways to interpret the anomalous as normal. This is typically used in cases where the anomalous cannot be contained or suppressed. In scientific terms, they weaken neural pathways while disassociating the memory with any emotions so that the memories are simply received as ordinary.[2]

Class F[]

Fugue, or Class F, amnestics are for erasing and rebuilding the subject's identity. Class F amnestics induce dissociative amnesia, which allow the subject to forget their identity and either form a new one or be provided one by an amnestics officer with the Medical Department. These are likely used for retiring SCP Foundation personnel or the release of Class-D personnel, though less common than Class C.[2]

Class G[]

Gaslighting, or Class G, amnestics cause subjects to doubt the authenticity of their memories. This amnestic class causes derealization of certain memories, causing one to believe them as occurring in dreams or of a hallucinatory nature. Field Class-G amnestics target anomalous memories, being administered to people that do not have any evidence of an encounter. Class-G amnestics that target non-anomalous memories were initially banned by the Ethics Committee, though are now under development by order of the O5 Council.[2]

Class H[]

Anterograde, or Class H, amnestics prevent the formation of new memories for as long as the agent is within a subject's system. Though this serves a niche purpose, it can be useful for certain situations. An approximate dose of 75 mg lasts for roughly 24 hours.[2]

Class I[]

Transient, or Class I, amnestics induce a temporary amnesic state. This class works by blocking neural pathways for long-term memories, which prevents subjects from recalling their past temporarily. An approximate dose of 75 mg lasts for roughly 24 hours.[2]
