Neuralyzer
The Neuralyzer is technology that features in Men in Black.

History
The Neuralyzer was a device used by the Men in Black to alter the memories of any non-MiB who encounter alien activity on Earth. The Neuralyzer was a core piece of technology utilized by the Men in Black to maintain the secrecy of extraterrestrial life on Earth by erasing or altering the memories of civilian witnesses. Developed through reverse-engineering of alien technology recovered from off-world incidents, the Neuralyzer represented the culmination of multiple alien cognitive manipulation techniques condensed into a sleek, portable Earth-compatible device. The earliest Neuralyzers were believed to have been produced during the formative years of the Men in Black organization in the mid-20th century, initially large and unstable until refined by MIB scientists in conjunction with cooperative alien advisors. By the late 1990s, the device had reached a high degree of miniaturization and reliability, becoming standard-issue gear for all field agents. Used routinely after close encounters, alien sightings, or unauthorized breaches of protocol, the Neuralyzer ensured that humans retained no memory of extraterrestrial contact, preserving the illusion of normalcy and global stability.
Overview
In appearance, the Neuralyzer was a small, cylindrical device roughly the length of a thick marker or cigar, composed of polished chrome or stainless alloy housing with a smooth, reflective surface. The top portion of the cylinder featured a sliding panel or pop-up mechanism which, when triggered, revealed a bright red or blue xenon light tube. Along the side were a series of tiny dials, micro-switches, and digital readouts used by the agent to input the time frame of the memory erasure—from a few minutes to several years. The device included a safety interlock that prevented accidental discharge and a built-in ocular shield for agents to protect themselves from its effects. When activated, the Neuralyzer emitted a brief pulse of high-intensity light directly into the subject’s visual cortex, temporarily stunning and rewriting neural pathways associated with short- and long-term memory.
At its most basic level, the Neuralyzer functioned as a neurological suppression and reprogramming device, designed to selectively wipe memories from a human brain. It disrupted the electrochemical activity of targeted memory centers within the hippocampus and prefrontal cortex, effectively removing specific recollections while leaving the rest of the mind intact. After administering a Neuralyzer flash, MIB agents would provide replacement memories through verbal suggestion—filling in blanks with plausible explanations like gas leaks, hallucinations, weather phenomena, or sleepwalking. This allowed the agency to contain incidents without raising public suspicion or initiating large-scale panic. While the Neuralyzer was one of the Men in Black’s most vital tools in preserving interstellar secrecy, its ethical use required careful calibration and restraint, as excessive exposure could result in long-term psychological damage or cognitive gaps.
The neuralyzer activates by flashing a burst of energy into the target's eyes, erasing a specific amount of time from their memory- as little as a few minutes, or a retiring MiB agent's entire career. The target then becomes extremely suggestible, giving a MiB agent the option to describe a new set of memories to them. The only way to avoid the neuralyzer's effects is by wearing MiB-issue sunglasses. The neuralyzer's alterations can be reversed with a de-neuralyzer, but such devices are extremely rare.
