In comparison to short-term memory, the storage capacity of long-term memory can last for days, months, years or for an entire lifetime. [6] Long term memory can still be forgotten so the information that is held here is constantly changing over time. [8] Long-term memory has three components.
Research has suggested that long-term memory storage in humans may be maintained by DNA methylation, [35] and the 'prion' gene. [36] [37] Further research investigated the molecular basis for long-term memory. By 2015 it had become clear that long-term memory requires gene transcription activation and de novo protein synthesis. [38]
The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it. [1] A related concept is the strength of memory that refers to the durability that memory traces in the brain. The stronger the memory, the longer period of time that a person is ...
Neither holds information for long, but short-term memory is a simple store, while working memory allows it to be manipulated. [17] Short-term memory is part of working memory, but is not the same thing. Working memory refers to structures and processes used for temporarily storing and manipulating information.
Memory is often thought of as consisting of both a long-term and short-term store. Long-term memory allows us to store information over prolonged periods (days, weeks, years). We do not yet know the practical limit of long-term memory capacity. Short-term memory allows us to store information over short time scales (seconds or minutes).

As we’ve seen, elephants have a large cerebral cortex capable of creating a large long-term memory for their, and the herd’s, survival. Matriarchs build up memories to help the herd survive.
But when should memory problems prompt a person to be screened for dementia? Biden and Trump's age and fitness for the presidency at 81 and 77 years old respectively is a top-of-mind issue for voters.
