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 ...
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]
In order to form a memory, there needs to be a strong activation of the neurons, and then there needs to be a plasticity effect—meaning, there needs to be some kind of little change in the brain.”
A nine-word short form has also been introduced to improve the utility of the test in assessment of patients with severe cognitive dysfunction. The CVLT-II underwent nationwide standardisation with a final normative reference sample consisting of 1087 individuals in the US. The education level was also included as a stratification variable.
