engramkäsitettä

The term engramkäsitettä, originating from German, translates to "engram concept." An engram, in the context of memory, refers to the hypothetical physical or biochemical trace of a memory in the brain. The concept suggests that a specific memory is stored by a unique pattern of neural connections or changes within neurons. The idea of the engram was first proposed by Richard Semon in 1904 as a way to explain how experiences leave lasting impressions on the nervous system.

While the exact nature and location of engrams remain a subject of ongoing research and debate within neuroscience, the underlying principle is fundamental to understanding memory formation and storage. Scientists explore various mechanisms that could contribute to engram formation, including synaptic plasticity, alterations in gene expression, and the recruitment of specific neuronal ensembles. The engram concept provides a theoretical framework for investigating how learning and experience modify the brain and lead to the retention of information over time.
