engramkäsite

Engram is a term used in psychology and neuroscience to describe a unit of memory. The concept was first introduced by Richard Semon in 1896, and it has since been refined and expanded upon by various researchers. Engrams are believed to be the physical changes in the brain that occur as a result of learning or experience. These changes can be long-lasting and are thought to be responsible for the retention of information.

Engrams are typically associated with the formation of new synapses, the strengthening of existing synapses, or the modification of neural circuits. The exact mechanisms by which engrams are formed and stored are still not fully understood, but research suggests that they involve the release of neurotransmitters and the activation of specific neural pathways.

Engrams can be categorized into different types based on their duration and the type of information they store. For example, short-term engrams are associated with immediate recall of information, while long-term engrams are responsible for the retention of information over extended periods. Additionally, there are different types of engrams based on the type of information they store, such as declarative engrams (facts and events) and procedural engrams (skills and habits).

The study of engrams is important for understanding how the brain processes and stores information, as well as for developing treatments for memory-related disorders. Research in this area continues to evolve, with new findings and theories emerging as our understanding of the brain and memory deepens.
