Jan 17, 2007. The neural mechanisms for the formation of declarative memory (memory for facts and events) are believed to be integrated from processes mediated by hippocampal long-term potentiation (LTP) and long-term depression. (LTD). Traditionally, LTP has been designated as the main mediator of spatial.
Clearly some mechanism which helps create memories was damaged. In later years, researchers discovered that the hippocampus, which had been removed in HM's surgery, is primarily responsible for the consolidation of short-term into long-term memories. This process can take up to three years, hence HM's retrograde.

Traditionally, LTP has been designated as the main mediator of spatial memory storage in the.
Key words: long-term potentiation, hippocampus, declarative memory, aversive memory. The opposite process, long-term depression (LTD) has also been recognized and proposed to play a role in learning (see Bliss and Collingridge 1993, Ito 2005, Mechanisms of emotional arousal and lasting declarative memory.

May 25, 2004. The mechanism for encoding this type of information is as yet unidentified. Memory is achieved by experience-dependent changes in synaptic strength. These changes can take the form of persistent enhancements (long-term potentiation, or LTP), or long-term depressions (LTD), of synaptic transmission.
Hippocampal long-term depression is facilitated by the acquisition and updating of memory of spatial auditory content and requires mGlu5 activation.

Scientists further categorize long-term memory as either declarative or nondeclarative (Squire, 2004). Declarative memory refers to memories that can be consciously recalled such as facts and events. Declarative memory involves one memory system in the brain (and the brain has several). An example of declarative.
