Memory consolidation or updating consolidation dating sites with hook ups
An efficient way to form a new declarative memory is to repeat a short-term training many times with a rest between the training sessions, because the learned memory is consolidated after training.This suggests that the brain still keeps actively working even after training, but the synaptic dynamics during posttraining periods has been studied rarely.and occurs within the first few hours after learning, and systems consolidation, where hippocampus-dependent memories become independent of the hippocampus over a period of weeks to years.Recently, a third process has become the focus of research, reconsolidation, in which previously-consolidated memories can be made labile again through reactivation of the memory trace.After Molaison underwent a bilateral medial temporal lobe resection to alleviate epileptic symptoms the patient began to suffer from memory impairments.Molaison lost the ability to encode and consolidate newly learned information leading researchers to conclude the medial temporal lobe (MTL) was an important structure involved in this process.
In the study, 115 participants watched a series of six film clips containing real-life footage of humans and animals in distress, a procedure regularly used to investigate causal factors in the development of PTSD.
The case of Henry Molaison, formerly known as patient H.
M., became a landmark in studies of memory as it relates to amnesia and the removal of the hippocampal zone and sparked massive interest in the study of brain lesions and their effect on memory.
The posttraining memory consolidation is also observed in cerebellar motor learning.
To investigate the mechanism, we formulated a simple theoretical model of the cerebellum with a minimal number of elements and learning-related changes in synaptic efficacy at multiple locations.
Updating also led to the greatest decrease in distress and the greatest changes in physical arousal (as measured by skin conductance) when participants were faced with reminders of the trauma.
