Disruptions caused by specific drugs, antibodies and gross physical trauma can block the effects of synaptic consolidation.

Meanwhile, neuropharmacological studies of selected brain areas began to shed light on the molecules possibly responsible for fast consolidation.Molaison also showed signs of retrograde amnesia spanning a period of about 3 years prior to the surgery suggesting that recently acquired memories of as long as a couple years could remain in the MTL prior to consolidation into other brain areas.Research into other patients with resections of the MTL have shown a positive relationship between the degree of memory impairment and the extent of MTL removal which points to a temporal gradient in the consolidating nature of the MTL.Synaptic consolidation is achieved faster than systems consolidation, within only minutes to hours of learning in goldfish.LTP, one of the best understood forms of synaptic plasticity, is thought to be a possible underlying process in synaptic consolidation.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.The standard model of synaptic consolidation suggests that alterations of synaptic protein synthesis and changes in membrane potential are achieved through activating intracellular transduction cascades.These molecular cascades trigger transcription factors that lead to changes in gene expression.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 two proposed the perseveration-consolidation hypothesis after they found that new information learned could disrupt information previously learnt if not enough time had passed to allow the old information to be consolidated.

    I feared that so intimate a theory might fall short due to us being middle-class, timid royalists (after this week); that perhaps the exuberant facilities of the Forum were now the sole motivation for success at Exeter.
