P2: Neocortex and Memory
Authors
Abstract:
The human prefrontal cortex differs from all other mammals: the seat of complex cognition, abstract thinking, planning and future forecasting, and behavioral inhibition. Using our prefrontal cortex is a significant energy drain on the body, so despite its impressive capabilities, it’s daily capacity is limited. Some researchers estimate a mere 2-3 hours per day of activity depletes the prefrontal cortex. The prefrontal cortex modulates our limbic instincts and lets us to respond mindfully to emotionally charged situations – to a degree. An extensive body of research has shown that disruption of the hippocampus primarily affects recently formed memories, but does not impair recollection of remote memories, believed to be stored in the neocortex. In the 70’s, it has been proposed that the hippocampus serves as a simple moment-by-moment capturing system, while the neocortex stores information in a structured way. The neocortical representational areas are reciprocally connected to the hippocampus enabling linking of the neocortical representational areas by the hippocampus. The hippocampus is needed for rapid initial storage, while memories are slowly incorporated into the neocortex for stable long term storage. The slow restoration of memories in the neocortex is suggested to take place by repeated replay of the new information by the hippocampus.

The last decade has seen dramatic technological and conceptual changes in research on episodic memory and the brain. New technologies, and increased use of more naturalistic observations, have enabled investigators to delve deeply into the structures that mediate episodic memory, particularly the hippocampus, and to track functional and structural interactions among brain regions that support i...

When new learning occurs against the background of established prior knowledge, relevant new information can be assimilated into a schema and thereby expand the knowledge base. An animal model of this important component of memory consolidation reveals that systems memory consolidation can be very fast. In experiments with rats, we found that the hippocampal-dependent learning of new paired ass...

working memory impairment is one of the most important cognitive deficits in patients with mild traumatic brain injury that affect mental health status even in the early stages of the disease. the purpose of this study was to evaluate the correlation between the working memory and mental health status in traumatic brain injury (tbi) patients. this cohort study was performed on 50 tbi patients a...
