Between-systems memory interference model

Between-systems Memory Interference Model is a theoretical framework in cognitive psychology and neuroscience that explains how different memory systems in the brain can interfere with each other. This model is based on the premise that the brain's various memory systems are not entirely independent and can influence each other's functioning.

Overview

The Between-systems Memory Interference Model posits that the hippocampus and the striatum, two key brain regions involved in memory, can interfere with each other's functioning. This interference can occur when both systems are activated simultaneously, leading to competition for neural resources.

The hippocampus (green) and the striatum (blue) are two key brain regions involved in memory.

Hippocampus and Striatum

The hippocampus is primarily involved in the formation of new long-term memories, particularly those related to events and facts (declarative memory). The striatum, on the other hand, is involved in the formation of habits and procedural memories.

Interference

Interference can occur in two ways: proactive and retroactive. Proactive interference occurs when old memories interfere with the formation of new ones. In contrast, retroactive interference occurs when new memories interfere with the retrieval of old ones.

Implications

The Between-systems Memory Interference Model has significant implications for understanding various cognitive disorders, such as Alzheimer's, where memory interference can exacerbate cognitive decline.
