PSY270H5 Chapter Notes -Synapse, Memory Consolidation, Temporal Lobe
Document Summary
Time ! causing structural changes ! cortical connections are strengthened ! episodic memories ! Synaptic consolidation: interested in whats happening at the neuronal level and it is fast acting! Systems consolidation: involves multiple brain structures and can take decades ! Reconsolidating occurs when a memory is reactivated but over a much shorter time course (each time the memory is accessed it needs to be consolidated again) ! Hebb"s postulate: cells that re together, wire together (if one of them res all of them res) ! According to hebb, memories are stored in groups of cells that tend to be active at the same. We now know that long-term potentiation increases the sensitivity of post-synaptic neurons by. This is the type of memory that we need for memory ! Standard model: medial temporal lobe is particularly important for systems consolidation ! Hippocampus also plays a huge role in systems consolidation !
