3 Storing and Consolidating Memories Free Online FlashCards

What is working memory?

Working memory temporarily maintains and uses information relevant to a current task.

What is synaptic plasticity in memory?

Synaptic plasticity is activity-related change in how effectively neurons communicate, helping establish or modify memory representations.

What is memory consolidation?

Memory consolidation comprises processes that make newly formed, fragile memories more stable.

Besides holding information, what can working memory do?

It lets you manipulate information, such as mentally adding numbers or comparing ideas.

How do brain networks support working memory?

It relies on coordinated brain-network activity and control processes that direct attention and protect relevant information from distraction.

How can rehearsal help working memory?

Working memory is limited; silently rehearsing information can help keep it available briefly.

What do semantic and episodic memory represent?

Semantic memory concerns facts; episodic memory concerns personally experienced events. Both are forms of declarative memory.

How are long-term memories represented in the brain?

Long-term memories are represented across networks, not stored as complete records in one brain location.

What role does the hippocampus play in new memories?

The hippocampus and related medial temporal lobe structures are especially important for forming many new memories and linking parts of an experience.

What characterizes synaptic consolidation?

Synaptic consolidation occurs over minutes to hours after learning, as cellular and molecular changes help stabilize altered connections.

What characterizes systems consolidation?

Systems consolidation unfolds over a longer period as interactions between the hippocampus and neocortex help reorganize memory-supporting networks.

Does systems consolidation simply transfer a finished memory to the cortex?

No. Information is represented in cortical networks from learning onward; consolidation is not simply moving a finished memory from the hippocampus to the cortex.
