Memories become more permanent over time and can be influenced by sleep because of what process?

Question

BlackTom AI · Accepted Answer

The question asks about a process by which memories become more permanent over time and can be influenced by sleep.
Option 1: consolidation. This option names the standard memory process where transient labile memories are stabilized into more durable long-term traces, and sleep is known to facilitate this stabilization.
Option 2: reconsolidation. While reconsolidation occurs when a stored memory is reactivated and then stored again, it is not typically described as the phase by which memories become permanently established over time; it refers to updating or modifying existing memories after retrieval.
Option 3: short-term potentiation. Short-term potentiation describes a temporary increase in synaptic strength that lasts minutes to hours and often contributes to short-term enhancements, not the long-term stabilization of memories; it does not by itself explain sleep-related lasting changes.
Option 4: long-term potentiation. LTP is a long-lasting enhancement of synaptic efficacy and is a neural mechanism related to learning and memory, but the question emphasizes the process by which memories become more permanent over time and sleep’s influence, which is better captured by consolidation as the overarching process that stabilizes memories after encoding and during sleep-related processing.
In summary, consolidation is the umbrella term that explains both the gradual stabilization of memories into permanent traces and the role sleep plays in strengthening and preserving them, whereas the other options refer to related phenomena or mechanisms that do not fully address the described process.
