Interhemispheric engram transfer in chick.

    Summary
    This summary is machine-generated.

    Interhemispheric memory transfer in chicks depends on how recently the memory trace (engram) was formed. Early access facilitates transfer, while later access requires more attempts for successful memory transfer.

    Area of Science:

    • Neuroscience
    • Memory Consolidation
    • Learning

    Background:

    • Monocular training establishes memory engrams in the chick forebrain hemisphere contralateral to the trained eye.
    • Interocular transfer of learned information necessitates the naive hemisphere accessing the engram in the opposite hemisphere.

    Purpose of the Study:

    • To investigate the impact of accessing a unilateral engram on the untrained hemisphere during early consolidation stages.
    • To determine how the recency of engram formation influences interhemispheric memory transfer.

    Main Methods:

    • Chicks underwent monocular training on a passive avoidance task.
    • Interocular transfer tests were conducted at 7.5 minutes and 30 minutes post-learning.
    • Amnesia was induced using ouabain or cycloheximide to assess memory retention.

    Main Results:

    • A single access trial at 7.5 minutes post-learning facilitated engram transfer to the naive hemisphere.
    • Five access trials were required at 30 minutes post-learning to achieve engram transfer.
    • These findings confirm that accessing a unilateral engram can lead to interhemispheric memory transfer.

    Conclusions:

    • Interhemispheric memory transfer is dependent on the recency of the unilateral engram's formation.
    • The number of access trials needed for transfer varies with the consolidation stage of the memory engram.
