Findings (IMAGE)
Caption
This graphic presents a summary of the findings. Pharmacological reversible shutdown experiments of the cerebellar cortex revealed that the memory produced by massed learning is maintained in the cerebellar cortex, whereas the memory produced by spaced learning is maintained in the cerebellar nuclei (VN), indicating "trans-synapse memory trace transfer" occurs by spaced learning. Because local applications of protein synthesis inhibitors (anisomycin or actinomycin D) blocked the spaced learning, the proteins synthesized during spaced training protocols may play a key role in trans-synapse memory trace transfer.
