| Research Abstract |
Memory formation at synapse is a kind of transformation from electrical activity to morphological and composing protein changes Although synaptic molecules are localized at synapse by passive and positive transportation and assembled by themselves autonomically, it is unclear whether the behavior of synaptic molecules are changed by synaptic activation. We examined paGFP-tagged CaMKII behavior at synapse by 2p-photoconversion. The motility of CaMKII were slower than that of GluR1 receptors. This indicates that CaMKII which has been activated once can activate AMPA receptors coming into the synapse.
