Synaptic Plasticity During Learning
Neurons communicate at junctions called synapses, and changes (plasticity) of these synapses underlie the ability of humans to learn. Synapses are dynamic structures that can change their chemical activity within seconds. Some of these short-term changes involve the cytoskeleton (specifically actin filaments) within the dendritic spine to change only its shape. Modulation of cyclic AMP and protein kinase C pathways are also important in this process. There are also long-term changes in synapses: early and late long-term potentiation (LTP). Early LTP involves activation of calcium calmodulin ...
