Cortical plasticity: It's all the range!
When rats learn a motor skill, synaptic potentials in the motor cortex are enhanced. A new study has revealed that this learning-induced enhancement limits further synaptic potentiation, but not synaptic depression. These findings support the view that activity-dependent synaptic plasticity is the brain's memory mechanism.
