Several structural features of synapses have been found to be altered by behavioral experience. One of the most obvious features is the size of synapses. Larger synapses may release more neurotransmitter or have more receptors, such that a size change could indicate a strength change. Early findi ...

Most Hebbian learning rules or BCM rules used to describe receptive field development exhibit a spontaneous separation of synaptic weights into two groups, i.e., strong and weak synapses, so that the distribution of synaptic weights is bimodal. This implies that even rather ‘weak’, non-significant c ...
