The Neural Mechanisms of Learning
... When a neurotransmitter is repeatedly sent across the synapse, the presynaptic neuron and postsynaptic neuron are repeatedly activated at the same time. This has the effect of actually changing the chemistry of the synapse, leading to a strengthening of the connections between the neurons at the syn ...

Protocadherin mediates collective axon extension of neurons
... Protocadherins are broadly classified as being either clustered or non-clustered. Past studies suggest that clustered protocadherins have some function in the self-repelling mechanism of dendrites to prevent binding between dendrites from the same neuron, while non-clustered protocadherins have been ...
