Long-term changes in experience cause neurons to sprout new long-lasting connections
...s team was looking to see if persistent changes in connectivity occurred after a long-term change in experience. They focused on the formation of new long-lasting spines that indicate robust connections between a neuron's highly branched dendrites and nearby axons. Dendrites are the input side of neurons and axon...New roles for growth factors: Enticing nerve cells to muscles
