Examples
A typical synapse, then, is a contact between the axon of one neuron and a dendrite or soma of another.
During development dendrite morphology is shaped by intrinsic programs within the cell's genome and extrinsic factors such as signals from other cells.
The dentate granule cell axons (called mossy fibers) pass on the information from the EC on thorny spines that exit from the proximal apical dendrite of CA3 pyramidal cells.
Passive cable theory describes how voltage changes at a particular location on a dendrite transmit this electrical signal through a system of converging dendrite segments of different diameters, lengths, and electrical properties.
The action potential propagates the electrical activity along the membrane of the dendrite to the cell body and then afferently down the axon to the terminal buttons where it crosses the synapse.
Therefore, plasticity that leads to changes in the dendrite structure will affect communication and processing in the cell.
