The process of synaptogenesis
WebbAs soon as an axon has reached the genetically predetermined target area, synapses are formed to neighboring nerve cells in the target region. This process of synaptogenesis (formation of new synapses) is caused by the. upstream nerve cells, but also essentially modulated by glial cells, in particular by astrocytes.

The process of synaptic pruning known as synapse elimination is a presumably activity-dependent process that involves competition between axons. Hypothetically, a synapse strong enough to produce an action potential will trigger the myonuclei directly across from the axon to release synaptotrophins that will … Visa mer Synaptogenesis is the formation of synapses between neurons in the nervous system.

WebbThe process of synapse rearrangement, also referred to as synapse remodeling, is named such because some synapses are lost and new ones are also formed. This process usually takes place after cell death. Both elimination and retraction are both part of synapse rearrangement. There are several factors that play in the process of elimination.
