Synapses are formed between neurons and also with targets that are not part of the nervous system, e. Axon terminals, under the direction of a variety of extracellular cues, grow towards particular targets.
Once they arrive at the target, they stop growing and the growth cone changes to form a synapse. As with axon growth, the formation of the synapse is dependent on an interaction between the target and the growth cone.
But unlike axon growth, the exchange of chemical signals also operates from neuron to target; the presynaptic terminal releases neurotransmitter and other signals which influence the target. Once formed, the synapse continues in a state of continual change, able to alter its size, its precise location on the target and the extent to which it communicates with the target.
These processes of change are essential to allow for adjustment as the animal grows and to allow the accretion of experience, usually known as learning.In a rodent study, it was found that adult rats that had been given difficult acrobatic training experienced synaptogenesis, whereas rats assigned to a physical exercise task or inactivity failed to .
Psychology Definition of SYNAPTOGENESIS: The formation of synapses between neurons as the axons and dendrites grow.

According to autoradiographic determinations of granule cell birth datesZ,3, there exist dorsal-ventral and possibly temporo-septal gradients in cell age.
Jun 18, · Therefore, the present study examined two developmental markers in chimpanzees, synaptogenesis and dendritic growth of pyramidal neurons, in four regions, including prestriate visual (area 18), primary motor (area 4), primary somatosensory (area 3b), and prefrontal (area 10) cortices.

Synaptogenesis is a fancy scientific term that just means nerve cells are making new connections. It occurs throughout life, but there are at least two periods during which it happens at a much.
