This synapse is formed between the axon terminal
(presynaptic neuron) sending information and the neuron dendrite (postsynaptic neuron) receiving information.
Individual axons were followed up to their entry into the grey matter, and individual terminal branches arborizing into target cortical areas were finally selected for computer-assisted 3D reconstruction on the basis of the following criteria: absence of branching points previous to entry in the target cortex (with the exception of the cut end of the thicker parental branch) and the entire arbor of the axon terminal
should appear to be contained within a single thick section.
Eleven of the 16 peripheral processes having club-like endings did not branch between the cell body and the axon terminal
When an action potential travels along a nerve and arrives at the axon terminal
, it triggers the secretion of a neurotransmitter that allows the passage of a signal from one neuron to its neighbour via the synaptic cleft.
It provides the genetic programming for the development of a protein called "dopamine." This protein is a neuro-transmitter that is released from a pre-synaptic axon terminal
of a nerve cell.
Synaptic bouton: A button-like swelling on an axon where it has a synapse with another neuron; also known as axon terminal
, presynaptic terminal, or synaptic knob.
Regional specificity of chandelier neuron axon terminal
alterations in schizophrenia.
When one neuron connects with another, an axon terminal
from the first cell reaches out and almost touches a dendrite of the other, leaving a gap of about a millionth of an inch.
These potential donors allowed vast options of anastomotic reconstruction, with many axon terminal
buds crossing the reconstruction area toward the injured nerve.
A specialized structure at the tip of the axon of the presynaptic neuron, termed the axon terminal
, contains small packets known as vesicles, which are filled with neurotransmitter molecules.
The cell numbers remained elevated at 30 days PD suggesting that CNTF may play a role in the sprouting process within the axon terminal
In contrast, inputs in vertebrate neurons generally are exclusively received over the soma and its dendritic tree, quite separate from the output region at the axon terminal
