Neuroscientist have discovered a mechanism that contributes to the strengthening of associations, also called synapses.
<h3>What are synapses?</h3>
A synapse is a physical component of the nervous system that enables a neuron (or nerve cell) to transmit an electrical or chemical signal to an additional neuron or to the intended effector cell.
The transfer of nerve impulses from one neuron to another requires synapses. Synapses are the way by which neurons, which are specialized to convey messages to specific target cells, accomplish this. The plasma membrane of the target (postsynaptic) cell and the plasma membrane of the signal-passing neuron are in close proximity at a synapse. The large arrays of molecular machinery that link the two membranes and carry out the signaling process are present at both the presynaptic and postsynaptic locations. Many synapses have an axon for the presynaptic component and a dendrite or soma for the postsynaptic component. Additionally, astrocytes communicate with synaptic neurons, responding to synaptic activity to control neurotransmission.
