Proposed mechanisms of memory ALL involve changes at synapses
Learning promotes facilitation of synaptic transmission
This illustration shows several chemical synapses in the nervous system.
Notice that a synaptic terminal may have a synapse that influences its output of neurotransmitter. With this arrangement, a neural network can operate a "gateway" in which information can be "cut off" or "enhanced" before moving further along.
