in a little Google neurology review found a really marvelous resource:
http://sky.bsd.uchicago.edu/lcy_ref/synap/synapse.html by Dave Atkins at
George Wash U. in DC
...that beautifully describes the difference between bi-directional
electrical synapses and the various types of one directional chemical
synapses, and lots more. Two of various new puzzles I came across are
that some purely 'structural' brain cells (astrocytes) apparently have
large mediating influences, and that the synaptic gaps (clefts)
separating the two sides is a closed space "blanketed by neural
connective tissue cells (glia)". In an earlier post I compared the
openness of the cleft to freely circulating neural fluid (which is
apparently not free flowing at all) as a structure allowing cross
fertilization of the neuron-to-neuron signals as between pistol and
stamen in flowers. Oh well, that's what a drawing board is for,
supplying the waste basket!
