If you can explain "thought" by the firing of neurons, then please
keep December 10 open for a trip to Sweden because the Nobel
Foundation is sure to come calling.
More seriously, the working out of brain function involves far more
than neurons 'firing' action potentials. There is an enormous amount
of analog (continuously variable) signal processing going on in the
microcircuitry of the dendrites and anaxonal or short axonal neurons,
not to mention all the biochemical and molecular biological of the
second messenger metabotropic synapses to account for. All these
factors probably play a larger role in establishing the phenomenon we
call 'thought' than simple action potentials.
Short term memory has many guises and is important for all aspects of
neural function including sensory and motor processing. There is no
one single short-term memory store.
