ABSTRACT Almost all theoretical and experimental
studies of the mechanisms underlying learning and memory
focus on synaptic efficacy and make the implicit assumption
that changes in synaptic efficacy are both necessary and
sufficient to account for learning and memory. However,
network dynamics depends on the complex interaction be-
tween intrinsic membrane properties and synaptic strengths
and time courses. Furthermore, neuronal activity itself mod-
ifies not only synaptic efficacy but also the intrinsic membrane
properties of neurons. This paper presents examples demon-
strating that neurons with complex temporal dynamics can
