Abstract. Convergence between cells which differ in
both spatial and temporal properties create higher or-
der neurons with responseproperties that are distinctly
different from those of the input neurons. The spatial
properties of target neurons are not necessarily"cosine-
tuned". In addition, unlike the independence between
spatial and temporal properties in cosine-tuned afferent
neurons, higher-order target cells generally exhibit a
dependenceof temporal dynamics on spatial properties.
The response properties of target neurons receiving
spatio-temporal convergence (STC) from tonic and
phasic-tonic or phasic afferents is investigated here by
considering a general case where the dynamic input is
represented by a fractional, leaky, derivative transfer
function. It is shown that, at frequencies below the
