A model of LGN input to layer 4C of macaque primary visual cortex
has been used to test the hypothesis that feedforward convergence of P and M
inputs on to layer 4C spiny stellate neurons is suffcient to explain the
observed gradual change in receptive field size and contrast sensitivity with
depth in the layer. Overlap of dendrites of postsynaptic neurons between M
and P input zones proved sufficient to explain change in the lower two-thirds
of layer 4C, while more rapid change in upper 4C was matched by proposing two
different M inputs with partial overlap in upper 4C alpha.
