Hypothetical neuronal architecture supporting MSTd neuronal path selectivity with reference to an analogous mechanism of elementary motion direction selectivity. A: in frog retinal ganglion cells, as in other systems, moving objects evoke direction selective responses based on the successive activation of intermediate elements that interact through time-dependent excitatory and inhibitory effects. B: moving headings may evoke path selective responses in MSTd neurons based on the successive activation of receptive field subfields that interact through time-dependent excitatory and inhibitory connections.
