Figure 5.10 Massone and Bizzi’s (1989) computational model used
to compute hand trajectory and muscle activation over time. The
network is the Jordan Sequential Network. Here, the input is
represented by a highlighted location in a 15 x 15 grid. Input
units, or plan units, coarsely code the sensory world, sampling a 3
x 3 space, and computing an average over that space. Output units
to the muscles encode a sequence of a set of muscle activations.
