Abstract
We use spontaneous motor pattern deletions in spinal frogs to test a computational theory of movement construction. We hypothesize that at the spinal level, operating in isolation from the brain, the forces driving movements are constructed from summation of force-field primitives of fixed temporal dynamics, which can be expressed in the form
F(r,
r
̇
,t)=
∑
i
A
ia(t+τ
i)φ
i(r,
r
̇
)
where
A
i
is a scaling parameter,
a(
t) is a common timing dynamics for each primitive, time shifted for each by
t
i
and
φ(r,
r
̇
)
are functions of limb state. In deletions, the force amplitudes, force directions and patterns behave as predicted by this model of movement construction based on summation of force-field primitives.
