Using
a
combination
if single unit recording, microstimulation, and injection of muscimol,
we
have shown that the Intersitial Nucleus of Cajal (INC) contains 'neural
integrators'
that control the three-dimensional orientation of both the eye and the
head.
We have also shown that the INC and adjacent riMLF burst neurons
utilize
a coordinate
system
similar to the semicircular canals, but aligned with the behavioral
constraints
(Listing's law, Fick strategy) observed in eye and head movements. Now
we
are looking at how these areas separately control the eye and head, and
how
they control neck muscles.
