[Avery Andrews 930111.1200]
Has anyone tried to publish a refutation of the major conclusion of
Bizzi et al. 1976, `mechanisms underlying acheivement of final head
position', J. Neurophysiol 39:435-444?
They claim, if I read them aright, to have shown that kinesthetic
feedback is not involved in attaining the final head position when
monkeys move their heads to orient towards flashing lights, but the
behavior they report looks perfectly consistent with what you would
get with a fairly low gain kinesthetic control system, & straight
kinesthetic control would presumably be a lot simpler than what they
suggest, which is that kinesthesis is invoved in constraining that
path, but not its endpoint.
It also looks like a good subject for a modelling exercise, presumably
simple if you consider just rotation around the neck, or elevation
at the neck.
