A postdoc position is available from January 15, 1998, for studies of
sensorimotor mechanisms involved in control of the human hand in
manipulative tasks. In the laboratory we apply analyses ranging from the
study of peripheral sensor and effector properties, to analyses of
sensorimotor control strategies and related cognitive functions. We
characterize manipulative actions with multidimensional recording of
fingertip forces, torques and movements, and we analyze muscular activation
and efferent motoneuron signals with multichannel EMG-techniques. We use
microneurographic techniques to learn how individual sensors in the hand
and arm system encode various biomechanical events in the digit-object
interfaces. To critically assess how these afferent signals are used in
control terms we also study impairments after selective nerve conduction
blocks. The use of visual cues and memory mechanisms in forward control of
fingertip forces and torques are related areas of experimentation. Finally,
to analyze CNS processes that supports manipulative actions we use EEG and
transcranial magnetic brain stimulation, and in recently initiated
collaborative projects we use PET and MEG techniques to analyze activity in
distributed human neural networks. Prospective applicants may visit the ISI
database to see what we have been doing.
The candidate is expected to work independently on a focused research
project of her/his choice for a one year (minimum) term. Apart from an
appropriate understanding of biomechanics, applicants should have a
background in neurophysiology and experience of experimental work with
human subjects. It is an advantage to have a medical degree. Experience
from modeling of either neural strategies used for learning and controlling
movements or from soft tissue mechanics is likewise of advantage.
Candidates should send a letter with her/his CV and names of two
references. Queries should be sent to Roland.S.Johansson@physiol.umu.se.
Material by regular mail to prof. Roland S Johansson, Department of
Physiology, Umea University, S-90187 Umea, Sweden. (Telefax: +46-90-786 6683).
