1. Muscle Physiology (structure of skeletal muscles, sliding filament theory of muscle contraction, simple muscle mechanics, force-length and force-velocity relationships)
2. Motor units and electromyography (fast and slow motor units, Henneman principle, functional roles of motor units, recording and processing of electromyographic signals)
3. Spinal control of movement (monosynaptic and polysnaptic reflexes)
4. Voluntary control of a single muscle (feedforward and feedback control, servo control, servo hypothesis, equilibrium point hypothesis)
5. Voluntary control of single joint movements (isotonic movements and isometric contractions, kinematic and EMG profiles of single joint movements, dual-strategy hypothesis)
6. Cortical and subcortical control (roles of cerebral cortex, basal ganglia and cerebellum in motor control, activity in these structures before and during movement assessed by means of single cell recordings, neuroanatomical tracing, neuroimaging methods)
7. Ascending and Descending Pathways (Dorsal column pathway, spinocervical, spintothalamic, spinocerebellar, spinoreticular, pyramidal, rubrospinal, vestibulospinal and reticulospinal tracts)
8. Control and coordination of multijoint movements (merging neurophysiology with control, force control hypothesis, generalized motor programs, internal models, equilibrium point control)
Servo hypotheses for the biological control of movement.
