Scientific activity

The research work has been performed in several research groups, with the use of electrophysiological and morphological methods or mathematical modelling.

The results of the scientific experiments carried out in the Department of Neurobiology may be grouped into six following publication cycles:

  1. Electrophysiological investigations of evoked contractions of motor units in rat and cat muscles: mechanisms of force summation and regulation in motor units and summation of motor unit forces.
  2. Electrophysiological investigations of motoneurones, spinal neuronal networks, and pathways interconnecting spinal centres to the brainstem and the cerebellum in cat and rat (microelectrode intracellular recording and stimulation techniques).
  3. Morphological studies on single neurones and their projections in the brainstem,cerebellum and spinal cord in the rabbit and rat (intracellular labelling with retrograde transport of horseradish peroxidase and fluorescent tracers).
  4. Studies on muscle innervation and structure of muscle fibers using glicogen depletion technique and PAS reaction.
  5. Studies on plasticity of the neuromuscular system (motor unit force and electrical properties) under physiological and pathological conditions: interspecies differences and sexual dimorphism, effects of aging and neurodegenerative disorders, effects of spinal cord lesions, effects of exercise training.
  6. Mathematical modelling of motor unit contractions and their summation, and modelling of spinal cord neuronal networks.
  7. Studies on mechanomyographic signals evoked during motor unit activity.

The results of the research work performed at the Department were published in over 150 articles and books, and were presented on scientific congresses.
