RESUMO

1. Inhibitory post-synaptic potentials (i.p.s.p.s) evoked by adequate stimulation of group Ia muscle spindle afferents of triceps surae and plantaris and by near-threshold electrical stimulation of quadriceps and hamstring nerves were recorded in a number of motoneurone species. The aim of the study was to compare the pattern of non-reciprocal Ia inhibitory actions on hind-limb motoneurones with the pattern of inhibition evoked from group Ib tendon organ afferents.
