title: How effective is integration of information from muscle afferents in spinal pathways?
abstract: Integration of information forwarded by group I and group II muscle afferents to premotor interneurones was estimated from spatial facilitation in oligosynaptic (most likely disynaptic) reflex pathways from these afferents. Indications for mutual facilitation of synaptic actions of group I and group II afferents have been found on both inhibitory and excitatory premotor interneurones but were easier to demonstrate in the inhibitory pathways. However, the facilitation appeared weak under our experimental conditions and depended critically upon the intensity and timing of the stimuli used to activate muscle afferents.
