Central Programming and Reflex Control of Walking in the Cockroach

摘要: 1. The activity in identified motor units supplying the coxal levator and depressor muscles of cockroach have been recorded intact freely walking animals preparations after removal all sensory input from leg receptors. 2. Reciprocal motoneurones can be evoked, or occurs spontaneously, partially de-afferented preparations, thus indicating existence a central locomotory rhythm generator. 3. reciprocal patterns same moving are not identical to those preparations. Thus, production normal rhythmic movements depends some extent on receptors, this probably exerting tonic phasic effects 4. An increase resistance retraction during results an discharge rate motoneurones. This observation further demonstrates that exclusively centrally controlled. receptors responsible for reflex effect trochanteral campaniform sensilla.
