Responses of mesothoracic motor neurons to giant interneuron stimulation in the cockroach

During wind-evoked turning in the cockroach the mesothoracic (T2) legs tend to move in antiphase with the ipsilateral metathoracic (T3) legs, although this relationship is not absolute. Intracellular stimulation of giant interneurous coupled with extracellular records from leg nerves 6Br4 and 5r1 in...

Zusammenfassung:During wind-evoked turning in the cockroach the mesothoracic (T2) legs tend to move in antiphase with the ipsilateral metathoracic (T3) legs, although this relationship is not absolute. Intracellular stimulation of giant interneurous coupled with extracellular records from leg nerves 6Br4 and 5r1 indicate some substantial differences between the responses in T2 and those in T3. The data suggest that, in response to giant interneurons activity, more factors may be involved in determining the direction of leg movement in T2 than in T3.
