Eyecup withdrawal in the crab, Carcinus, and its interaction with the optokinetic response
Summary 1. Protective withdrawal of the eyecup is caused by a burst of impulses in two axons of the optic tract, one to muscles 19a, 19b and 20a, the other to muscles 18, 20b, 21 and 22. 2. At a reflex eyecup withdrawal other concurrent activity is mechanically overridden ; the tonic activity in only one muscle is inhibited centrally. At a ‘spontaneous’ withdrawal, however, all motor activity to that eyecup is inhibited. 3. The largest muscle, 19a, inactive in other eyecup movements, is...[Show more]
