TI  - A four group classification of the rat superior collicular cells responding to 
      optic nerve stimulation.
PG  - 367-84
AB  - With lightly anesthetized rats, activities of single cells responding to single 
      optic nerve (ON) shocks were recorded from the superficial layers of the superior 
      colliculus, i.e., St. zonale(SZ), St. griseum superficiale (SGS) and St. opticum 
      (SO). According to response latencies and recording depths, four classes of cells 
      were identified: I-, II-, III-, and IV-cells. Class I cells, recorded in the SZ 
      or the upper half of SGS, were innervated by slowly conducting ON fibers of 
      velocities slower than 4 m/sec. Class II cells, recorded from the middle part of 
      the SGS, were innervated by ON fibers of intermediate velocity (4--8 m/sec). 
      Class III cells, recorded from the lower half of SGS or the upper part of SO, 
      were innervated by fast conducting ON fibers (faster than 8 m/sec). Class IV 
      cells were recorded from the depth similar to the class III but they were 
      innervated by slowly conducting fibers (4-1.7 m/sec). Class I cells revealed a 
      long-lasting inhibition after initial excitation, being a sharp contrast with 
      cells of classes II and III which were almost free from inhibition. Inhibition 
      exerted upon class IV cells were of intermediate strength. Possible anatomical 
      correlates of the four classes of cells and hypothetical modes of their ON 
      innervation were discussed.
