Abstract(in English) | Models of local feedback system are well-known with the brainstem saccade generator, but they have at least two difficulties. In the present model, the activity of the superior collliculus (SC) during a saccade, when summed up temporally and spatially, holds a constant value, thus producing a correct size of the amplitude. The direction of a saccade could be encoded by the synaptic efficacy of axon terminals from the SC as in other models, but here we present a new hypothesis of population coding in the burst neuron (BN) pools. Without local feedback, the output saturation of the BNs which explains the main sequence of the saccade, does not contradict the stretch phenomena owing to the population coding of the BNs. |
