A Physiological Neural Controller of a Muscle Fiber Oculomotor Plant in Horizontal Monkey Saccades

Table 1

Firing activity of neural sites during an ipsilateral saccade [3].

Neural site	Burst onset before saccade (ms)	Peak firing rate (Hz)	Burst end with respect to saccade end
Contralateral SC	20–25	800–1000	Almost the same
Ipsilateral LLBN	20	800–1000	Almost the same
OPN	6–10	150–200 (before and after)	Almost the same
Ipsilateral EBN	6–8	600–1000	~10 ms before
Ipsilateral IBN	6–8	600–800	~10 ms before
Ipsilateral TN/IN	5	Tonic firing (before and after)	It resumes tonic firing when saccade ends
Ipsilateral AN	5	400–800	~5 ms before
Ipsilateral FN	20	Pause during saccade and a burst of 200 Hz near the end of the saccade	Pause ends with burst ~10 ms before saccade ends; it resumes tonic firing ~10 ms after saccade ends
Contralateral FN	20	200	Pulse ends with pause ~10 ms before saccade ends; it resumes tonic firing ~10 ms after saccade ends
Ipsilateral cerebellar vermis	20–25	600–800	~25 ms before
Ipsilateral nucleus reticularis tegmenti pontis	20–25	800–1000	Almost the same
Ipsilateral substantia nigra	40	40–100	It resumes firing ~40–150 ms after saccade ends
