Location of saccade-related neurons in the macaque superior colliculus

Ma, T.P., Graybiel, A.M., Wurtz, R.H.·1991·Experimental Brain Research

Abstract

The locations of saccade-related neurons were studied in the superior colliculi of two adult rhesus monkeys (Macaca mulatta) by placing marking lesions at the sites of physiologically characterized cells and comparing these histologically identified sites with the collicular laminae and acetylcholinesterase (AChE)-rich patches. Three major conclusions were drawn on the basis of 39 histologically identified sites at which saccade-related neurons were recorded. First, saccade-related neurons were distributed from the ventral half of the optic layer through the deep gray layer, and were most concentrated in the intermediate gray and white layers. Second, there was a clear relationship between the discharge characteristics of these saccade-related neurons and the depths at which they were found. Neurons having presaccadic bursts, defined as clipped and partially-clipped, tended to be encountered more dorsally, and neurons that did not have bursts (unclipped) were encountered more ventrally. Although cells having different discharge characteristics seemed to be organized along a dorsoventral axis, there was no compelling evidence that these properties were specified by their laminar locations. Third, there was no clear correlation between the locations of saccade-related neurons and the distribution of individual AChE-rich patches. Saccade-related cells were found both in the caudal superior colliculus where patches were located and in the rostral superior colliculus where patches were not found; both within and between the two tiers of AChE-rich patches in the caudal superior colliculus; and both within and between individual AChE-rich patches. However, the depth-level at which saccade-related neurons occurred generally matched the region bounded by the two tiers of AChE-rich patches in the intermediate and deep layers, and the dorsal and ventral extent of saccade-related neurons was the same as that of the AChE-rich patches.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
