The role of frontal eye-fields and superior colliculi in visual search and non-visual search in rhesus monkeys

open access: yesBehavioural Brain Research, 1982
Rhesus monkeys were tested on a visual search task in which they had to find and retrieve a peanut from a display of visually similar but inedible objects. The speed with which they did so was measured.

Neurogenetic gradients in the superior and inferior colliculi of the rhesus monkey

Journal of Comparative Neurology, 1981
AbstractThe spatiotemporal patterns of neurogenesis in the superior colliculus (SC) and inferior colliculus (IC) were analyzed by plotting the positions of heavily labeled neurons in autoradiograms from a series of rhesus monkeys that had been exposed to 3H‐thymidine at various embryonic (E) days and killed either shortly thereafter or at 2–3 months ...

Retinal ganglion cell survival and neurite regeneration requirements: the change from Müller cell dependence to superior colliculi dependence during development

open access: yesDevelopmental Brain Research, 1987
A study has been made of the effects of MÜller conditioned media or neonatal superior collicular extracts on the survival in dissociate culture of retinal ganglion cells (RGC) from differently aged rats.

Effects of ablations of the superior colliculi on spectral sensitivity in monkeys

Neuropsychologia, 1975
Abstract Spectral sensitivity of rhesus monkeys was determined before and after the total ablation of the superior colliculi. The hypothesis tested was that photopic spectral sensitivity would not be affected by the colliculectomy whereas the monkeys would loose scotopic sensitivity. This hypothesis was derived from the fact that photopic sensitivity

THE SUPERIOR COLLICULI

Archives of Surgery, 1939
The function of the collicular bodies of the quadrigeminal plate in man, and particularly that of the superior (or anterior) colliculi, remains undetermined. Not only has little experimental work been devoted to the problem, but little suitable human material has been available for study.

Auditory and visual interactions between the superior and inferior colliculi in the ferret

European Journal of Neuroscience, 2015
AbstractThe integration of visual and auditory spatial information is important for building an accurate perception of the external world, but the fundamental mechanisms governing such audiovisual interaction have only partially been resolved. The earliest interface between auditory and visual processing pathways is in the midbrain, where the superior (

Differential color responses from the superior colliculi of squirrel monkeys

Vision Research, 1966
Abstract Color sensitivity of the superior colliculi was investigated in squirrel monkeys. Evoked potentials were recorded from the colliculi in response to red and blue light stimulation. Color sensitivity of the superior colliculus was indicated by: differences in latency of potentials evoked by different color stimuli, differences in amplitude of ...

Organization and origin of the connection from the inferior to the superior colliculi in the rat

Journal of Comparative Neurology, 2006
AbstractThe inferior colliculus (IC) is the main ascending auditory relay station prior to the superior colliculus (SC). The morphology and origin of the connection from inferior to superior colliculus (I‐SC) was analyzed both by anterograde and retrograde tracing.
