Tectotectal interactions through the commissure of the superior colliculi: An electrophysiological study

Experimental Neurology, 1981
Abstract The interaction between both superior colliculi through the collicular commissure was studied in cats. Stimulation of the optic tract and superior colliculus elicited a positive potential on the contralateral superior colliculus, recorded between 1.5- and 4.5- or 5.0-mm depth.

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 ...

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

Some Observations on the Superior Colliculi of the Cat by J. Altman

open access: closed, 1961
The observations I should like to communicate to you in this discussion on the optic tectum were made by Dr. Joseph Altman in the course of his work for a doctoral dissertation2. Dr. Joseph Altman undertook these studies for three reasons: 1. Just as Professor Doty, he believes that the optic tectum may play a greater role in the visually-guided

Evidence that superior colliculi are involved in the control of amygdala-kindled seizures

Neuroscience Letters, 1990
The effects of bilateral high radiofrequency lesions of superior colliculus (SC) were studied on amygdala kindling. The results demonstrate that a selective destruction of the SC only slightly facilitated the development of kindling. However, the most remarkable effect was the increase of afterdischarge and motor seizure duration observed when SC ...
