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 (

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 ...

Defective auditory recognition after small hemorrhage in the inferior colliculi

Journal of the Neurological Sciences, 1998
We report the case of a male patient with a traumatic small hemorrhage partially involving the bilateral inferior colliculi without evidence of a temporal lobe lesion. He was unable to comprehend spoken words although he had intact speech production, reading and writing abilities. Comprehension of environmental sounds was also affected.

Tonic organization of the inferior colliculi in the cat in conditions of simulated sound source motion.

Neuroscience and Behavioral Physiology, 2002
Simulation of the motion of a sound source using a series of clicks with variable interaural delays was used to study movement effects as changes in the amplitude of sequential focal evoked potentials (EP) in series of EP arising in response to the signal. These experiments showed that a) in 25% of cases the movement effect depended on the direction 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.

Laminar organization of frequency‐defined local axons within and between the inferior colliculi of the guinea pig

Journal of Comparative Neurology, 1995
AbstractWe present a comprehensive description of the local (intrinsic and commissural) connections in the central nucleus of the inferior colliculi (CNICs) in guinea pig. Focal injections of the anterograde tracer biocytin were made into physiologically identified loci of the CNIC and the spatial organisation of the labeled fibres was revealed with ...

Response of Neurons of The Inferior Colliculi of Cats To Changes in the Intensity of One of The Monaural Components of Binaurally Presented Stimuli

Soviet Psychology, 1967
In spite of the large quantity of psychophysiological investigations of binaural hearing, a systematic study of its concrete mechanisms has only been begun comparatively recently (cf. review [1]). In particular, changes in neuron response under conditions of lateral differentiation brought about by varying the intensity of one of the monaural ...

Unit responses of the inferior colliculi to changes in the intensity of an amplitude-modulated signal

Neurophysiology, 1974
Unit responses of the inferior colliculi of anesthetized rats to amplitude-modulated sounds during a change in the carrier intensity were investigated. The following unit response characteristics were assessed: the number of spikes in the response, the range of reproduction of the modulation frequency, the response duration, and the pattern of the ...

Peculiarities of time patterns of discharges of single auditory neurons of mouse inferior colliculi

Journal of Evolutionary Biochemistry and Physiology, 2008
Neurophysiological mapping of single neuronsof the central nucleus of the mouse inferior colliculus has revealed presence of four main groups ofneurons differing by distribution and ratio of excitatory and inhibitory inputs in frequency receptivefields [1, 2]. Among them there are “primary–like”neurons reproducing frequency tuning of the auditory nerve

Analysis of the State of Glutamate- and Gaba-Ergic Neurons in the Inferior Colliculi of Krushinsky – Molodkina Strain Rats at Early Stages of Epileptogenesis

Российский физиологический журнал им  И  М  Сеченова
Disturbances in the neurotransmitter systems during the development of temporal lobe epilepsy have been most detailed studied in forebrain structures – in the temporal cortex, amygdala, and hippocampus [1, 2].
