Central Auditory Pathways in the Brain Stem and Inferior Colliculi
Acta Oto-Laryngologica, 1958The ramifications and connections of the ascending auditory pathway within the brain stem from the entrance of the auditory nerve up to the inferior colliculi has been studied in decerebrated cats using electrophysiologic methods. Suitable acoustic stimuli were achieved with “click impulses”.

Organization and origin of the connection from the inferior to the superior colliculi in the rat
Journal of Comparative Neurology, 2006AbstractThe 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.

We report a clinical case of a 19-year-old male patient who developed pure word deafness due to the local compressive effect of a pineal germinoma on the inferior colliculi of the quadrigeminal plate. After percutaneous radiation therapy the size of the tumor decreased significantly, while audiometry demonstrated a complete regression of the auditory ...

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 ...

Abstract Mice not normally susceptible to audiogenic seizures can be rendered so by exposing them to a brief intense sound during a certain developmental period (acoustic priming). To determine the effects of priming on central auditory activity, single-unit extracellular recordings were obtained from the inferior colliculi of primed C57BL/6J mice ...

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, 2008Neurophysiological 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

Abstract In C57BL 6J mice, which are not normally susceptible to audiogenic seizures, a single exposure to an intense acoustic stimulus between the ages of 12 and 26 days renders the animals susceptible thereafter to audiogenic seizures. This phenomenon is known as “acoustic priming”.

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

AbstractEpilepsy is tightly associated with dysfunction of inhibitory γ-aminobutyric acid (GABA) neurotransmission. In this study, Krushinsky-Molodkina (KM) rats genetically prone to audiogenic seizures (AGS) were used. KM rats are characterized by the development of audiogenic epilepsy during postnatal ontogenesis, with AGS onset at the age of 1.5-2 ...
