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 ...

Abstract Epilepsy 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.

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

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 ...

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”.

[Behavior of cats after unilateral section of the brachii of the inferior colliculi].
Zhurnal vysshei nervnoi deiatelnosti imeni I P Pavlova, 1978In experiments on 13 cats a unilateral section of the brachii of inferior colliculi produced a stable interhemispheric asymmetry not only in the auditory system, but in other (vestibular, visual, somatic, olfactory) analysers as well, which led to a disturbance of adequate space perception.

AbstractThe trigemino‐tectal projections were investigated with anterograde and retrograde tracing techniques in the Madagascan lesser hedgehog tenrec, Echinops telfairi. There were prominent contralateral projections to the inferior colliculus (CoI) and the superior colliculus (CoS), each showing its own characteristic pattern of terminations.

Evoked potentials to acoustic stimuli were recorded in the temporal cortical area, the medial geniculate body and the posterior lateral thalamic nucleus in acute experiments on anaesthetized cats. Section of the brachia of the inferior colliculi in an acute experiment resulted in the disappearance of potentials in the examined structures.

The EP-series response of the inferior colliculus to clicks simulating sound source motion, reflects characteristics of this "motion" ("the motion effect", ME). ME distribution over the inferior colliculus practically coincided with the spatial distribution in cases when contralateral stimulation was more effective than the ipsilateral one. The spatial

After a bilateral ablation of the rat auditory cortex, differentiation of a tonal signal from an amplitude-modulated stimulus with 50 c/s modulation frequency is preserved, while ablation of the posterior colliculi completely abolishes differentiation of these signals, without subsequent restoration in six months after the operation.
